2使用

在此文件下配置文件夹名称以及对应表名（此名不可有空格，具体问题见注解1）

点击maven下的包执行工程程序，即可生产想要的工程文件

注解1

报错找不到文件

Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.6:generate (default-cli) on project knmarket-manage: .\src\main\resources\mapper\mall \KMallMapper.xml (系统找不到指定的路径。) -> [Help 1]

在git 下执行启动命令并打印日志（-X）

错误原因为文件名存在空格
