准备：先安装zookeeper，然后进入一下步骤

 

服务端

1.新建 maven项目

2.pom.xml 内容如下

     
         
      
       4.0.0
          
      
       com.demo
          
      
       test
          
      
       1.0-SNAPSHOT
          
              
                   
        
         org.springframework
                    
        
         spring-context
                    
        
         4.2.6.RELEASE
                
               
                   
        
         com.alibaba
                    
        
         dubbo
                    
        
         2.5.3
                
               
                   
        
         com.101tec
                    
        
         zkclient
                    
        
         0.9
                
           
      
     

3.在resource里新建 applicationContext.xml

4.新建IAnimal接口

package com.dubbo.controller;public interface IAnimal {    public  String say();}

5.IAnimal接口的实现

package com.dubbo.controller;import com.dubbo.controller.IAnimal;public class Animal implements IAnimal {    public  String say(){        return  "i am say 1";    }}

6.启动该应用（会注册到zookeeper）

import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test1 {    public static void main(String[] args) throws Exception {        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"applicationContext.xml"});        context.start();        System.out.println(" app run ");        System.in.read(); // 按任意键退出    }}

启动后显示“ app run ” 则表示启动成功

 

客户端

1.新建maven 项目 dubbo-controller

2.pom.xml

3.新建 applicationContext.xml

4.新建dubbo-config.xml

5.新建 spring-mvc.xml

6.新建接口 IAnimal

package com.dubbo.controller;public interface IAnimal {	 public  String say();}

 7.新建MyController
