项目启动顺序

请确保启动顺序(要先启动认证中心,再启动网关

  1. eureka
  2. config
  3. auth
  4. gateway
  5. upms

认证中心

老规矩,自上到下看代码,先从接口层看起

请求rest接口

@RestController
@RequestMapping("/authentication")
public class AuthenticationController {
    @Autowired
    @Qualifier("consumerTokenServices")
    private ConsumerTokenServices consumerTokenServices;

    /**
     * 认证页面
     * @return ModelAndView
     */
    @GetMapping("/require")
    public ModelAndView require() {
        return new ModelAndView("ftl/login");
    }

    /**
     * 用户信息校验
     * @param authentication 信息
     * @return 用户信息
     */
    @RequestMapping("/user")
    public Object user(Authentication authentication) {
        return authentication.getPrincipal();
    }

    /**
     * 清除Redis中 accesstoken refreshtoken
     *
     * @param accesstoken  accesstoken
     * @return true/false
     */
    @PostMapping("/removeToken")
    @CacheEvict(value = SecurityConstants.TOKEN_USER_DETAIL, key = "#accesstoken")
    public R<Boolean> removeToken(String accesstoken) {
        return new R<>( consumerTokenServices.revokeToken(accesstoken));
    }
}

接口层有三个接口路径,第一个应该没用,剩下两个是校验用户信息的/user和清除Redis中 accesstoken 与refreshtoken的/removeToken

框架配置

框架配置

下面这段代码时配置各种spring security配置,包括登陆界面url是"/authentication/require"啦。如果不使用默认的弹出框而使用自己的页面,表单的action是"/authentication/form"啦。使用自己定义的过滤规则啦。禁用csrf啦(自行搜索csrf,jwt验证不需要防跨域,但是需要使用xss过滤)。使用手机登陆配置啦。

@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER - 1)
@Configuration
@EnableWebSecurity
public class PigSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {
    @Autowired
    private FilterIgnorePropertiesConfig filterIgnorePropertiesConfig;
    @Autowired
    private MobileSecurityConfigurer mobileSecurityConfigurer;

    @Override
    public void configure(HttpSecurity http) throws Exception {
        ExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry registry =
                http.formLogin().loginPage("/authentication/require")
                        .loginProcessingUrl("/authentication/form")
                        .and()
                        .authorizeRequests();
        filterIgnorePropertiesConfig.getUrls().forEach(url -> registry.antMatchers(url).permitAll());
        registry.anyRequest().authenticated()
                .and()
                .csrf().disable();
        http.apply(mobileSecurityConfigurer);
    }
}

校验用户信息

读配置类和接口层,我们知道了,总的逻辑大概就是用户登陆了以后,使用spring security框架的认证来获取权限。

我们一步一步看,边猜想边来。接口处有"ftl/login",这大概就是使用freemarker模板,login信息携带的token会传到用户信息校验url"/user"上,可作者直接使用Authentication返回一个getPrincipal(),就没了,根本没看见自定义的代码,这是怎么回事呢?

原来,作者使用spring security框架,使用框架来实现校验信息。

打卡config包下的PigAuthorizationConfig,我们来一探究竟。

使用spring security 实现 授权服务器

注明,阅读此处模块需要OAUTH基础,https://blog.tengshe789.tech/2018/12/02/感性认识jwt/#more

这里简单提一下,spring security oauth里有两个概念,授权服务器和资源服务器。

授权服务器是根据授权许可给访问的客户端发放access token令牌的,提供认证、授权服务;

资源服务器需要验证这个access token,客户端才能访问对应服务。

客户详细信息服务配置

ClientDetailsServiceConfigurer(AuthorizationServerConfigurer 的一个回调配置项) 能够使用内存或者JDBC来实现客户端详情服务(ClientDetailsService),Spring Security OAuth2的配置方法是编写@Configuration类继承AuthorizationServerConfigurerAdapter,然后重写void configure(ClientDetailsServiceConfigurer clients)方法

下面代码主要逻辑是,使用spring security框架封装的简单sql连接器,查询客户端的详细信息?

	@Override
    public void configure(` clients) throws Exception {
        JdbcClientDetailsService clientDetailsService = new JdbcClientDetailsService(dataSource);
        clientDetailsService.setSelectClientDetailsSql(SecurityConstants.DEFAULT_SELECT_STATEMENT);
        clientDetailsService.setFindClientDetailsSql(SecurityConstants.DEFAULT_FIND_STATEMENT);
        clients.withClientDetails(clientDetailsService);
    }

相关的sql语句如下,由于耦合度较大,我将sql声明语句改了一改,方面阅读:

 /**
     * 默认的查询语句
     */
    String DEFAULT_FIND_STATEMENT = "select " + "client_id, client_secret, resource_ids, scope, "
            + "authorized_grant_types, web_server_redirect_uri, authorities, access_token_validity, "
            + "refresh_token_validity, additional_information, autoapprove"
            + " from sys_oauth_client_details" + " order by client_id";

    /**
     * 按条件client_id 查询
     */
    String DEFAULT_SELECT_STATEMENT = "select " +"client_id, client_secret, resource_ids, scope, "
            + "authorized_grant_types, web_server_redirect_uri, authorities, access_token_validity, "
            + "refresh_token_validity, additional_information, autoapprove"
            + " from sys_oauth_client_details" + " where client_id = ?";

相关数据库信息如下:

服务网关

授权服务器端点配置器

endpoints参数是什么?所有获取令牌的请求都将会在Spring MVC controller endpoints中进行处理

@Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        //token增强配置
        TokenEnhancerChain tokenEnhancerChain = new TokenEnhancerChain();
        tokenEnhancerChain.setTokenEnhancers(
                Arrays.asList(tokenEnhancer(), jwtAccessTokenConverter()));

        endpoints
                .tokenStore(redisTokenStore())
                .tokenEnhancer(tokenEnhancerChain)
                .authenticationManager(authenticationManager)
                .reuseRefreshTokens(false)
                .userDetailsService(userDetailsService);
    }
token增强器(自定义token信息中携带的信息)

