2.接口及公共模块
该模块是服务端和消费者端都需要用到的公共模块，包括服务接口以及接口所依赖的实体类，当然其他的公共资源也可以放到这个模块中，公共模块的目录结构如下：
实体类
Service接口
生产者
导入依赖
<dependencies>
<!--公共模块导入的依赖-->
<dependency>
<groupId>com.dubbo</groupId>
<artifactId>dubbo_service01_02</artifactId>
<version>1.0-SNAPSHOT</version>
<scope>compile</scope>
</dependency>
</dependencies>
dao接口层
serviceImpl层
在pom.xml文件中带入了接口及公共模块的依赖，所以这里就不需要编写service接口层和实现类
