What is difference between CrudRepository and JpaRepository interfaces in Spring Data JPA?

Question

What is the difference between `CrudRepository` and `JpaRepository` interfaces in Spring Data JPA? When I see the examples on the web, I see them there used kind of interchangeably. What is the difference between them? Why would you want to use one over the other?

Answer 1

JpaRepository extends PagingAndSortingRepository that extends CrudRepository.

CrudRepository mainly provides CRUD operations.

PagingAndSortingRepository provide methods to perform pagination and sorting of records.

JpaRepository provides JPA related methods such as flushing the persistence context and deleting of records in batch.

Due to their inheritance nature, JpaRepository will have all the behaviors of CrudRepository and PagingAndSortingRepository. So if you don't need the repository to have the functions provided by JpaRepository and PagingAndSortingRepository , use CrudRepository.