有时候需要额外的信息加到token返回中,这部分也可以自定义,此时我们可以自定义一个TokenEnhancer,来自定义生成token携带的信息。TokenEnhancer接口提供一个 enhance(OAuth2AccessToken var1, OAuth2Authentication var2) 方法,用于对token信息的添加,信息来源于OAuth2Authentication

作者将生成的accessToken中,加上了自己的名字,加上了userId

@Bean
    public TokenEnhancer tokenEnhancer() {
        return (accessToken, authentication) -> {
            final Map<String, Object> additionalInfo = new HashMap<>(2);
            additionalInfo.put("license", SecurityConstants.PIG_LICENSE);
            UserDetailsImpl user = (UserDetailsImpl) authentication.getUserAuthentication().getPrincipal();
            if (user != null) {
                additionalInfo.put("userId", user.getUserId());
            }
            ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(additionalInfo);
            return accessToken;
        };
    }
JWT转换器(自定义token信息中添加的信息)

JWT中,需要在token中携带额外的信息,这样可以在服务之间共享部分用户信息,spring security默认在JWT的token中加入了user_name,如果我们需要额外的信息,需要自定义这部分内容。

JwtAccessTokenConverter是使用JWT替换默认的Token的转换器,而token令牌默认是有签名的,且资源服务器需要验证这个签名。此处的加密及验签包括两种方式:

  • 对称加密

  • 非对称加密(公钥密钥)

对称加密需要授权服务器和资源服务器存储同一key值,而非对称加密可使用密钥加密,暴露公钥给资源服务器验签


    public class PigJwtAccessTokenConverter extends JwtAccessTokenConverter {
    @Override
    public Map<String, ?> convertAccessToken(OAuth2AccessToken token, OAuth2Authentication authentication) {
        Map<String, Object> representation = (Map<String, Object>) super.convertAccessToken(token, authentication);
        representation.put("license", SecurityConstants.PIG_LICENSE);
        return representation;
    }

    @Override
    public OAuth2AccessToken extractAccessToken(String value, Map<String, ?> map) {
        return super.extractAccessToken(value, map);
    }

    @Override
    public OAuth2Authentication extractAuthentication(Map<String, ?> map) {
        return super.extractAuthentication(map);
    }
}
redis与token

使用鉴权的endpoint将加上自己名字的token放入redis,redis连接器用的srping data redis框架

 /**
     * tokenstore 定制化处理
     *
     * @return TokenStore
     * 1. 如果使用的 redis-cluster 模式请使用 PigRedisTokenStore
     * PigRedisTokenStore tokenStore = new PigRedisTokenStore();
     * tokenStore.setRedisTemplate(redisTemplate);
     */
    @Bean
    public TokenStore redisTokenStore() {
        RedisTokenStore tokenStore = new RedisTokenStore(redisConnectionFactory);
        tokenStore.setPrefix(SecurityConstants.PIG_PREFIX);
        return tokenStore;
    }

授权服务器安全配置器

@Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security
                .allowFormAuthenticationForClients()
                .tokenKeyAccess("isAuthenticated()")
                .checkTokenAccess("permitAll()");
    }

自定义实现的手机号 认证服务

接口层

先看接口层,这里和pig-upms-service联动,给了三个路径,用户使用手机号码登陆可通过三个路径发送请求

@FeignClient(name = "pig-upms-service", fallback = UserServiceFallbackImpl.class)
public interface UserService {
    /**
     * 通过用户名查询用户、角色信息
     *
     * @param username 用户名
     * @return UserVo
     */
    @GetMapping("/user/findUserByUsername/{username}")
    UserVO findUserByUsername(@PathVariable("username") String username);

    /**
     * 通过手机号查询用户、角色信息
     *
     * @param mobile 手机号
     * @return UserVo
     */
    @GetMapping("/user/findUserByMobile/{mobile}")
    UserVO findUserByMobile(@PathVariable("mobile") String mobile);

    /**
     * 根据OpenId查询用户信息
     * @param openId openId
     * @return UserVo
     */
    @GetMapping("/user/findUserByOpenId/{openId}")
    UserVO findUserByOpenId(@PathVariable("openId") String openId);
}

配置类

重写SecurityConfigurerAdapter的方法,通过http请求,找出有关手机号的token,用token找出相关用户的信息,已Authentication方式保存。拿到信息后,使用过滤器验证

@Component
public class MobileSecurityConfigurer extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {
    @Autowired
    private AuthenticationSuccessHandler mobileLoginSuccessHandler;
    @Autowired
    private UserService userService;

    @Override
    public void configure(HttpSecurity http) throws Exception {
        MobileAuthenticationFilter mobileAuthenticationFilter = new MobileAuthenticationFilter();
        mobileAuthenticationFilter.setAuthenticationManager(http.getSharedObject(AuthenticationManager.class));
        mobileAuthenticationFilter.setAuthenticationSuccessHandler(mobileLoginSuccessHandler);

        MobileAuthenticationProvider mobileAuthenticationProvider = new MobileAuthenticationProvider();
        mobileAuthenticationProvider.setUserService(userService);
        http.authenticationProvider(mobileAuthenticationProvider)
                .addFilterAfter(mobileAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
    }
}

手机号登录校验逻辑MobileAuthenticationProvider

spring security 中,AuthenticationManage管理一系列的AuthenticationProvider
而每一个Provider都会通UserDetailsServiceUserDetail来返回一个
MobileAuthenticationToken实现的带用户以及权限的Authentication

此处逻辑是,通过UserService查找已有用户的手机号码,生成对应的UserDetails,使用UserDetails生成手机验证Authentication

@Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        MobileAuthenticationToken mobileAuthenticationToken = (MobileAuthenticationToken) authentication;
        UserVO userVo = userService.findUserByMobile((String) mobileAuthenticationToken.getPrincipal());

        if (userVo == null) {
            throw new UsernameNotFoundException("手机号不存在:" + mobileAuthenticationToken.getPrincipal());
        }

        UserDetailsImpl userDetails = buildUserDeatils(userVo);

        MobileAuthenticationToken authenticationToken = new MobileAuthenticationToken(userDetails, userDetails.getAuthorities());
        authenticationToken.setDetails(mobileAuthenticationToken.getDetails());
        return authenticationToken;
    }

    private UserDetailsImpl buildUserDeatils(UserVO userVo) {
        return new UserDetailsImpl(userVo);
    }

    @Override
    public boolean supports(Class<?> authentication) {
        return MobileAuthenticationToken.class.isAssignableFrom(authentication);
    }
手机号登录令牌类MobileAuthenticationToken

MobileAuthenticationToken继承AbstractAuthenticationToken实现Authentication
所以当在页面中输入手机之后首先会进入到MobileAuthenticationToken验证(Authentication),
然后生成的Authentication会被交由我上面说的AuthenticationManager来进行管理

public class MobileAuthenticationToken extends AbstractAuthenticationToken {

    private static final long serialVersionUID = SpringSecurityCoreVersion.SERIAL_VERSION_UID;

    private final Object principal;

    public MobileAuthenticationToken(String mobile) {
        super(null);
        this.principal = mobile;
        setAuthenticated(false);
    }

    public MobileAuthenticationToken(Object principal,
                                     Collection<? extends GrantedAuthority> authorities) {
        super(authorities);
        this.principal = principal;
        super.setAuthenticated(true);
    }

    @Override
    public Object getPrincipal() {
        return this.principal;
    }

    @Override
    public Object getCredentials() {
        return null;
    }

    @Override
    public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {
        if (isAuthenticated) {
            throw new IllegalArgumentException(
                    "Cannot set this token to trusted - use constructor which takes a GrantedAuthority list instead");
        }

        super.setAuthenticated(false);
    }

    @Override
    public void eraseCredentials() {
        super.eraseCredentials();
    }
}

手机号登录验证filter

判断http请求是否是post,不是则返回错误。

根据request请求拿到moblie信息,使用moblie信息返回手机号码登陆成功的oauth token。

@Override
    public Authentication attemptAuthentication(HttpServletRequest request,
                                                HttpServletResponse response) throws AuthenticationException {
        if (postOnly && !request.getMethod().equals(HttpMethod.POST.name())) {
            throw new AuthenticationServiceException(
                    "Authentication method not supported: " + request.getMethod());
        }

        String mobile = obtainMobile(request);

        if (mobile == null) {
            mobile = "";
        }

        mobile = mobile.trim();

        MobileAuthenticationToken mobileAuthenticationToken = new MobileAuthenticationToken(mobile);

        setDetails(request, mobileAuthenticationToken);

        return this.getAuthenticationManager().authenticate(mobileAuthenticationToken);
    }

手机登陆成功的处理器MobileLoginSuccessHandler

这个处理器可以返回手机号登录成功的oauth token,但是要将oauth token传输出去必须配合上面的手机号登录验证filter

逻辑都在注释中

@Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) {
        String header = request.getHeader("Authorization");

        if (header == null || !header.startsWith(BASIC_)) {
            throw new UnapprovedClientAuthenticationException("请求头中client信息为空");
        }

        try {
            String[] tokens = AuthUtils.extractAndDecodeHeader(header);
            assert tokens.length == 2;
            String clientId = tokens[0];

            ClientDetails clientDetails = clientDetailsService.loadClientByClientId(clientId);

            //校验secret
            if (!clientDetails.getClientSecret().equals(tokens[1])) {
                throw new InvalidClientException("Given client ID does not match authenticated client");
            }

            TokenRequest tokenRequest = new TokenRequest(MapUtil.newHashMap(), clientId, clientDetails.getScope(), "mobile");

            //校验scope
            new DefaultOAuth2RequestValidator().validateScope(tokenRequest, clientDetails);
            OAuth2Request oAuth2Request = tokenRequest.createOAuth2Request(clientDetails);
            OAuth2Authentication oAuth2Authentication = new OAuth2Authentication(oAuth2Request, authentication);
            OAuth2AccessToken oAuth2AccessToken = authorizationServerTokenServices.createAccessToken(oAuth2Authentication);
            log.info("获取token 成功:{}", oAuth2AccessToken.getValue());

            response.setCharacterEncoding(CommonConstant.UTF8);
            response.setContentType(CommonConstant.CONTENT_TYPE);
            PrintWriter printWriter = response.getWriter();
            printWriter.append(objectMapper.writeValueAsString(oAuth2AccessToken));
        } catch (IOException e) {
            throw new BadCredentialsException(
                    "Failed to decode basic authentication token");
        }
    }

    public static String[] extractAndDecodeHeader(String header)
            throws IOException {

        byte[] base64Token = header.substring(6).getBytes("UTF-8");
        byte[] decoded;
        try {
            decoded = Base64.decode(base64Token);
        } catch (IllegalArgumentException e) {
            throw new CheckedException(
                    "Failed to decode basic authentication token");
        }

        String token = new String(decoded, CommonConstant.UTF8);

        int delim = token.indexOf(":");

        if (delim == -1) {
            throw new CheckedException("Invalid basic authentication token");
        }
        return new String[]{token.substring(0, delim), token.substring(delim + 1)};
    }

服务网关模块

网关主体在包pig\pig-gateway\src\main\java\com\github\pig\gateway

服务网关

作者使用了Zuul做为网关,它Netflix开源的微服务网关,可以和Eureka,Ribbon,Hystrix等组件配合使用。

Zuul组件的核心是一系列的过滤器,这些过滤器可以完成以下功能:

