【java小程序实战】小程序短视频项目之springBoot后台搭建

其他 2018-11-30 13:09:03 阅读次数: 0

在以往的项目中我们使用的是单结构工程
在这里插入图片描述
在小程序这个项目中我们会使用maven搭建分层的聚合工程
一个imooc-video工程下，有很多子工程common、mapper、api、pojo等子工程。
一般分为common层其他工程都可以调用，pojo层数据库的实体类，mapper层数据库的映射java文件，service层，这些分层的工程之前可以互相调用。
在这里插入图片描述

我们可以先建一个这样的目录结构mybatis-generatorconfig 是数据库mapper的生成工程，后面会把代码放出来。
在这里插入图片描述

imooc-videos-dev 父工程下的pom文件配置如下：
