Spring MVC驗證在新表單期間有效，但嘗試更新時無法顯示驗證

[英]Spring mvc validation working during new form but fail show validation when try to update

問題描述

我有一個輸入表單，用於添加和更新用戶信息。 相同的提交表單可以正確執行添加和更新操作，如果我嘗試故意提交空數據/錯誤格式，則會出現問題，在嘗試添加新用戶時，驗證可以顯示消息，但不能在更新用戶上顯示。 驗證包括NotEmpty / Email / typeMismatch等...

任何允許以相同形式顯示驗證消息的幫助嗎？ 為什么嘗試添加可以顯示而不在更新期間顯示？ 我剛剛啟動SpringMVC，希望有人幫忙。

提前致謝。

這是代碼： 

@ModelAttribute
public void getUserDetail(@RequestParam(value = "udId", required = false)  
    Integer udId,
    Map<String, Object> map) {

    //For update UserDetail form

    if (udId != null) {
        UserDetail userDetail = new UserDetail();
        try {
            userDetail = userDetailService.getUserDetail(udId);
        } catch (Exception e) {
            log.error("failed to get UserDetail with udId: " + udId);
        }
        map.put("userDetail", userDetail);
    }
}


//Add
@RequestMapping(value = "/userDetail", method = RequestMethod.POST)
public String saveUserDetail(@Valid UserDetail userDetail,
    BindingResult bingdingResult) {

    if (bingdingResult.getErrorCount() > 0) {
        log.info("User attempt create user: " + userDetail.toString());
        for (FieldError error : bingdingResult.getFieldErrors()) {
            log.info(error.getField() + ": " + error.getDefaultMessage());
        }
        //redirect to same page to show error return infor (NotEmpty etc...)
        return "/user/inputUserDetail";
    } else {
        try {
            userDetailService.addUserDetail(userDetail);
        } catch (Exception e) {
            log.error("Failed to add new UserDetail: " + 
                     userDetail.toString());
        }
        return "redirect:/user/userDetails";
    }
}

@RequestMapping(value = "/userDetail", method = RequestMethod.PUT)
public String updateUserDetail(@Valid UserDetail userDetail,
    BindingResult bingdingResult, Map<String, Object> map) {

    //Update - need UserDetail model attribute

    if (bingdingResult.getErrorCount() > 0) {
        log.info("User attempt update user: " + userDetail.toString());
        for (FieldError error : bingdingResult.getFieldErrors()) {
            log.info(error.getField() + ": " + error.getDefaultMessage());
        }
        // redirect to same page to show error return infor (NotEmpty etc...)
        // error cannot display error message
        return "/user/inputUserDetail";
    } else {
        try {
            //update user detail
            userDetailService.updateUserDetail(userDetail);
        } catch (Exception e) {
            log.error("Failed to update UserDetail: " +     
                   userDetail.toString());
        }
        return "redirect:/user/userDetails";
    }
}

附加編碼： 

//Service layer:
@Service("userDetailHistoryService")
@Transactional(propagation = Propagation.SUPPORTS, readOnly = true)
public class UserDetailHistoryServiceImpl implements UserDetailHistoryService{
    @Override
    public void updateUserDetailHistory(UserDetailHistory userDetailHistory) {
        userDetailHistoryDao.updateUserDetailHistory(userDetailHistory);
    }
    //other coding etc.. etc...
}

@Repository("userDetail")
public class UserDetailDaoImpl implements UserDetailDao {
    @Autowired
    private SessionFactory sessionFactory;

    //Dao layer:
    @Override
    public void updateUserDetail(UserDetail userDetail) {
        sessionFactory.getCurrentSession().update(userDetail);
    }
    //other coding etc.. etc...
}

歡迎任何建議和想法？ 再次感謝。

當我嘗試將更新提交到NotEmpty字段時發生錯誤，在下面附加長錯誤消息：

嘗試這樣： 

@RequestMapping(value = { "/new" }, method = RequestMethod.GET)
    public String newEmployee(ModelMap model) {
        Employee employee = new Employee();
        model.addAttribute("employee", employee);
        model.addAttribute("edit", false);
        return "registration";
    }

    @RequestMapping(value = { "/new" }, method = RequestMethod.POST)
    public String saveEmployee(@Valid Employee employee, BindingResult result,
            ModelMap model) {

        if (result.hasErrors()) {
            return "registration";
        }                   
        service.saveEmployee(employee);    
        return "success";
    }

@RequestMapping(value = { "/edit-{ssn}-employee" }, method = RequestMethod.GET)
    public String editEmployee(@PathVariable String ssn, ModelMap model) {
        Employee employee = service.findEmployeeBySsn(ssn);
        model.addAttribute("employee", employee);
        model.addAttribute("edit", true);
        return "registration";
    }


    @RequestMapping(value = { "/edit-{ssn}-employee" }, method = RequestMethod.POST)
    public String updateEmployee(@Valid Employee employee, BindingResult result,
            ModelMap model, @PathVariable String ssn) {

        if (result.hasErrors()) {
            return "registration";
        }    

        service.updateEmployee(employee);     
        return "success";
    }
