Their main functions are:
CrudRepositorymainly provides CRUD functions.PagingAndSortingRepositoryprovides methods to do pagination and sorting records.JpaRepositoryprovides 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.
