dubbo+zk+springMVC项目搭建

项目基于dubbo-2.6.0 + zk-3.4.10实现

关于dubbo-admin和zk就不说了下面直接开始撸代码。

下图是项目结构
新建maven project 父工程下面是maven库版本依赖

    <!-- 注解包扫描位置: 因为这里的实现类使用注解的方式 -->

    <!-- 用dubbo协议在20880端口暴露服务 -->
    <dubbo:protocol name="dubbo" port="20880" />

    <!--
            声明需要暴露的服务接口，
            请注意ref属性中指定的HelloService接口实现类，它并没有在xml文件中定义，而是使用注解的方式在class中定义

    <dubbo:service interface="com.lxk.demo.service.IService" ref="helloService"/>

运行得到以下结果
至此服务提供者已经完成下面就是服务消费者的实现
