Answer 1

If you describe a field as criteria in method definition ("findBy"), You must pass that parameter to the method, otherwise you will get "Unsatisfied dependency expressed through method parameter" exception.

public interface ClientRepository extends JpaRepository {
       Client findByClientId();                ////WRONG !!!!
       Client findByClientId(int clientId);    /// CORRECT 
}

*I assume that your Client entity has clientId attribute.
