spring mvc验证分组

@Table(name = "user1")
@Component
public class  {
    @Id
    @Column(name = "uid1")
    @GeneratedValue
    private Integer uId;
    @NotEmpty(message = "请输入昵称", groups = {User.regist.class})
    private String uName;
    @NotEmpty(message = "邮箱不能为空", groups = {User.login.class,User.regist.class})
    @Email(message = "邮箱格式不正确", groups = {User.login.class,User.regist.class})
    private String uEmail;
    @NotEmpty(message = "密码不能为空", groups = {User.login.class,User.regist.class})
    @Length(min = 8, max = 16, message = "密码长度必须为8-16位", groups = {User.login.class,User.regist.class})
    private String uPassword;
    
    ...省略get set 等方法
     public interface login{};
     public interface regist{};

   @RequestMapping(value = "/logging", method = RequestMethod.POST)
   public String login(@ModelAttribute("user") @Validated(User.login.class) User user, BindingResult result, Errors errors, HttpSession session) {
      此处省略N行代码
      ...
   }
   //注册
   @RequestMapping(value = "/registing", method = RequestMethod.POST)
   public String regist(@ModelAttribute("user") @Validated(User.regist.class) User user, BindingResult result, @ModelAttribute("uQrpassword") String uQrpassword) {
      此处省略N行代码
