求解Exception in thread "main" org.hibernate.MappingException这种错的原因？

Exception in thread "main" org.hibernate.MappingException: Repeated column in mapping for entity: com.pb.hibernate.po.Login column: UESERNAME (should be mapped with insert="false" update="false")

以上错误原因是什么啊？

你hibernate里配置的字段与数据弊搭库表租仿拿里的字大埋段没对应好
和UESERNAME 相关的那个字段，检查一下吧
