综合学习SpringBoot+Dubbo+Zookeeper,结合平时用的框架，对常用的框架整合了一下，从框架到后台到前端，如有侵权，请联系删除！

后台框架springboot+mybatis+dubbo+zookeeper+redis+nginx，其中redis做数据缓存，nginx做页面转发，数据库用mysql！首先springboot-mybatis-dubbo-zookeeper目录架构如下：

首先项目外层定义版本等的pom文件如下：

    <modules>
        <!-- 主要放实体、接口、也可以放一些公用的工具类工程-->
      <module>edu-web-common</module>
        <!--  服务提供者工程-->
      <module>edu-web-server</module>
        <!-- 服务消费者工程 -->

   </modules>
   <!--http://blog.csdn.net/shawearn1027/article/details/55098024-->
</project>

edu-web-client下面的Application.java，主要用注解方式加载Bean,而且服务提供者的启动main方法也写在这下面，代码如下：

@MapperScan("com.cn.bee.dao")
@SpringBootApplication
@ImportResource(locations={"dubbo-provider.xml"})
public class Application {/**
     * 1.启动app层的main方法之后,会自动加载bean， @ConfigurationProperties(prefix="spring.datasource")会自动去application.properties
     * 下面以spring.datasource开头的有关数据库连接的配置文件
     * 2.通过注解@MapperScan("com.cn.bee.dao")自动扫描mybatis的mapper文件
     */
   private static volatile boolean running = true;

    private static Logger logger = Logger.getLogger(Application.class);

    //DataSource配置
    @Bean
    @ConfigurationProperties(prefix="spring.datasource")public DataSource dataSource() {return new com.alibaba.druid.pool.DruidDataSource();
    }//提供SqlSeesion
    @Bean
    public SqlSessionFactory sqlSessionFactoryBean() throws Exception {SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        sqlSessionFactoryBean.setDataSource(dataSource());

        PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        // 配置mapper的扫描，找到所有的mapper.xml映射文件
        sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:/mapper/*.xml"));
        // 加载全局的配置文件
        sqlSessionFactoryBean.setConfigLocation(new DefaultResourceLoader().getResource("classpath:mybatis-config.xml"));

        return sqlSessionFactoryBean.getObject();
    }@Bean
    public PlatformTransactionManager transactionManager() {return new DataSourceTransactionManager(dataSource());
    }/**
     * Main 方法启动项
     */
    public static void main(String[] args) {SpringApplication.run(Application.class, args);
        System.out.println("============= APP Start ON SpringBoot Success =============");
        synchronized (Application.class) {while (running) {try {Application.class.wait();
                } catch (Throwable e) {}}}}}

启动edu-web-client的main方法之后,会自动加载bean， @ConfigurationProperties(prefix="spring.datasource")会自动去application.properties下面以spring.datasource开头的有关数据库连接的配置文件，application.properties如下：

spring.datasource.url=jdbc:mysql://localhost:3306/springbootdb?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

dubbo.registry.center=127.0.0.1:2181
dubbo.protocol.port=20885

服务提供者的dubbo-provider.xml，代码如下：

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

        <context:exclude-filter type="annotation"
                                expression="org.springframework.stereotype.Controller" />
    </context:component-scan>

    <dubbo:application name="springBoot-service-provider-app" />
    <!-- Dubbo注册地址 -->

    <dubbo:service interface="com.cn.bee.service.AreaService" ref="areaService" timeout="3000" ></dubbo:service>


</beans>

edu-web-client中其他层次的代码就省略了，有需要可以联系我了解！同时自己本地可以下载一个单机版的zookeeper

edu-web-common：主要放实体、接口、也可以放一些公用的工具类等待。

到了这里，我们的服务已经可以完成了，运行application.Java的main方法，我们可以看到控制台如下，就代表成功了！

然后我们到edu-web-server，主要做服务端

application.properties如下：

platform_context_path=/bee

dubbo.registry.center=127.0.0.1:2181
server.port=9090
#redis服务器
redis_core_database=127.0.0.1_6379
#配置启动项目时，定时任务隔多长时间运行一次
redis_time=60

然后服务消费者代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd  
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd   
        http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <context:annotation-config />
    <dubbo:application name="springboot-service-consumer-app" />
    <dubbo:registry id="springboot-reg" protocol="zookeeper" address="${dubbo.registry.center}" />
    <dubbo:annotation />

    <context:component-scan base-package="com.cn.bee.*">
        <context:include-filter type="annotation"
                                expression="com.alibaba.dubbo.config.annotation.Reference" />
    </context:component-scan>
</beans>  

Controller的代码就省略了！

最后就是到edu-web-server的启动项，你只需要运行这个main方法，项目就可以访问了，Application.java代码如下：

@SpringBootApplication(scanBasePackages="com.cn.bee.controller")
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
@ImportResource(locations = {"dubbo-consumer.xml"})
public class Application{
   private static Logger logger = Logger.getLogger(Application.class);
    public static void main(String[] args)  throws Exception {SpringApplication.run(Application.class, args);
        System.out.println("============= SpringBoot web Start Success =============");
    }
}

@SpringBootApplication(scanBasePackages="com.cn.bee.controller") 括号里面的内容，如果Controller和启动main同一个包下面是不需要指向的，如果要放在不同包下面不加scanBasePackages="com.cn.bee.controller"会报错！

然后我们现在启动Application，如果成功，我们会看到控制台如下：

这时候我们就可以访问试一下，看到返还的如下JSON数据，就证明我们项目跑起来了：

其中Dubbo注册中心的页面如下：
