前言
本文中使用的项目是由上一篇文章中的项目改造而来。具体来说，就是引入了dubbo和zookeeper，并将Controller层与service层dao层进行了拆分，使双方通过service接口远程调用的形式，再次实现了基本的增删改查。

名词解释
dubbo：dubbo是阿里开源的一款优秀的java RPC框架，可以配合spring和zookeeper使用。它提供了这些功能：面向接口的远程方法调用，智能容错和负载均衡，以及服务自动注册和发现。
zookeeper：zookeeper 是由雅虎创建的一个开源的分布式协调服务，是Google的Chubby一个开源的实现，是Hadoop和Hbase的重要组件。它提供了这些功能：配置维护、域名服务、分布式同步、组服务等。
