統(tǒng)一回復(fù)：mybatis-generator.xml重新生成Mapper.xml時(shí)把之前的xml刪除再次運(yùn)行
2019-05-08
這個(gè)好像是每一次運(yùn)行mybatis-generator命令時(shí)會(huì)在UserDOMapper.xml和UserPasswordDOMapper.xml中重復(fù)生成resultmap的原因，找到重復(fù)的刪除就好

IllegalArgumentException: Result Maps collection already contains value for com.miaoshaproject.dao.UserDOMapper.BaseResultMap
你看下是不是有 resultMap 的 id 重復(fù)了，復(fù)制之后忘記修改id？
