    Book findOne(Long id);

}

public class BookRepositoryImpl extends SimpleJpaRepository implements BookRepositoryCustom {

    @Inject
    public BookRepositoryImpl(EntityManager entityManager) {
        super(Book.class, entityManager);
    }

    @Cacheable(value = "books", key = "#id")
    public Book findOne(Long id) {
        return super.findOne(id);
    }

}

public interface BookRepository extends JpaRepository, BookRepositoryCustom {

}
