Spring + Hibernate与Spring Data JPA:它们有区别吗? [英] Spring + hibernate versus Spring Data JPA: Are they different?

问题描述

尽管不是新手，但我还是试图学习spring框架，以确保我真的了解这一点.我对核心Spring(DI)有一个很好的主意.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"春季和冬眠"这个词.据我解释，这意味着将Spring Framework与Hibernate一起用作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 ".我在SO上澄清了有关Spring Data JPA的问题，它是JPA之上的抽象层(Spring Data JPA在后台使用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).

现在这些术语是一样的吗?也就是说，" Spring +休眠"与" Spring Data JPA "相同.如果没有，那么区别/相似之处是什么?

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?

我对如此多的术语/声明(如上)感到很困惑，这些术语/声明看似相似，但可能有所不同.

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提供的功能不只是经典的Spring-JPA集成.借助JPA/Hibernate集成，您可以获得

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/休眠事务的声明式事务管理
• 例外翻译
• 作为可注入bean的JPA EntityManager或Hibernate SessionFactory

使用Spring-data-jpa，您将获得所有这些，加上(除其他外)

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

• 仅接口的存储库，使用方法名称自动推断查询
• @Query注释定义接口方法应返回的查询
• 可分页查询的自动处理
• 标准Crud存储库的基类
