Mac IDEA Maven插件 MyBatis自動映射生成

前言：

之前用的是windows系統，直接用命令行就搞定了，Mac按照網上各位大佬的教程，一直沒有成功，一直報各種error。最後的最後，選擇了用IDEA集成maven插件，終！於！成！功！了！！！！喜大普奔，我不會說Mac之前都是純手打的PO和Mapper。累死我惹QAQ

說正事：

首先，搭建maven環境，這個就不細說了，參考大佬鏈接，沒有最詳細，只有更詳細。大佬指路

然後就是配置文件啦，主要關注三個：

1.pom.xml 添加各種maven依賴 比如 mybatis mysql

2.generatorConfig.xml myBatis的配置文件，包含了各種配置信息

3.generator.propertities 配置屬性值

前方高能：一定記得放在<pluginManagement>外面，不要問我爲什麼，放裏面試試 就知道了，看看你的mybatis插件還在嗎？（手動滑稽）
