Spring 数据存储库无需注释即可工作 [英] Spring data repository works without annotations

问题描述

我正在使用 Spring Data JPA 存储库(例如 MyRepo extends JpaRepository)，它在没有 @Repository 和 @EnableJpaRepositories 注释的情况下工作.有人可以解释为什么吗?

I'm using Spring Data JPA repositories (like MyRepo extends JpaRepository) and it works without @Repository and without @EnableJpaRepositories annotations. Could someone explain why?

推荐答案

可能你正在使用 Spring Boot.

Probably you are using Spring Boot.

Spring Data 存储库通常从存储库或CrudRepository 接口.如果您使用自动配置，将从包含您的主要内容的包中搜索存储库配置类(用@EnableAutoConfiguration 注释的那个或@SpringBootApplication)关闭.

Spring Data repositories usually extend from the Repository or CrudRepository interfaces. If you are using auto-configuration, repositories will be searched from the package containing your main configuration class (the one annotated with @EnableAutoConfiguration or @SpringBootApplication) down.

请检查 https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-sql.html#boot-features-spring-data-jpa-repositories 了解更多详情.
