为什么 jpa 和 hibernate 都有“实体"?和“表"注释? [英] Why jpa and hibernate both have "Entity" and "Table" annotations?

问题描述

我用的是hibernate 3.6，发现有这样的注解:

I use hibernate 3.6, and found there are such annotations:

javax.persistence.Entity
org.hibernate.annotations.Entity

javax.persistence.Table
org.hibernate.annotations.Table

为什么hibernate提供自己的?它是jpa的替代品，还是只是补充?应该(可以)我同时使用它们，例如:

Why hibernate provides its own? Is it a replacement of jpa one, or just a complement? Should(Can) I use them both together, like:

@javax.persistence.Entity
@org.hibernate.annotations.Entity
public class User {}

推荐答案

org.hibernate.annotations.Entity 使用休眠特性扩展 javax.persistence.Entity.

org.hibernate.annotations.Entity extends javax.persistence.Entity with hibernate features.
