dubbo是一个分布式服务框架，致力于提供高性能和透明化的RPC远程服务调用方案，是阿里巴巴SOA服务化治理方案的核心框架，每天为2,000+个服务提供3,000,000,000+次访问量支持，并被广泛应用于阿里巴巴集团的各成员站点（其他的详细介绍可以查看dubbo的官网地址http://dubbo.io/，写的很详细！）。

该demo是基于maven搭建的，项目架构基于SpringMVC，这里忽略spring的基本配置，着重介绍下dubbo部分的配置，以及dubbo后台管理系统

一、软件环境 
1、zookeeper 
下载地址：https://zookeeper.apache.org/releases.html 下载最新版的zookeeper，我这里使用的版本是 zookeeper-3.4.5.tar.gz 
2、springMVC （maven方式引入） 
3、dubbo （maven方式引入）

二、项目搭建 
这里我搭建了三个项目，分别为dubbo-api，dubbo-consumer，dubbo-provider

dubbo-api：主要是接口定义，供dubbo-consumer调用，以及dubbo-provider的service层去实现该接口，分离这一层的好处就是前端项目调用接口时候，直接调用dubbo-api的接口即可，不需要关注后端如何实现；而service层来具体实现该接口，进行业务逻辑处理，不需要关注dubbo-consumer 的controller层如何调用。

dubbo-consumer：主要controller层控制跳转等。

dubbo-provider：主要是service实现，结合数据层实现后端业务逻辑处理。

项目搭建完成之后，的结构图如下：

三、项目配置 
1、dubbo-api

Maven配置：

新建TestService接口类

package com.dubbo.service;

/**

* dubbo学习地址：http://blog.csdn.net/aixiaoyang168/article/details/51362675

*/

public interface TestService {

/**

* 测试发消息

* @param name

* @return

*/

public String sayHello(String name);

}

注意：这个项目最终打包成jar文件，直接maven引入到另外两个项目中

新建TestServiceImpl类

package com.dubbo.service.impl;

import com.dubbo.service.TestService;

public class TestServiceImpl implements TestService {

public String sayHello(String name) {

return name + " service2 say hello word service2!";

}

}

注意：这里作为服务提供者名称为test_provider，注释很详细，就不一一介绍了，这个项目最终打包成dubbo-service.war放在tomcat或其他容器中运行

好了，经过这么配置之后，我们的项目编码配置部分就大功告成了!

maven编译下三个项目，将dubbo-provider和dubbo-consumer放到tomcat容器中，启动tomcat容器！ 注意此过程中要配置启动zookeeper，不然dubbo去zookeeper注册中心暴露服务地址不成功啦！

四、配置启动zookeeper

最后要启动zookeeper，关于zookeeper的安装配置，可以参考：http://blog.csdn.net/tototuzuoquan/article/details/54003140

启动zookeeper !

再次启动tomcat容器，是不是就成功啦！我们来访问下http://127.0.0.1:8080/dubbo-consumer/test.action?name=toto，看下返回结果是不是正确啦！
