  org.springframework.data.jpa.repository.support.SimpleJpaRepository<T,ID>

Type Parameters:

T - the type of the entity to handle

ID - the type of the entity's identifier

All Implemented Interfaces:

JpaRepository<T,ID>, JpaSpecificationExecutor<T>, org.springframework.data.repository.PagingAndSortingRepository<T,ID>, org.springframework.data.repository.Repository<T,ID>

@Repository
public class SimpleJpaRepository<T,ID extends Serializable>
extends Object
implements JpaRepository<T,ID>, JpaSpecificationExecutor<T>

Default implementation of the Repository interface. This will offer you a more sophisticated interface than the plain EntityManager .
