问题描述
我将Spring Hibernate与HibernateSupportDao一起使用，当我尝试发送多行数据以存储在我的数据库中时，它在特定行上引发了DataIntegrityViolationException.相同的方案在保留在同一表的任务中起作用.即使我为当前任务使用相同的代码，我也没有遇到问题.为什么会抛出DataIntegrityViolationException，我该如何纠正?
I am using Spring Hibernate with HibernateSupportDao, when I try to send multiple rows of data to store in my db, it raises a DataIntegrityViolationException at a particular row. The same scenario has worked in remain in task on the same table. I do not get the problem even when I use the same code for the current task. Why was a DataIntegrityViolationException thrown and how can I rectify that?
推荐答案
直接从API :
基本上，这意味着休眠尝试执行某些操作，但是数据库引发了异常.最常见的情况是您要删除父级，而不是删除具有该父级外键的子级.
Basically it means that hibernate tried to do something, but the database raised an exception. Most common case might be that you are deleting a parent but not deleting a child with a foreign key to that parent.
您的传递持久性(即级联)设置是什么?
What are your transitive persistence (i.e. cascade) settings?
