Spring + hibernate 与 Spring Data JPA:它们有什么不同吗? [英] Spring + hibernate versus Spring Data JPA: Are they different?

问题描述

虽然不是新手，但我正在尝试学习 spring 框架(再次！)以确保我真的理解这一点.我对核心 Spring (DI) 有了很好的想法.现在，我专注于数据层.

Although not novice, I am trying to learn spring framework (again!) in order to be sure that I really understand this. I have got fair idea on core Spring (DI). Now, I am focusing on Data layer.

我遇到过Spring 和 Hibernate"这个词.正如我所理解的，这意味着使用 Spring Framework 和 Hibernate 作为 ORM 工具/JPA 提供程序.

I have come across the term "Spring and Hibernate". As I can interpret it would mean using Spring Framework with Hibernate as ORM tool/JPA provider.

现在我遇到了Spring Data JPA".我澄清了关于 Spring Data JPA 的 SO，它是 JPA 之上的一个抽象层(并且在底层 Spring Data JPA 使用 Hibernate 或任何其他 JPA 提供程序).

Now I have come across "Spring Data JPA". I clarified on SO about Spring Data JPA, that it is an abstraction layer on-top of JPA (and under the hood Spring Data JPA uses Hibernate or any other JPA provider).

现在这些术语相同吗?即，Spring + hibernate"与Spring Data JPA"相同.如果不是，那么有什么不同/相似之处?

Now are these terms same? That is, is "Spring + hibernate" same as that of "Spring Data JPA". If not, then what is the difference / similarities?

我对这么多看似相似但可能不同的术语/陈述(如上述)感到非常困惑.

I am really confused on so many terms/statements (like above) seemingly to be similar, but may be different.

推荐答案

Spring-data-jpa，正如您所说，提供的不仅仅是经典的 Spring-JPA 集成.通过 JPA/Hibernate 集成，您主要获得

Spring-data-jpa, as you're saying, offers more that just the classical Spring-JPA integration. With JPA/Hibernate integration, you get mainly

• 使用 JPA/Hibernate 事务的声明式事务管理
• 异常翻译
• 作为可注入 bean 的 JPA EntityManager 或 Hibernate SessionFactory

使用 Spring-data-jpa，您可以获得所有这些，以及(除其他外)

With Spring-data-jpa, you get all that, plus (among other things)

• 仅限接口的存储库，使用方法名称自动推断查询
• @Query 注解定义接口方法应该返回的查询
• 自动处理 Pageable 查询
• 标准 crud 存储库的基类
