Spring Boot整合Dubbo框架demo

Dubbo框架原理见之前的博文：http://www.cnblogs.com/umgsai/p/5836925.html

首先启动zookeeper

Server端

Pom配置如下

发布服务配置

<?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:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd
            http://code.alibabatech.com/schema/dubbo
            http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <!-- 提供方应用信息，用于计算依赖关系 -->
    <dubbo:application name="demo-provider" />

    <!-- 使用zookeeper注册中心暴露服务地址 -->
    <dubbo:registry protocol="zookeeper" address="localhost:2181" />

    <!-- 用dubbo协议在20880端口暴露服务 -->
    <dubbo:protocol name="dubbo" port="20880" />

    <!-- 用户服务接口 -->
    <dubbo:service interface="com.springboot.demo.UserService" ref="userService" />

    <bean id="userService" class="com.springboot.demo.UserServiceImpl"/>

</beans>

测试接口

public interface UserService {
    public String getUserName();
}

接口实现

public class UserServiceImpl implements UserService {
    public String getUserName() {
        System.out.println("Being invoked");
        return "test user";
    }
}

Spring Boot启动类

@ImportResource("classpath:config/appcontext-*.xml")
@Controller
//@EnableAutoConfiguration
@SpringBootApplication
public class SampleController {

    @RequestMapping("/home")
    @ResponseBody
    String home() {
        return "Hello world";
    }

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

启动Spring Boot即可在zookeeper上注册服务端

Client端

服务配置

<?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:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd
            http://code.alibabatech.com/schema/dubbo
            http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <!--消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 -->
    <dubbo:application name="demo-consumer"/>
    <!--zookeeper注册中心 -->
    <dubbo:registry  protocol="zookeeper" address="localhost:2181" />
    <!--使用multicast广播注册中心暴露的服务地址 -->
    <!--<dubbo:registryaddress="multicast://10.57.41.19:1234" /> -->
    <!-- 生成远程服务代理，可以和本地bean一样使用demoService-->
    <dubbo:reference id="userService" interface="com.springboot.demo.UserService" />

</beans>

接口从API包中引入，通过以上配置，Dubbo即可实例化配置的接口

调用端代码如下

@ImportResource("classpath:appcontext-*.xml")
@Controller
//@EnableAutoConfiguration
@SpringBootApplication
public class MainController extends SpringBootServletInitializer implements EmbeddedServletContainerCustomizer {

    @Autowired
    private UserService userService;

    @RequestMapping("/home")
    @ResponseBody
    public String home() {
        return userService.getUserName();
    }

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(MainController.class);
    }

    //修改启动端口
    @Override
    public void customize(ConfigurableEmbeddedServletContainer container) {
        container.setPort(8081);
    }
}

通过访问http://localhost:8081/home即可调用服务端的方法。
