JPA的历史 [英] History with JPA

问题描述

我需要以一些棘手的方式保持对实体的更改.所有具有这样结构的实体都有一个HISTORY表 TABLE ATTR VALUE DATE TYPE (插入/更新/删除)

I need to keep change of entities in a little bit tricky fashion. There is one HISTORY table for all entities with structure something like this TABLE ATTR VALUE DATE TYPE(insert/update/delete)

由于我是JPA的新手，所以我不知道如何使用JPA实现这一目标.还是为此目的使用JDBC更好?

As I am quite novice in JPA I don't realize how to achive this using JPA. Or it's better to use JDBC for this purpose?

UPD:JPA实现是EclipseLink

UPD: JPA implementation is EclipseLink

推荐答案

JPA本身对此没有解决方案，因此您必须使用特定于实现的解决方案.

JPA itself does not have a solution for this, so you have to use implementation specific solutions.

对于您的实现，请尝试此，然后选中

For your implementation, try this and check this.
