I have the following code:

@Modifying
@Transactional
@Query(value = "INSERT INTO users(email, password, name) VALUES (?,?,?)", nativeQuery = true)
void insertUserToUsers(String email, String password, String name);

void insertUserToUsers(User user);

Answer 1

Try this

public interface UserRepository extends CrudRepository<User, Integer> {


@Modifying
@Transactional
@Query(value = "INSERT INTO users(email, password, name) VALUES (:#{#user.email},:#{#user.firstname},:#{#user.name})", nativeQuery = true)
void insertUserToUsers(@Param("user") User user);
}

Answer 2

Try this code,

    @Modifying
@Transactional
@Query(value = "INSERT INTO users(email, password, name) VALUES (?,?,?)", nativeQuery = true)
void insertUserToUsers(String email, String password, String name);

default void insertUserToUsers(User user) {
    return insertUserToUsers(user.getEmail(), user.getPassword(), user.getName());
}

Answer 3

Where you use your UserRepository you can use the default method to save user :

ex:

@Service
public class MyService{

 @Autowired
 private UserRepository userRepository ;

 public void example(User user){

  userRepository.save(user)

 }
}

Because CrudRepository give us some default methods , you can check here
