как я получаю только два атрибута моего класса

/ 05 марта 2020

У меня проблема с контроллером, он возвращает весь пользовательский экземпляр, а мне нужно только вернуть атрибут: «email» и «пароль».

Проблема существует в методе public String login () в классе Controller AuthController (вы найдете комментарий, упоминающий его в правой строке)

Controller

    @Autowired
    public UserRepository userRepository;

    @GetMapping(value = {"/signup"})
    public String signup(Model model) {
        model.addAttribute("user", new User());
        return "signup";
    }

    @PostMapping(value = {"/signup"})
    @Transactional
    public String signup(@Valid User user, BindingResult result, Model model, HttpSession session) throws Exception {
        if (result.hasErrors()) {

            return "signup";

Вы можете создать UserDTO следующим образом: 

class UserDTO{
    String email;
    String password;
    public UserDTO(String email, String password) {
        this.email = email;
        this.password = password;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

Затем 

public String login(@Valid User user, BindingResult result, Model model, HttpSession session) throws Exception {
    if (result.hasErrors()) {
        UserDTO userDTO = new UserDTO(user.getEmail(), user.getPassword());
        model.addAttribute("user", userDTO);
    }
}

Я создаю новый пакет DTO и создаю новый класс, называемый Login. Это работает для меня!

@ Controller 

   @GetMapping(value = {"/login"})
    public String login(Model model, HttpSession session) {
        model.addAttribute("login", new Login());
        return "login";
    }

    @PostMapping(value = {"/login"})
    @Transactional
    public String LoginDto(@Valid Login login, BindingResult result, Model model, HttpSession session) throws Exception {
        if (result.hasErrors()) {
            model.addAttribute("login", login);
            return "login";
        } else {
            List<User> userEmail = userRepository.findAll().stream()
                    .filter(u -> u.getEmail().equals(login.getEmail()))
                    .collect(Collectors.toList());
            if (userEmail.isEmpty()) {
                result.rejectValue("email", "error.user", "El email no esta registrado");
                model.addAttribute("login", login);
                return "login";
            }
        }
        return "login";
    }
