springboot整合Shiro安全框架，提供身份验证、授权、密码管理、回话管理等！

1.引入Shiro依赖并使用Thymeleaf模版技术进行验证：

<!-- springboot整合Shiro安全框架，提供身份验证、授权、密码管理、回话管理等(1) -->
<dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-spring-boot-web-starter</artifactId><version>1.4.0</version>
</dependency><!-- springboot整合Thymeleaf视图层模版引擎 -->
<!-- springboot整合Shiro安全框架，提供身份验证、授权、密码管理、回话管理等(2) -->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<!-- springboot整合Shiro安全框架，提供身份验证、授权、密码管理、回话管理等(3)为了能在Thymeleaf中使用shiro标签，引入依赖 -->
<dependency><groupId>com.github.theborakompanioni</groupId><artifactId>thymeleaf-extras-shiro</artifactId><version>2.0.0</version>
</dependency>

2.在application.properties配置Shiro基本信息

# springboot整合Shiro安全框架，提供身份验证、授权、密码管理、回话管理等(4)
# 开启Shiro配置，默认为true
shiro.enabled=true
# 开启Shiro Web配置，默认为true
shiro.web.enabled=true
# 登录地址，默认为login.jsp
shiro.loginUrl=/login
# 登录成功地址，默认为/
shiro.successUrl=/index
# 未授权默认跳转地址
shiro.unauthorizedUrl=/unauthorized
# 是否允许通过URL参数实现会话跟踪，如果网站支持Cookie，可以关闭此选项，默认为true
shiro.sessionManager.sessionIdUrlRewretingEnabled=true
# 是否允许通过Cookie实现会话跟踪，默认为true
shiro.sessionManager.sessionIdCookieEnabled=true

3.创建ShiroConfig.java，提供用户信息和权限设置

package com.steno.propertiestest.common;import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import org.apache.shiro.realm.Realm;
import org.apache.shiro.realm.text.TextConfigurationRealm;
import org.apache.shiro.spring.web.config.DefaultShiroFilterChainDefinition;
import org.apache.shiro.spring.web.config.ShiroFilterChainDefinition;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** springboot整合Shiro安全框架，提供身份验证、授权、密码管理、回话管理等(5)*/
@Configuration
public class ShiroConfig {/*** 配置两个用户，sang/123,admin/123，对应角色user和admin，* 其中user聚优read权限，admin具有read\wirte权限* @return*/@Beanpublic Realm realm(){TextConfigurationRealm realm = new TextConfigurationRealm();realm.setUserDefinitions("sang=123,user\n admin=123,admin");realm.setRoleDefinitions("admin=read,write\n user=read");return realm;}/*** 配置基本的过滤规则：* "/login"：可以匿名访问* "/doLogin"：可以匿名访问* "/logout"：注销登录请求* "/**"：其余请求都需要认证后才能访问* @return*/@Beanpublic ShiroFilterChainDefinition shiroFilterChainDefinition(){DefaultShiroFilterChainDefinition chainDefinition = new DefaultShiroFilterChainDefinition();chainDefinition.addPathDefinition("/login", "anon");chainDefinition.addPathDefinition("/doLogin", "anon");chainDefinition.addPathDefinition("/logout", "logout");chainDefinition.addPathDefinition("/**", "authc");return chainDefinition;}/*** 为了支持Thymeleaf中使用shiro标签，增加shiroDialect，如果不需要则可以不提供* @return*/@Beanpublic ShiroDialect shiroDialect(){return new ShiroDialect();}
}

