最近在学习dubbo，想着作一些笔记，从来没有在csdn上面写过博客，今天献出第一次，哈哈，直接上代码

一、创建父工程

  <!--统一管理依赖版本-->

    <!-- 连接zookeeper的依赖，我的zookeeper版本是3.4.14，感觉这个jar版本和zookeeper是大概保持一致的，但是引入3.4.14会报错，我试了下，从3.4.13开始就不行了 -->
    <zookeeper.version>3.4.12</zookeeper.version>

  <!--依赖定义-->
  <!--dependencyManagement 定义依赖版本号。子工程直接加依赖即可，不需要再次加版本号，便于统一维护版本号-->