  • 身份认证和安全: 识别每一个资源的验证要求,并拒绝那些不符的请求

  • 审查与监控:

  • 动态路由:动态将请求路由到不同后端集群

  • 压力测试:逐渐增加指向集群的流量,以了解性能

  • 负载分配:为每一种负载类型分配对应容量,并弃用超出限定值的请求

  • 静态响应处理:边缘位置进行响应,避免转发到内部集群

  • 多区域弹性:跨域AWS Region进行请求路由,旨在实现ELB(ElasticLoad Balancing)使用多样化

多种功能的过滤器过滤器

Zuul组件的核心是一系列的过滤器,我们先从过滤器下手。

网关统一异常过滤器

@Component
public class ErrorHandlerFilter extends ZuulFilter {
    @Autowired
    private LogSendService logSendService;
    @Override
    public String filterType() {
        return ERROR_TYPE;
    }
    @Override
    public int filterOrder() {
        return SEND_RESPONSE_FILTER_ORDER + 1;
    }
    @Override
    public boolean shouldFilter() {
        RequestContext requestContext = RequestContext.getCurrentContext();
        return requestContext.getThrowable() != null;
    }
    @Override
    public Object run() {
        RequestContext requestContext = RequestContext.getCurrentContext();
        logSendService.send(requestContext);
        return null;
    }
}

作者以原生zuul过滤器为基础加了日志配置,优先级为+1,数字越大优先级越低。

XSS过滤器

public class XssSecurityFilter extends OncePerRequestFilter {
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        XssHttpServletRequestWrapper xssRequest = new XssHttpServletRequestWrapper(request);
        filterChain.doFilter(xssRequest, response);
    }

重写springMVC里面的的确保在一次请求只通过一次filter的类OncePerRequestFilter,添加一条https://gitee.com/renrenio/renren-fast的工具类XssHttpServletRequestWrapper为过滤链条。

@Override
    public ServletInputStream getInputStream() throws IOException {
····略
        //xss过滤
        json = xssEncode(json);
        final ByteArrayInputStream bis = new ByteArrayInputStream(json.getBytes("utf-8"));
        return new ServletInputStream() {
···略
            }
        };
    }

密码过滤器DecodePasswordFilter

此过滤器优先级为+2.每当一个请求不是请求/oauth/token或者/mobile/token这个地址时,都会解析使用aes解码器password

@Override
    public Object run() {
        RequestContext ctx = RequestContext.getCurrentContext();
        Map<String, List<String>> params = ctx.getRequestQueryParams();
        if (params == null) {
            return null;
        }

        List<String> passList = params.get(PASSWORD);
        if (CollUtil.isEmpty(passList)) {
            return null;
        }

        String password = passList.get(0);
        if (StrUtil.isNotBlank(password)) {
            try {
                password = decryptAES(password, key);
            } catch (Exception e) {
                log.error("密码解密失败:{}", password);
            }
            params.put(PASSWORD, CollUtil.newArrayList(password.trim()));
        }
        ctx.setRequestQueryParams(params);
        return null;
    }

校验码过滤器ValidateCodeFilter

逻辑作者都写在注释中了,此处使用了redis做为服务端验证码的缓存

**
     * 是否校验验证码
     * 1. 判断验证码开关是否开启
     * 2. 判断请求是否登录请求
     * 2.1 判断是不是刷新请求(不用单独在建立刷新客户端)
     * 3. 判断终端是否支持
     *
     * @return true/false
     */
    @Override
    public boolean shouldFilter() {
        HttpServletRequest request = RequestContext.getCurrentContext().getRequest();

        if (!StrUtil.containsAnyIgnoreCase(request.getRequestURI(),
                SecurityConstants.OAUTH_TOKEN_URL, SecurityConstants.MOBILE_TOKEN_URL)) {
            return false;
        }

        if (SecurityConstants.REFRESH_TOKEN.equals(request.getParameter(GRANT_TYPE))) {
            return false;
        }

        try {
            String[] clientInfos = AuthUtils.extractAndDecodeHeader(request);
            if (CollUtil.containsAny(filterIgnorePropertiesConfig.getClients(), Arrays.asList(clientInfos))) {
                return false;
            }
        } catch (IOException e) {
            log.error("解析终端信息失败", e);
        }

        return true;
    }

    @Override
    public Object run() {
        try {
            checkCode(RequestContext.getCurrentContext().getRequest());
        } catch (ValidateCodeException e) {
            RequestContext ctx = RequestContext.getCurrentContext();
            R<String> result = new R<>(e);
            result.setCode(478);

            ctx.setResponseStatusCode(478);
            ctx.setSendZuulResponse(false);
            ctx.getResponse().setContentType("application/json;charset=UTF-8");
            ctx.setResponseBody(JSONObject.toJSONString(result));
        }
        return null;
    }

    /**
     * 检查code
     *
     * @param httpServletRequest request
     * @throws ValidateCodeException 验证码校验异常
     */
    private void checkCode(HttpServletRequest httpServletRequest) throws ValidateCodeException {
        String code = httpServletRequest.getParameter("code");
        if (StrUtil.isBlank(code)) {
            throw new ValidateCodeException("请输入验证码");
        }

        String randomStr = httpServletRequest.getParameter("randomStr");
        if (StrUtil.isBlank(randomStr)) {
            randomStr = httpServletRequest.getParameter("mobile");
        }

        String key = SecurityConstants.DEFAULT_CODE_KEY + randomStr;
        if (!redisTemplate.hasKey(key)) {
            throw new ValidateCodeException(EXPIRED_CAPTCHA_ERROR);
        }

        Object codeObj = redisTemplate.opsForValue().get(key);

        if (codeObj == null) {
            throw new ValidateCodeException(EXPIRED_CAPTCHA_ERROR);
        }

        String saveCode = codeObj.toString();
        if (StrUtil.isBlank(saveCode)) {
            redisTemplate.delete(key);
            throw new ValidateCodeException(EXPIRED_CAPTCHA_ERROR);
        }

        if (!StrUtil.equals(saveCode, code)) {
            redisTemplate.delete(key);
            throw new ValidateCodeException("验证码错误,请重新输入");
        }

        redisTemplate.delete(key);
    }

灰度发布

灰度发布,已经不是一个很新的概念了.一个产品,如果需要快速迭代开发上线,又要保证质量,保证刚上线的系统,一旦出现问题那么可以很快的控制影响面,就需要设计一套灰度发布系统.

