Springmvc jsr303 validator coexists with spring WebDataBinder validator in one action

Since springmvc 3.x now supports jsr303 and the old spring style stylizer, I want to mix them in my application examples. But for the specified controller, only one method is included, is the spring frame restriction or JSR standard?

Here is my sample code.

User.java, stands for domain model, uses JSR303 for verification.

public class User{
    @Size(max = 16, message = "user loginId max-length is 16")
    private String loginId;
    //omit getter and setter
}

UserValidator.java implements an interface org.springframework.validation.Validatorto support user validation.

public class UserValidator implements Validator {

    private UserService userService;
    public boolean supports(Class<?> clazz) {
        return User.class.isAssignableFrom(clazz);
    }

    public void validate(Object target, Errors errors) {
            User u = (User) target;

            // loginName check for new user
            if (u.getUserId() == null && !userService.isLoginIdUnique(u.getLoginId(), null)) {
                    errors.rejectValue("loginId", "user.loginId.unique", new Object[] { u.getLoginId() }, null);
            }
    }

    @Autowired
    public void setUserService(UserService userService) {
            this.userService = userService;
    }

}

UserController.java uses annotation InitBinderto insert UserValidatorinto WebDataBinder.

@Controller("jspUserController")
@RequestMapping("/sys/users")
public class UserController {
    private UserValidator userValidator;

    @Autowired
    public void setUserValidator(UserValidator userValidator) {
        this.userValidator = userValidator;
    }

/*@InitBinder("user")
    public void initBinderUser(WebDataBinder binder) {
        binder.setValidator(userValidator);
    }*/

    @RequestMapping(value = "/save")
    public String save(@Valid User user, BindingResult bindingResult, Model model, HttpServletRequest request) {
        if (bindingResult.hasErrors()) {
            return "/sys/user/edit";
        }
        userService.saveUser(user);
        return "redirect:/sys/users/index";
    }
}

@InitBinder("user") UserController, JSR303 . JSR . - , ?

LocalValidatorFactoryBean (JSR-303) :

    @Controller("jspUserController")
    @RequestMapping("/sys/users")
    public class UserController {
        private UserValidator userValidator;

        @Autowired
        public void setUserValidator(UserValidator userValidator) {
            this.userValidator = userValidator;
        }

        @RequestMapping(value = "/save")
        public String save(@Valid User user, BindingResult bindingResult, Model model, HttpServletRequest request) {
            this.userValidator.validate(user, bindingResult);
            if (bindingResult.hasErrors()) {
                return "/sys/user/edit";
            }
            userService.saveUser(user);
            return "redirect:/sys/users/index";
        }
    }

:

@InitBinder("user")
public void initBinderUser(WebDataBinder binder) {
    binder.addValidators(userValidator);
}

JSR303, . .
