【java小程式實戰】小程式短視訊專案之springBoot後臺搭建
阿新 • • 發佈：2018-11-30
在以往的專案中我們使用的是單結構工程
在小程式這個專案中我們會使用maven搭建分層的聚合工程
一個imooc-video工程下，有很多子工程common、mapper、api、pojo等子工程。
一般分為common層其他工程都可以呼叫，pojo層資料庫的實體類，mapper層資料庫的對映java檔案，service層，這些分層的工程之前可以互相呼叫。
我們可以先建一個這樣的目錄結構mybatis-generatorconfig 是資料庫mapper的生成工程，後面會把程式碼放出來。
imooc-videos-dev 父工程下的pom檔案配置如下：

各個工程的pom檔案配置就完成了。下面我們需要通過逆向工程生成mapper對映類類，實體類，mapper xml檔案。