灰度发布系统的作用在于,可以根据自己的配置,来将用户的流量导到新上线的系统上,来快速验证新的功能修改,而一旦出问题,也可以马上的恢复,简单的说,就是一套A/BTest系统.

初始化

下面是灰度路由初始化类:

@Configuration
@ConditionalOnClass(DiscoveryEnabledNIWSServerList.class)
@AutoConfigureBefore(RibbonClientConfiguration.class)
@ConditionalOnProperty(value = "zuul.ribbon.metadata.enabled")
public class RibbonMetaFilterAutoConfiguration {

    @Bean
    @ConditionalOnMissingBean
    @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
    public ZoneAvoidanceRule metadataAwareRule() {
        return new MetadataCanaryRuleHandler();
    }
}

灰度发布有关过滤器AccessFilter

首先重写filterOrder()方法,使这个过滤器在在RateLimitPreFilter之前运行,不会出现空指针问题。此处优先级FORM_BODY_WRAPPER_FILTER_ORDER-1.

@Component
public class AccessFilter extends ZuulFilter {
    @Value("${zuul.ribbon.metadata.enabled:false}")
    private boolean canary;

    @Override
    public String filterType() {
        return FilterConstants.PRE_TYPE;
    }

    @Override
    public int filterOrder() {
        return FORM_BODY_WRAPPER_FILTER_ORDER - 1;
    }

    @Override
    public boolean shouldFilter() {
        return true;
    }

    @Override
    public Object run() {
        RequestContext requestContext = RequestContext.getCurrentContext();
        String version = requestContext.getRequest().getHeader(SecurityConstants.VERSION);
        if (canary && StrUtil.isNotBlank(version)) {
            RibbonVersionHolder.setContext(version);
        }

        requestContext.set("startTime", System.currentTimeMillis());
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        if (authentication != null) {
            requestContext.addZuulRequestHeader(SecurityConstants.USER_HEADER, authentication.getName());
            requestContext.addZuulRequestHeader(SecurityConstants.ROLE_HEADER, CollectionUtil.join(authentication.getAuthorities(), ","));
        }
        return null;
    }
}

核心方法在run()上,首先受到request请求,拿到他的版本约束信息,然后根据选择添加token

路由微服务断言处理器MetadataCanaryRuleHandler

自定义ribbon路由规则匹配多版本请求,实现灰度发布。复合判断server所在区域的性能和server的可用性选择server,即,使用ZoneAvoidancePredicate和AvailabilityPredicate来判断是否选择某个server,前一个判断判定一个zone的运行性能是否可用,剔除不可用的zone(的所有server),AvailabilityPredicate用于过滤掉连接数过多的Server。

此处逻辑是

  1. eureka metadata (主机名,IP地址,端口号,状态页健康检查等信息,或者通过配置文件自定义元数据)存在版本定义时候进行判断
  2. 不存在 metadata 直接返回true
@Override
    public AbstractServerPredicate getPredicate() {
        return new AbstractServerPredicate() {
            @Override
            public boolean apply(PredicateKey predicateKey) {
                String targetVersion = RibbonVersionHolder.getContext();
                RibbonVersionHolder.clearContext();
                if (StrUtil.isBlank(targetVersion)) {
                    log.debug("客户端未配置目标版本直接路由");
                    return true;
                }

                DiscoveryEnabledServer server = (DiscoveryEnabledServer) predicateKey.getServer();
                final Map<String, String> metadata = server.getInstanceInfo().getMetadata();
                if (StrUtil.isBlank(metadata.get(SecurityConstants.VERSION))) {
                    log.debug("当前微服务{} 未配置版本直接路由");
                    return true;
                }

                if (metadata.get(SecurityConstants.VERSION).equals(targetVersion)) {
                    return true;
                } else {
                    log.debug("当前微服务{} 版本为{},目标版本{} 匹配失败", server.getInstanceInfo().getAppName()
                            , metadata.get(SecurityConstants.VERSION), targetVersion);
                    return false;
                }
            }
        };
    }

        }

        //网关内部异常
        Throwable throwable = requestContext.getThrowable();
        if (throwable != null) {
            log.error("网关异常", throwable);
            sysLog.setException(throwable.getMessage());
        }
        //保存发往MQ(只保存授权)
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

            rabbitTemplate.convertAndSend(MqQueueConstant.LOG_QUEUE, logVo);
        }
    }
}

多维度限流

限流降级处理器ZuulRateLimiterErrorHandler

重写zuul中默认的限流处理器DefaultRateLimiterErrorHandler,使之记录日志内容

@Bean
    public RateLimiterErrorHandler rateLimitErrorHandler() {
        return new DefaultRateLimiterErrorHandler() {
            @Override
            public void handleSaveError(String key, Exception e) {
                log.error("保存key:[{}]异常", key, e);
            }

            @Override
            public void handleFetchError(String key, Exception e) {
                log.error("路由失败:[{}]异常", key);
            }

            @Override
            public void handleError(String msg, Exception e) {
                log.error("限流异常:[{}]", msg, e);
            }
        };
    }

与spring security oAuth方法整合单点登陆

授权拒绝处理器 PigAccessDeniedHandler

重写Srping security oAuth 提供单点登录验证拒绝OAuth2AccessDeniedHandler接口,使用R包装失败信息到PigDeniedException

