<!-- 要生成哪些表-->

< table tableName= "t_bug" domainObjectName= "bugDto"

enableCountByExample= "false" enableUpdateByExample= "false"

enableDeleteByExample= "false" enableSelectByExample= "false" selectByExampleQueryId= "false" ></ table >

< table tableName= "t_bug_img" domainObjectName= "bugImgDto"

enableCountByExample= "false" enableUpdateByExample= "false"

enableDeleteByExample= "false" enableSelectByExample= "false" selectByExampleQueryId= "false" ></ table >

< table tableName= "t_project" domainObjectName= "projectDto"

enableCountByExample= "false" enableUpdateByExample= "false"

enableDeleteByExample= "false" enableSelectByExample= "false" selectByExampleQueryId= "false" ></ table >

< table tableName= "t_project_user" domainObjectName= "projectUserDto"

enableCountByExample= "false" enableUpdateByExample= "false"

enableDeleteByExample= "false" enableSelectByExample= "false" selectByExampleQueryId= "false" ></ table >

</ context >

</ generatorConfiguration >

3:运行脚本:进入cmd

成功。 查看文件

也可以通过idea生成
