问题描述

org.hibernate.HibernateException: identifier of an instance

任何想法如何解决它？

in fact, my user table is really must dynamically change its value, my Java app is multithreaded. Any ideas how to fix it?

推荐答案

您是否在某处更改用户对象的主键值？你不应该那样做。检查您的主键映射是否正确。

Are you changing the primary key value of a User object somewhere? You shouldn't do that. Check that your mapping for the primary key is correct.

您的映射XML文件或映射注释是什么样的？

What does your mapping XML file or mapping annotations look like?
