3. dubbo-client

①ClientMain

package com.jxq.service;import org.springframework.context.support.ClassPathXmlApplicationContext;/** * Created by jiangxingqi on 2017/2/8. */public class ClientMain {    public static void main(String[] args) {        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(                new String[] { "applicationConsumer.xml" });        context.start();        DubboService service = (DubboService) context.getBean("demoService");        System.out.println(service.sayHello("world"));        context.close();    }}

二、联调

启动zookeep

consumer请求server所提供的sayHello接口

1、run ServerMain 启动服务提供方

2、run ClientMain 启动消费方