4.配置登录访问接口和页面信息
(1)Controller

package com.steno.propertiestest.controller;import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authz.annotation.Logical;
import org.apache.shiro.authz.annotation.RequiresRoles;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;/*** springboot整合Shiro安全框架，提供身份验证、授权、密码管理、回话管理等(6)*/
@Controller
public class UserController {/*** 登录验证(使用UsernamePasswordToken和subject)* @param username* @param password* @param model* @return*/@PostMapping("/doLogin")public String doLogin(String username, String password, Model model){UsernamePasswordToken token = new UsernamePasswordToken(username, password);Subject subject = SecurityUtils.getSubject();try {subject.login(token);} catch (AuthenticationException e) {model.addAttribute("error", "用户名或密码错误！");return "login";}return "redirect:/index";}/*** admin角色可访问的方法* @return*/@RequiresRoles("admin")@GetMapping("/admin")public String admin(){return "admin";}/*** admin或者user角色可访问的方法* @return*/@RequiresRoles(value = {"admin", "user"}, logical = Logical.OR)@GetMapping("/user")public String user(){return "user";}}

(2)配置不需要角色即可访问的接口设置：

package com.steno.propertiestest.common;import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;@Configuration
public class MyWebMVCConfig implements WebMvcConfigurer {@Overridepublic void addResourceHandlers(ResourceHandlerRegistry registry) {System.out.println("==========静态资源拦截！============");//将所有/static/** 访问都映射到classpath:/static/ 目录下registry.addResourceHandler("/static/**/").addResourceLocations("classpath:/static/");}/*** springboot整合Shiro安全框架，提供身份验证、授权、密码管理、回话管理等(7)* 设置不需要角色就可访问的接口* @param registry*/@Overridepublic void addViewControllers(ViewControllerRegistry registry) {registry.addViewController("/login").setViewName("login");registry.addViewController("/index").setViewName("index");registry.addViewController("/unauthorized").setViewName("unauthorized");}
}

(3)创建全局异常处理Controller

package com.steno.propertiestest.common;import org.apache.shiro.authz.AuthorizationException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.servlet.ModelAndView;/*** 全局异常信息处理*/
@ControllerAdvice
public class ExceptionController {/*** 用户访问未授权的资源时，跳转到unauthorized视图，并携带错误信息* @param e* @return*/@ExceptionHandler(AuthorizationException.class)public ModelAndView error(AuthorizationException e){ModelAndView modelAndView = new ModelAndView("unauthorized");modelAndView.addObject("error", e.getMessage());return modelAndView;}
}

(4)创建页面信息：
I、创建登录页面login.html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head><meta charset="UTF-8"><title>登录页面</title>
</head>
<body><form action="/doLogin" method="post"><input type="text" name="username" placeholder="用户名"><br><input type="password" name="password" placeholder="密码"><br><div th:text="${error}"></div><input type="submit" value="登录"></form>
</body>
</html>

II、登录成功后展示页面index.html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org"xmlns:shiro="http://www.pollix.at/thymeleaf/shiro">
<head><meta charset="UTF-8"><title>登录成功后的页面</title>
</head>
<body><h3>hello, <shiro:principal/></h3><a href="/logout">注销登录</a><a shiro:hasRole="admin" href="/admin">管理员页面</a><a shiro:hasAnyRoles="admin,user" href="/user">普通用户页面</a>
</body>
</html>

III、admin角色成功登录页面展示

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>管理员信息展示页面</title>
</head>
<body><h1>管理员信息展示页面</h1>
</body>
</html>

IIII、user角色成功登录页面展示

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>普通的用户信息展示页面</title>
</head>
<body><h1>普通的用户信息展示页面</h1>
</body>
</html>

IIIII、无权限访问的页面展示

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head><meta charset="UTF-8"><title>Shiro授权失败的展示页面</title>
</head>
<body><h3>未获授权，非法访问</h3><h3 th:text="${error}"></h3>
</body>
</html>

5.测试访问
(1)登录
http://localhost:8081/login

(2)admin角色登录展示http://localhost:8081/index

进入管理员页面http://localhost:8081/admin

进入普通用户页面http://localhost:8081/user

(3)user角色登录展示http://localhost:8081/index

进入普通用户页面http://localhost:8081/user

无授权访问展示(即user用户访问admin页面)http://localhost:8081/admin
