org.springframework.dao.DataIntegrityViolationException: Could not execute JDBC batch update; nested exception is org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update 异常信息 各位大佬 帮我看看 谢谢 这个错误我找了一下午了 没发现代码哪儿出错了啊！
------解决方案--------------------
org.hibernate.exception.ConstraintViolationException
违反约束了，仔细查看数据库提示的报错信息，尤其是主键冲突
