javax.persistence.Id和org.springframework.data.annotation.Id有什么区别? [英] What's the difference between javax.persistence.Id and org.springframework.data.annotation.Id?

问题描述

我想知道javax.persistence.Id和org.springframework.data.annotation.Id之间是否有区别.

I'd be interested whether there is the difference between javax.persistence.Id and org.springframework.data.annotation.Id.

1. 如果Spring仅为支持JPA注释而创建了该注释，那为什么呢?
2. org.springframework.data.annotation.Id还有其他[附加]用途吗?

1. If Spring has created that annotation only for support the JPA annotation, then why?
2. Does org.springframework.data.annotation.Id have another [additional] purpose?

Spring当前使用

推荐答案

org.springframework.data.annotation.Id来支持其他非关系持久性数据库或框架的映射，这些数据库或框架没有定义的通用持久性API(如JPA).因此，通常在处理其他spring-data项目(例如spring-data-mongodb，spring-data-solr等)时使用.

org.springframework.data.annotation.Id is currently used by Spring to support mapping for other non relational persistence databases or frameworks that do not have a defined common persistence API like JPA. So, it is normally used when dealing with other spring-data projects such as spring-data-mongodb, spring-data-solr, etc.

javax.persistence.Id是JPA为所有实现定义的注释.请记住，JPA仅适用于关系数据的管理.

javax.persistence.Id is the annotation defined by JPA for all its implementations. Have in mind JPA only applies for management of relational data.