@Override
    public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException authException) throws IOException, ServletException {
        log.info("授权失败,禁止访问 {}", request.getRequestURI());
        response.setCharacterEncoding(CommonConstant.UTF8);
        response.setContentType(CommonConstant.CONTENT_TYPE);
        R<String> result = new R<>(new PigDeniedException("授权失败,禁止访问"));
        response.setStatus(HttpStatus.SC_FORBIDDEN);
        PrintWriter printWriter = response.getWriter();
        printWriter.append(objectMapper.writeValueAsString(result));
    }

菜单管理

MenuService

@FeignClient(name = "pig-upms-service", fallback = MenuServiceFallbackImpl.class)
public interface MenuService {
    /**
     * 通过角色名查询菜单
     *
     * @param role 角色名称
     * @return 菜单列表
     */
    @GetMapping(value = "/menu/findMenuByRole/{role}")
    Set<MenuVO> findMenuByRole(@PathVariable("role") String role);
}

使用feign连接pig系统的菜单微服务

菜单权限

@Service("permissionService")
public class PermissionServiceImpl implements PermissionService {
    @Autowired
    private MenuService menuService;

    private AntPathMatcher antPathMatcher = new AntPathMatcher();

    @Override
    public boolean hasPermission(HttpServletRequest request, Authentication authentication) {
        //ele-admin options 跨域配置,现在处理是通过前端配置代理,不使用这种方式,存在风险
//        if (HttpMethod.OPTIONS.name().equalsIgnoreCase(request.getMethod())) {
//            return true;
//        }
        Object principal = authentication.getPrincipal();
        List<SimpleGrantedAuthority> authorityList = (List<SimpleGrantedAuthority>) authentication.getAuthorities();
        AtomicBoolean hasPermission = new AtomicBoolean(false);

        if (principal != null) {
            if (CollUtil.isEmpty(authorityList)) {
                log.warn("角色列表为空:{}", authentication.getPrincipal());
                return false;
            }

            Set<MenuVO> urls = new HashSet<>();
            authorityList.stream().filter(authority ->
                    !StrUtil.equals(authority.getAuthority(), "ROLE_USER"))
                    .forEach(authority -> {
                        Set<MenuVO> menuVOSet = menuService.findMenuByRole(authority.getAuthority());
                        CollUtil.addAll(urls, menuVOSet);
                    });

            urls.stream().filter(menu -> StrUtil.isNotEmpty(menu.getUrl())
                    && antPathMatcher.match(menu.getUrl(), request.getRequestURI())
                    && request.getMethod().equalsIgnoreCase(menu.getMethod()))
                    .findFirst().ifPresent(menuVO -> hasPermission.set(true));
        }
        return hasPermission.get();
    }
}

验证码

创建

ValidateCodeController可以找到创建验证码相关代码

/**
     * 创建验证码
     *
     * @param request request
     * @throws Exception
     */
    @GetMapping(SecurityConstants.DEFAULT_VALIDATE_CODE_URL_PREFIX + "/{randomStr}")
    public void createCode(@PathVariable String randomStr, HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        Assert.isBlank(randomStr, "机器码不能为空");
        response.setHeader("Cache-Control", "no-store, no-cache");
        response.setContentType("image/jpeg");
        //生成文字验证码
        String text = producer.createText();
        //生成图片验证码
        BufferedImage image = producer.createImage(text);
        userService.saveImageCode(randomStr, text);
        ServletOutputStream out = response.getOutputStream();
        ImageIO.write(image, "JPEG", out);
        IOUtils.closeQuietly(out);
    }

其中的 producer是使用Kaptcha,下面是配置类

@Configuration
public class KaptchaConfig {

    private static final String KAPTCHA_BORDER = "kaptcha.border";
    private static final String KAPTCHA_TEXTPRODUCER_FONT_COLOR = "kaptcha.textproducer.font.color";
    private static final String KAPTCHA_TEXTPRODUCER_CHAR_SPACE = "kaptcha.textproducer.char.space";
    private static final String KAPTCHA_IMAGE_WIDTH = "kaptcha.image.width";
    private static final String KAPTCHA_IMAGE_HEIGHT = "kaptcha.image.height";
    private static final String KAPTCHA_TEXTPRODUCER_CHAR_LENGTH = "kaptcha.textproducer.char.length";
    private static final Object KAPTCHA_IMAGE_FONT_SIZE = "kaptcha.textproducer.font.size";

    @Bean
    public DefaultKaptcha producer() {
        Properties properties = new Properties();
        properties.put(KAPTCHA_BORDER, SecurityConstants.DEFAULT_IMAGE_BORDER);
        properties.put(KAPTCHA_TEXTPRODUCER_FONT_COLOR, SecurityConstants.DEFAULT_COLOR_FONT);
        properties.put(KAPTCHA_TEXTPRODUCER_CHAR_SPACE, SecurityConstants.DEFAULT_CHAR_SPACE);
        properties.put(KAPTCHA_IMAGE_WIDTH, SecurityConstants.DEFAULT_IMAGE_WIDTH);
        properties.put(KAPTCHA_IMAGE_HEIGHT, SecurityConstants.DEFAULT_IMAGE_HEIGHT);
        properties.put(KAPTCHA_IMAGE_FONT_SIZE, SecurityConstants.DEFAULT_IMAGE_FONT_SIZE);
        properties.put(KAPTCHA_TEXTPRODUCER_CHAR_LENGTH, SecurityConstants.DEFAULT_IMAGE_LENGTH);
        Config config = new Config(properties);
        DefaultKaptcha defaultKaptcha = new DefaultKaptcha();
        defaultKaptcha.setConfig(config);
        return defaultKaptcha;
    }
}

