How to implement triggers in hibernate
提问by Juzer Arsiwala
I want to implement something similar to triggers in hibernate.
我想在休眠中实现类似于触发器的东西。
What I need is when a column in a table attains a specific value, a row should be inserted in another table or some other table should be updated.
我需要的是当表中的列达到特定值时，应在另一个表中插入一行或更新某个其他表。

That's described in Chapter 14. Interceptors and events.
这在第 14 章拦截器和事件中进行了描述。
You can, for example, intercept a post-update event.
例如，您可以拦截更新后事件。
However, using the event system for businessoperations might not be the best idea (they are best used for infrastructure concerns). You should use a higher level layer for that.
但是，将事件系统用于业务操作可能不是最好的主意（它们最适合用于基础设施问题）。您应该为此使用更高级别的图层。
