使用Spring Data JPA CrudRepository 和JpaRepository 的好处： 继承这些接口，可以使Spring找到自定义的数据库操作接口，并生成代理类，后续可以注入到Spring容器中；可以不写相关的sql操作，由代理类生成他们存在继承关系： PagingAndSortingRepository 继承 CrudRepository JpaRepository 继承 PagingAndSortingRepository 也就是说， CrudRepository 提供基本的增删改查； PagingAndSortingRepository 提供分页和排序方法； JpaRepository 提供JPA需要的方法。 extends PagingAndSortingRepository which in turn extends CrudRepository. Their main functions are: CrudRepository mainly provides CRUD functions.PagingAndSortingRepository provides methods to do pagination and sorting records.JpaRepository provides some JPA-related methods such as flushing the persistence context and deleting records in a batch.Because of the inheritance mentioned above, JpaRepository will have all the functions of CrudRepository and PagingAndSortingRepository. So if you don't need the repository to have the functions provided by JpaRepository and PagingAndSortingRepository , use CrudRepository. |
