jdbc.properties文件如下

driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/qlm?autoReconnect=true&useUnicode=true&characterEncoding=utf-8
username=root
password=root

运行-->Run As -->Maven build-->Goals填写mybatis-generator:generate--Run

或者 直接运行 mvn mybatis-generator:generate -e

 

根据命令 生成不同环境的 orm包

执行命令 

mvn mybatis-generator:generate -e -P debug
mvn mybatis-generator:generate -e -P pord

 需要注意的是如果 在 setting.xml 里面配置了 默认启动的环境 则 可能会影响 maven 最终的执行结果
