org.hibernate.criteria.uniqueResult期间的AssertionFailure
[英]org.hibernate.AssertionFailure during criteria.uniqueResult
问题描述
I am selecting data from a table which is call pHistory, this table does not have any relationShip with CenterLog entity, however, I am still getting hibernate error complain that null id in CenterLog entity.
我正在从一个名为 pHistory 的表中选择数据，该表与 CenterLog 实体没有任何关系，但是，我仍然收到 hibernate 错误，抱怨 CenterLog 实体中的 null id。
The log is as follow:日志如下：
org.hibernate.AssertionFailure: null id in com.audit.entity.CenterLog entry (don't flush the Session after an exception occurs)

at org.hibernate.impl.CriteriaImpl.uniqueResult(CriteriaImpl.java:328) ~[hibernate-core-3.3.1.GA.jar:3.3.1.GA]
As my understanding, uniqueResult is not doing any save event, but not sure I am still hitting this.据我了解， uniqueResult 没有做任何保存事件，但不确定我是否仍在点击它。

The error message says (don't flush the Session after an exception occurs) : there was another exception earlier and it the cause of the problem.错误消息说(don't flush the Session after an exception occurs) ：之前有另一个异常，它是问题的原因。
You need to find that other exception and fix it.您需要找到其他异常并修复它。
