在resources文件夹下创建一个配置文件 consumer.xml
内容如下          
<?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: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">
  <!--服务名称 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="order-consumer" />
  <!--向zookeeper订阅provider的地址，由zookeeper定时发送 -->
  <dubbo:registry address="zookeeper://localhost:2181" />
  <!--使用 dubbo 协议调用定义好的 api.PermissionService 接口 -->
  <dubbo:reference id="memberService"
  interface="com.vhukze.api.member.service.MemberService" />
</beans>
创建一个类在com.vhukze.orderTest包下
package com.vhukze.orderTest;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.vhukze.api.member.service.MemberService;
public class OrderToMemberTest {
  public static void main(String[] args) {
  //加载配置文件
  ClassPathXmlApplicationContext app = new ClassPathXmlApplicationContext("consumer.xml");
  //获得对象
  MemberService memberService = app.getBean(MemberService.class);
  //调用方法
  System.out.println("订单服务调用会员服务返回结果："+memberService.getUser(5l));
  }
}
