Как правильно сохранить список телефонов юзера в SpringBoot Java используя thymeleaf?

Question

[den1793]

Всем привет! Пытаюсь сделать базу данных пользователей и столкнулся с проблемой сохранения списка телефонов.

Мой код:
Entity:

@Entity
@Table(name = "users")
@Setter
@Getter
@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
@ToString
public class User implements UserDetails {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(length = 40, name = "name")
    private String name;

    @Column(length = 40, name = "last_name")
    private String lastname;

    @Column(unique = true, length = 250, nullable = false)
    private String username;

    @Column(nullable = false, length = 250)
    private String password;

    @Column(nullable = false, length = 250)
    private String email;

    @OneToMany(cascade = CascadeType.ALL)
    private List<Telephone> telephones = new ArrayList<>();


    private String position;

    @ElementCollection
    @LazyCollection(LazyCollectionOption.FALSE)
    private Set<Role> roles;

@Entity
@Data
@AllArgsConstructor
@NoArgsConstructor
@Getter
@Setter
@Builder
@ToString
public class Telephone {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private String number;


    @Override
    public String toString() {
        return  number;
    }


    @ToString.Exclude
    @ManyToOne
    @JoinColumn(name = "user_id")
    private User user;


}

DTO

@NoArgsConstructor
@AllArgsConstructor
@Builder
@Getter
@Setter
public class UserRegistrationDTO {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long user_id;

    @Size(min = 3, max = 50)
    @Pattern(regexp = "([A-Za-z])*", message = "The firstname contains invalid characters")
    private String name;

    @Size(min = 3, max = 50)
    @Pattern(regexp = "([A-Za-z])*", message = "The lastname contains invalid characters")
    private String lastname;

    @Pattern(regexp = "\\w*", message = "The username contains invalid characters")
    private String username;

    @Pattern(regexp = "^(?=.*[a-z])(?=.*[A-Z])(?=.*\\d)(?=.*[@$!%*?&])[A-Za-z\\d@$!%*?&]{8,}$", message = "The password short or contain invalid characters")
    private String password;

    @Pattern(regexp = "^[\\w-\\.]+@([\\w-]+\\.)+[\\w-]{2,4}$", message = "The email field does not contain a valid email address")
    private String email;

    private List<Telephone> telephones;

    @Size(min = 3, max = 50)
    @Pattern(regexp = "([A-Za-z])*", message = "The position contains invalid characters")
    private String position;

Mapper

@Mapper(componentModel = "spring")
@Component
public interface UserMapper {
    UserMapper INSTANCE = Mappers.getMapper(UserMapper.class);


    UserRegistrationDTO userToDto(User user);
    
    User dtoToUser(UserRegistrationDTO registrationDTO);
}

Service

@Service
public class UserService implements UserDetailsService {

    @Autowired
    private final UserRepository userRepository;

    UserService(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    private final Logger log = Logger.getLogger(UserService.class.getName());

    public boolean save(UserRegistrationDTO userRegistrationDTO) {

        User user = UserMapper.INSTANCE.dtoToUser(userRegistrationDTO);

        user.setRoles(Set.of(Role.ADMIN));
        user.setPassword(passwordEncoder().encode(userRegistrationDTO.getPassword()));

        userRepository.save(user);
        log.log(Level.INFO, "User saved " + userRegistrationDTO.getUsername());
        return true;
    }

Controller

@Controller
@RequestMapping("/user")
public class UserController {
    @Autowired
    private UserService userService;

    @GetMapping("/registration")
    public String registration(Model model) {
        model.addAttribute("newUser", new UserRegistrationDTO());
        return "registration";
    }

    @PostMapping("/registration")
    public String registration(@ModelAttribute("newUser") @Valid UserRegistrationDTO userRegistrationDTO,
                               BindingResult bindingResult, Model model) {
        if (bindingResult.hasErrors()) {
            return "registration";
        } else {
            boolean isRegistered = userService.save(userRegistrationDTO);
            if (isRegistered) {
                return "redirect:/user/authorization";
            } else {
                model.addAttribute("message", "User with this username is already exist");
                return "registration";
            }
        }
    }

Добрый день.
В чем именно проблема заключается-то? И если уж решили выложить весь код, то как вариант могу рекомендовать залить проект в гит

Орхан Гасанлы, проблема была в том что телефон не сохранялся.
Решил следующим изменением:

<div class="mb-3">
        <label for="Telephones" class="form-label">Telephone</label>
        <input type="text" class="form-control"  th:field="*{telephones[0].number}" id="Telephones">
        <p th:if="${#fields.hasErrors('telephones')}" th:errors="*{telephones[0].number}"></p>
    </div>
