四个步骤

1 搭建zookeeper消息中心

2 搭建dubbo服务端代码

3 写dubbo客户端代码

4 dubbo提供的dubbo-admin-2.5.4.war 管理控制台

一，搭建zookeeper

1 下载zookeeper安装文件
zookeeper-3.3.6.tar.gz
这里提供一个百度网盘的下载地址http://pan.baidu.com/s/1gexxfvP

2  执行命令 tar zxvf zookeeper-3.4.6.tar.gz 解压,

3 到 zookeeper-3.3.6/conf 目录下

把zoo_sample.cfg 复制一份为zoo.cfg,作为默认配置文件

4 配置说明

tickTime：这个时间是作为 Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔，也就是每个 tickTime 时间就会发送一个心跳。
dataDir：顾名思义就是 Zookeeper 保存数据的目录，默认情况下，Zookeeper 将写数据的日志文件也保存在这个目录里。
clientPort：这个端口就是客户端连接 Zookeeper 服务器的端口，Zookeeper 会监听这个端口，接受客户端的访问请求。

我的配置: 端口2181是默认配置

5 在zookper-3.3.6/bin目录下执行

./zkServer.sh start 启动zookeeper

6 验证zookeeper是否启动

使用netstat -lpn | grep 2181
如果有端口号, 说明已经启动

二 DubboServer 工程

1，pom.xml

 3,spring和dubbo配置文件

10. </beans>

config.properties

Java代码  

1. #able_zookeeper
2. able_zookeeper=192.168.50.42:2181

4,java代码 一个接口一个实现类

三 DubboClient工程

1，pom.xml和web.xml，config.properties配置文件和DubboServer配置一样

2，增加一个消费者配置文件applicationContext-dubbo-consumer.xml，注：这里需要把服务提供者的jar包打入到客户端，打接口就可以

Xml代码  

1. <strong><?xml version="1.0" encoding="UTF-8"?>
2. <beans xmlns="http://www.springframework.org/schema/beans"
3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
4.     xsi:schemaLocation="http://www.springframework.org/schema/beans
5.         http://www.springframework.org/schema/beans/spring-beans.xsd
6.         http://code.alibabatech.com/schema/dubbo
7.         http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
9.     <dubbo:reference id="demo" interface="com.zhang.service.demo" check="false" protocol="dubbo"/>
10. </beans> </strong>

 3，使用

Java代码  

1. <strong>package com.zhang.contr;
3. import org.springframework.beans.factory.annotation.Autowired;
6. public class test {
7.     @Autowired
8.     private com.zhang.service.demo demo;
10.     public String testD(){
11.         return demo.sayHello();
12.     }
13. }
14. </strong>

四 dubbo-admin-2.5.4.war 管理控制台

    war包下载地址：http://pan.baidu.com/s/1i4xZamD

把这个war包放到tomcat的webapps目录下

1 修改tomcat的端口号不要和其他服务冲突.

2 修改 WEB-INF 下的dubbo.properties文件

3 启动tomcat,访问.
