If you wan't create your own repository interface with Integer as a key. You have to difine:

@NoRepositoryBean public interface MyGenericRepo<T> extends JpaRepository<T, Integer> { }

annotation @NoRepositoryBean is needed to avoid creation of Repository implementation. You can read more on https://stackoverflow.com/a/11585811/3058413.

After it you should difive interface for each entity:

public interface PlaceRepository extends MyGenericRepo<Place> { }

Spring data automatically will create implementation of this repostory.
