SimpleJpaRepository (Spring Data JPA 1.4.1.RELEASE API)

java.lang.Object
- 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>, CrudRepository<T,ID>, PagingAndSortingRepository<T,ID>, Repository<T,ID>

Direct Known Subclasses:

QueryDslJpaRepository
```
@Repository
@Transactional(readOnly=true)
public class SimpleJpaRepository<T,ID extends Serializable>
extends Object
implements JpaRepository<T,ID>, JpaSpecificationExecutor<T>
```
Default implementation of the CrudRepository interface. This will offer you a more sophisticated interface than the plain EntityManager .
