解决:org.hibernate.exception.ConstraintViolationException: could not execute statement
来源:互联网 发布:淘宝开店卖食品 编辑:程序博客网 时间:2024/05/26 07:28
今天真的很痛苦!初入几天 Hibernate 框架,下午写了一堆 JUnit 测试,结果基本上全部报错:
org.hibernate.exception.ConstraintViolationException: could not execute statement
其字面意思就是”违反约束异常,无法执行语句”。
百度也没找到什么合适的解决办法,不过就在刚刚,我终于找到了问题出在哪里!
原因在于:你要操作的属性与你数据库中的字段类型不一样,例如:你设置的数据库某字段类型不能为空,而你恰恰把 null 值传了过去(我就是这个原因),当然会报错啊!
解决办法:仔细检查数据库字段与你想要操作的属性有没有互相违反规则的地方,如果有,改正即可!
总结:以后写代码一定要认真认真再认真啊!
