　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);
} 
}

　　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
