    问题已经解决,自己在generatorConfig.xml 中配置了两个不同的table,一个不用的table  生成了pojo,mapper以及*mapper.xml,但是项目中没有引用无用的table,所以报错,在  generatorConfig.xml 除去那个无用的table即可。

    除去:

    <table tableName="aaa"></table>

    查看mapper.xml文件是否有有两份对数据库表的重复配置。

    但是即使拟解决了这个地方的问题,按照老师的流程在IDEA里面运行mapperController  还是会出现问题 ,,,,放弃这个老师的教程了  可能差了两年导致有些问题会无法避免的出现。

    com.lm.mapper.TUsersMapper.BaseResultMap 这个mapper.xml文件有问题,检查一下配置的dao接口和mapper文件的引用方法是否都正确。
