CrudRepository
和 JpaRepository
的区别!
原文地址,转载备份
JpaRepository
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.
