1.项目结构

my-shopping  为父工程
shopping-domain  为子工程，为domain项目，没有启动程序
shopping-service-user 为子工程，需要依赖shopping-domain

shopping-domain，shopping-service-user都要继承父类my-shopping 

 

 2.pom文件配置

打包只需要关注配置文件中的<build> *** </build>内容

如果打包的项目没有<mainClass>运行jar包的主程序</mainClass>，就不用加入<build> *** </build>内容

3.配置文件内容
