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

In short, the following are the differences between CrudRepository, PagingAndSortingRepository, and JpaRepository:

• CrudRepository: provides CRUD (create, read, update and delete) functions
• PagingAndSortingRepository: provides additional methods to do pagination and sort records
• JpaRepository: provides some more functionality that are JPA related methods such as flushing the persistence context and delete records in a batch