发送手机验证码

大体逻辑为,先查询验证码redis缓存,没有缓存则说明验证码缓存没有失效,返回错误。

查到没有验证码,则根据手机号码从数据库获得用户信息,生成一个4位的验证码,使用rabbbitmq队列把短信验证码保存到队列,同时加上手机验证码的redis缓存

/**
     * 发送验证码
     * <p>
     * 1. 先去redis 查询是否 60S内已经发送
     * 2. 未发送: 判断手机号是否存 ? false :产生4位数字  手机号-验证码
     * 3. 发往消息中心-》发送信息
     * 4. 保存redis
     *
     * @param mobile 手机号
     * @return true、false
     */
    @Override
    public R<Boolean> sendSmsCode(String mobile) {
        Object tempCode = redisTemplate.opsForValue().get(SecurityConstants.DEFAULT_CODE_KEY + mobile);
        if (tempCode != null) {
            log.error("用户:{}验证码未失效{}", mobile, tempCode);
            return new R<>(false, "验证码未失效,请失效后再次申请");
        }

        SysUser params = new SysUser();
        params.setPhone(mobile);
        List<SysUser> userList = this.selectList(new EntityWrapper<>(params));

        if (CollectionUtil.isEmpty(userList)) {
            log.error("根据用户手机号{}查询用户为空", mobile);
            return new R<>(false, "手机号不存在");
        }

        String code = RandomUtil.randomNumbers(4);
        JSONObject contextJson = new JSONObject();
        contextJson.put("code", code);
        contextJson.put("product", "Pig4Cloud");
        log.info("短信发送请求消息中心 -> 手机号:{} -> 验证码:{}", mobile, code);
        rabbitTemplate.convertAndSend(MqQueueConstant.MOBILE_CODE_QUEUE,
                new MobileMsgTemplate(
                        mobile,
                        contextJson.toJSONString(),
                        CommonConstant.ALIYUN_SMS,
                        EnumSmsChannelTemplate.LOGIN_NAME_LOGIN.getSignName(),
                        EnumSmsChannelTemplate.LOGIN_NAME_LOGIN.getTemplate()
                ));
        redisTemplate.opsForValue().set(SecurityConstants.DEFAULT_CODE_KEY + mobile, code, SecurityConstants.DEFAULT_IMAGE_EXPIRE, TimeUnit.SECONDS);
        return new R<>(true);
    }

缓存

在部分实现类中,我们看到了作者使用了spring cache相关的注解。现在我们回忆一下相关缓存注解的含义:

服务网关

@Cacheable:用来定义缓存的。常用到是value,key;分别用来指明缓存的名称和方法中参数,对于value你也可以使用cacheName,在查看源代码是我们可以看到:两者是指的同一个东西。

@CacheEvict:用来清理缓存。常用有cacheNames,allEntries(默认值false);分别代表了要清除的缓存名称和是否全部清除(true代表全部清除)。

@CachePut:用来更新缓存,用它来注解的方法都会被执行,执行完后结果被添加到缓存中。该方法不能和@Cacheable同时在同一个方法上使用。

后台跑批定时任务模块

Elastic-Job是ddframe中dd-job的作业模块中分离出来的分布式弹性作业框架。去掉了和dd-job中的监控和ddframe接入规范部分。该项目基于成熟的开源产品Quartz和Zookeeper及其客户端Curator进行二次开发。主要功能如下:

  • 定时任务: 基于成熟的定时任务作业框架Quartz cron表达式执行定时任务。
  • 作业注册中心: 基于Zookeeper和其客户端Curator实现的全局作业注册控制中心。用于注册,控制和协调分布式作业执行。
  • 作业分片: 将一个任务分片成为多个小任务项在多服务器上同时执行。
  • 弹性扩容缩容: 运行中的作业服务器崩溃,或新增加n台作业服务器,作业框架将在下次作业执行前重新分片,不影响当前作业执行。
  • 支持多种作业执行模式: 支持OneOff,Perpetual和SequencePerpetual三种作业模式。
  • 失效转移: 运行中的作业服务器崩溃不会导致重新分片,只会在下次作业启动时分片。启用失效转移功能可以在本次作业执行过程中,监测其他作业服务器空闲,抓取未完成的孤儿分片项执行。
  • 运行时状态收集: 监控作业运行时状态,统计最近一段时间处理的数据成功和失败数量,记录作业上次运行开始时间,结束时间和下次运行时间。
  • **作业停止,恢复和禁用:**用于操作作业启停,并可以禁止某作业运行(上线时常用)。
  • **被错过执行的作业重触发:**自动记录错过执行的作业,并在上次作业完成后自动触发。可参考Quartz的misfire。
  • **多线程快速处理数据:**使用多线程处理抓取到的数据,提升吞吐量。
  • **幂等性:**重复作业任务项判定,不重复执行已运行的作业任务项。由于开启幂等性需要监听作业运行状态,对瞬时反复运行的作业对性能有较大影响。
  • **容错处理:**作业服务器与Zookeeper服务器通信失败则立即停止作业运行,防止作业注册中心将失效的分片分项配给其他作业服务器,而当前作业服务器仍在执行任务,导致重复执行。
  • **Spring支持:**支持spring容器,自定义命名空间,支持占位符。
  • **运维平台:**提供运维界面,可以管理作业和注册中心。

配置

作者直接使用了开源项目的配置,我顺着他的pom文件找到了这家的github,地址如下

https://github.com/xjzrc/elastic-job-lite-spring-boot-starter

工作流作业配置

@ElasticJobConfig(cron = "0 0 0/1 * * ? ", shardingTotalCount = 3, shardingItemParameters = "0=Beijing,1=Shanghai,2=Guangzhou")
public class PigDataflowJob implements DataflowJob<Integer> {


    @Override
    public List<Integer> fetchData(ShardingContext shardingContext) {
        return null;
    }

    @Override
    public void processData(ShardingContext shardingContext, List<Integer> list) {

