我有一个输入表单写入add＆amp;更新用户信息的目的。
相同的提交表单可以执行添加＆amp;正确更新，只是问题加剧，如果我试图故意提交空数据/错误的格式，验证可以显示消息，同时尝试添加新用户，但不是更新用户。
验证包括NotEmpty / Email / typeMismatch等...
允许以相同形式显示验证消息的任何帮助？ 为什么尝试添加可以显示，但不能在更新期间添加？ 我刚刚开始使用SpringMVC，希望有人帮忙。
提前致谢。
以下是代码：
@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";
}
}
附加编码：
//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...
}
欢迎任何建议和想法？ 再次感谢。
当我尝试向NotEmpty字段提交更新时出现错误，在附加长错误消息：

等....................................与hibernate相关的长消息...
答案 0 :(得分：0)
试试这样：
@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";
}
