~~~ parent是所有工程的父工程 管理jar文件版本和插件版本 common工具类 manager后台管理的聚合工程 -pojo interface dao service web是manager的模块 ~~~ ## 5.1.Maven（项目构建工具） 使用maven管理工程 1、jar文件管理 2、工程之间的相互引用 3、自动打包构建项目 ## 5.2.后台工程搭建分析 1、maven的打包方式：jar、war、pom 2、父工程：pom，管理jar包的版本，管理插件的版本，统一管理依赖关系。 3、聚合工程：pom。 4、项目结构 buy-parent：父工程，打包方式pom，管理jar包的版本号。     |           项目中所有工程都应该继承父工程。 |--buy-common：通用的工具类通用的pojo（实体类）。打包方式jar
