推荐答案

如果你必须通过hibernate加密数据，你可以监听save&通过扩展DefaultSaveOrUpdateListener来更新事件，查看示例
http：/ /www.java2s.com/Code/Java/Hibernate/EventYourOwnSaveOrUpdateEventListener.htm

if you have to encrypt data through hibernate, you can listen to save & update events by extending DefaultSaveOrUpdateListener, check this out for an example http://www.java2s.com/Code/Java/Hibernate/EventYourOwnSaveOrUpdateEventListener.htm

您还需要将配置添加到您的hibernate，cfg，xml文件。

you also need to add the config to your hibernate,cfg,xml file.

<listener class="" type="auto-flush" />

这将听所有保存&更新事件
以侦听对象创建（当您加载数据时）使用DefaultLoadListener
http://www.java2s.com/Open-Source/Java-Document/Database-ORM/hibernate/org/hibernate /event/def/DefaultLoadEventListener.java.htm

this will listen to all save & update events to listen to object creation (when you load data) use the DefaultLoadListener http://www.java2s.com/Open-Source/Java-Document/Database-ORM/hibernate/org/hibernate/event/def/DefaultLoadEventListener.java.htm

请记住，这些事件仅在您使用常规会话时调用（通过调用<$ c $如果使用 session.openStatelessSession（），则c> openSession（）或 getSession >然后这些电话不会发生）

remember, these events are called only when you are using a regular session (by calling openSession() or getSession(), if you use session.openStatelessSession() then these calls do not happen)
