Answer 1

In your UserRepository File

public interface UserRepository extends JpaRepository {
      Boolean existsByEmail(String email);
}

In your controller file

@Autowired
private UserRepository userRepository;

if(userRepository.existsByEmail(pass_email_HERE)) {
        throw new YourCustomExceptionException("CUSTOM_ERROR_MESSAGE");
    }
