service接口

public interface DoSomeService {
    public String doSome();
}

service实现类

@Service("doSomeService")
public class DoSomeServiceImpl implements DoSomeService {
    @Override
    public String doSome() {
        System.out.println("生产者提供的服务方法");
        return "provider";
    }
}

配置

<context:component-scan base-package="com.dubbo"/>

    <!--声明服务提供方-->
    <dubbo:application name="provider"/>
    <!--注册中心地址-->
    <dubbo:registry address="zookeeper://127.0.0.1:2181"/>
    <!--dubbo服务端口-->
    <dubbo:protocol name="dubbo" port="20880"/>


    <!--服务注册-->
    <dubbo:service interface="com.dubbo.service.DoSomeService" ref="doSomeService"/>

测试类

public class DubboProviderTest {
    public static void main(String[] args) throws IOException {
        //加载配置文件:配置文件中通过SPring将Dubbo服务注册到注册中心当中去
        ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext-provider.xml");

        System.out.println("服务已经发布!!!!!");
        //阻塞

        System.in.read();
    }
}

 消费者

service接口

public interface DoSomeService {
    public String doSome();
}

配置

<context:component-scan base-package="com.dubbo"/>

    <!--声明服务提供方-->
    <dubbo:application name="consumer"/>
    <!--注册中心地址-->
    <dubbo:registry address="zookeeper://127.0.0.1:2181"/>



    <!--服务消费-->
    <dubbo:reference interface="com.dubbo.service.DoSomeService" id="doSomeService"/>

测试类

public class DubboConsumer {
    public static void main(String[] args) {
        ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext-consumer.xml");


        DoSomeService doSomeService = (DoSomeService)ctx.getBean("doSomeService");
        doSomeService.doSome();

        UserService userService = (UserService)ctx.getBean("userService");
        userService.userServicePro();
    }
}
