　业务：

package com.toov5.dubbo.consumer;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.toov5.api.member.service.MemberService;

public class OderToMemberTest {

   public static void main(String[] args) {

      ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("dubbo-consumer.xml");

      MemberService memberService =  applicationContext.getBean(MemberService.class);

      String resultUser = memberService.getUser(12L);

      System.out.println("调用服务后的返回结果"+resultUser);

}

}

dubbo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://code.alibabatech.com/schema/dubbo

       http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

	<!--定义了提供方应用信息，用于计算依赖关系；在 dubbo-admin 或 dubbo-monitor 会显示这个名字，方便辨识 -->

	<dubbo:application name="demotest-consumer" />

	<!--使用 zookeeper 注册中心暴露服务，注意要先开启 zookeeper -->

	<dubbo:registry address="zookeeper://192.168.91.5:2181" />

	<!-- 用dubbo协议在20880端口暴露服务 -->

	<dubbo:protocol name="dubbo" port="20880" />

	<!--使用 dubbo 协议实现定义好的 MemberService 接口 -->

	<dubbo:reference id="memberService" interface="com.toov5.api.member.service.MemberService"/>

</beans>

　　启动：

只引入了接口没有实现。实现都是通过底层转换成rpc dubbo协议进行调用的
