[Source] Difference between CrudRepository and JpaRepository in Spring Data JPA

Benefits of using Spring Data JPA CrudRepository and JpaRepository:

Inheriting these interfaces allows Spring to find customized database operation interfaces and generate proxy classes, which can be injected into Spring containers in the future.

You can not write related SQL operations and generate them by proxy classes

They have an inheritance relationship:

PagingAndSortingRepository inherits from CrudRepository
JpaRepository inherits PagingAndSortingRepository

In other words, CrudRepository provides basic additions, deletions, and corrections; PagingAndSortingRepository provides pagination and sorting methods; JpaRepository provides the methods JPA needs.

When using it, you can choose which interface to inherit according to your specific needs.
