Hibernate中的EventType.POST_UPDATE和EventType.POST_COMMIT_UPDATE有什么区别？ [英] What is the difference between the EventType.POST_UPDATE and EventType.POST_COMMIT_UPDATE in Hibernate?

问题描述

这个问题在 Hibernate拦截器和事件监听器
。

以下是我对此的回答。

解决方案

POST_COMMIT_UPDATE 和 POST_UPDATE 是类型 PostUpdateEventListener


1 POST_COMMIT_UPDATE 在数据存储更新后发生。应该使用，如果在事务挂钩之后需要注册。

方法 requiresPostCommitHandling 如果在添加事务回调之后返回true。

这里，是一个示例，其中描述了 POST_COMMIT_UPDATE 。

2）简单 POST_UPDATE 事件是基于hibernate刷新逻辑触发的。

This question was raised in comment section of Hibernate interceptor and event listeners .

Below is my answer on that.

解决方案

The POST_COMMIT_UPDATE and POST_UPDATE are the events of type PostUpdateEventListener that occurs after the datastore is updated.

1) The POST_COMMIT_UPDATE should be used, if after transaction hooks need to be registered.
The method requiresPostCommitHandling returns true if after transaction callbacks should be added.
Here, is an example that depicts the use of POST_COMMIT_UPDATE.

2) The plain POST_UPDATE event is triggered based on hibernate flushing logic.
Here is an example of POST_UPDATE.