    }
}

测试代码

@Slf4j
@ElasticJobConfig(cron = "0 0 0/1 * * ?", shardingTotalCount = 3,
        shardingItemParameters = "0=pig1,1=pig2,2=pig3",
        startedTimeoutMilliseconds = 5000L,
        completedTimeoutMilliseconds = 10000L,
        eventTraceRdbDataSource = "dataSource")
public class PigSimpleJob implements SimpleJob {
    /**
     * 业务执行逻辑
     *
     * @param shardingContext 分片信息
     */
    @Override
    public void execute(ShardingContext shardingContext) {
        log.info("shardingContext:{}", shardingContext);
    }
}

开源版对这个支持有限,等到拿到收费版我在做分析。

消息中心

这里的消息中心主要是集成了钉钉服务和阿里大鱼短息服务

钉钉

配置

钉钉是相当简单了,只需要一个webhook信息就够了。

webhook是一种web回调或者http的push API,是向APP或者其他应用提供实时信息的一种方式。Webhook在数据产生时立即发送数据,也就是你能实时收到数据。这一种不同于典型的API,需要用了实时性需要足够快的轮询。这无论是对生产还是对消费者都是高效的,唯一的缺点是初始建立困难。Webhook有时也被称为反向API,因为他提供了API规则,你需要设计要使用的API。Webhook将向你的应用发起http请求,典型的是post请求,应用程序由请求驱动。

@Data
@Configuration
@ConfigurationProperties(prefix = "sms.dingtalk")
public class DingTalkPropertiesConfig {
    /**
     * webhook
     */
    private String webhook;
}

消息模板

/**
 * @author lengleng
 * @date 2018/1/15
 * 钉钉消息模板
 * msgtype : text
 * text : {"content":"服务: pig-upms-service 状态:UP"}
 */
@Data
@ToString
public class DingTalkMsgTemplate implements Serializable {
    private String msgtype;
    private TextBean text;

    public String getMsgtype() {
        return msgtype;
    }

    public void setMsgtype(String msgtype) {
        this.msgtype = msgtype;
    }

    public TextBean getText() {
        return text;
    }

    public void setText(TextBean text) {
        this.text = text;
    }

    public static class TextBean {
        /**
         * content : 服务: pig-upms-service 状态:UP
         */

        private String content;

        public String getContent() {
            return content;
        }

        public void setContent(String content) {
            this.content = content;
        }
    }
}

监听

使用队列时时监听

@Slf4j
@Component
@RabbitListener(queues = MqQueueConstant.DINGTALK_SERVICE_STATUS_CHANGE)
public class DingTalkServiceChangeReceiveListener {
    @Autowired
    private DingTalkMessageHandler dingTalkMessageHandler;

    @RabbitHandler
    public void receive(String text) {
        long startTime = System.currentTimeMillis();
        log.info("消息中心接收到钉钉发送请求-> 内容:{} ", text);
        dingTalkMessageHandler.process(text);
        long useTime = System.currentTimeMillis() - startTime;
        log.info("调用 钉钉网关处理完毕,耗时 {}毫秒", useTime);
    }

资源认证服务器 (单点登陆功能)

由于作者在认证中心使用了spring security oauth框架,所以需要在微服务的客户端实现一个资源认证服务器,来完成SSO需求。

配置

暴露监控信息

@Configuration
@EnableResourceServer
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .anyRequest().authenticated()
                .and()
                .csrf().disable();
    }

}

接口

@EnableOAuth2Sso
@SpringBootApplication
public class PigSsoClientDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(PigSsoClientDemoApplication.class, args);
    }

}

监控模块

springboot admin配置

RemindingNotifier会在应用上线或宕掉的时候发送提醒,也就是把notifications发送给其他的notifier,notifier的实现很有意思,不深究了,从类关系可以知道,我们可以以这么几种方式发送notifications:Pagerduty、Hipchat 、Slack 、Mail、 Reminder

@Configuration
    public static class NotifierConfig {
        @Bean
        @Primary
        public RemindingNotifier remindingNotifier() {
            RemindingNotifier notifier = new RemindingNotifier(filteringNotifier(loggerNotifier()));
            notifier.setReminderPeriod(TimeUnit.SECONDS.toMillis(10));
            return notifier;
        }

        @Scheduled(fixedRate = 1_000L)
        public void remind() {
            remindingNotifier().sendReminders();
        }

        @Bean
        public FilteringNotifier filteringNotifier(Notifier delegate) {
            return new FilteringNotifier(delegate);
        }

        @Bean
        public LoggingNotifier loggerNotifier() {
            return new LoggingNotifier();
        }
    }

短信服务下线通知

继承AbstractStatusChangeNotifier,将短信服务注册到spring boot admin中。

            JSONObject contextJson = new JSONObject();
            contextJson.put("name", event.getApplication().getName());
            contextJson.put("seid", event.getApplication().getId());
            contextJson.put("time", DateUtil.date(event.getTimestamp()).toString());

                rabbitTemplate.convertAndSend(MqQueueConstant.MOBILE_SERVICE_STATUS_CHANGE,
                        new MobileMsgTemplate(
                                CollUtil.join(monitorMobilePropertiesConfig.getMobile().getMobiles(), ","),
                                contextJson.toJSONString(),
                                CommonConstant.ALIYUN_SMS,

                                EnumSmsChannelTemplate.SERVICE_STATUS_CHANGE.getTemplate()
                        ));
            }

            if (monitorMobilePropertiesConfig.getDingTalk().getEnabled()) {
                log.info("开始钉钉通知,内容:{}", text);
                rabbitTemplate.convertAndSend(MqQueueConstant.DINGTALK_SERVICE_STATUS_CHANGE, text);
            }


        } else {
            log.info("Application {} ({}) {}", event.getApplication().getName(),
                    event.getApplication().getId(), event.getType());
