@Repository
public interface DepartmentRepository extends JpaRepository<Department,Long> {
    Department findByDepartmentId(Long departmentId);
}

In repository the method name should be findByDepartmentId, because , in sql it implements like select * from Department where departmentId = "some number"

Or you can use Optional<Department> findById(Long id) from JpaRepository.

It accepts @Id property.
