Spring MVCアプリケーションがあり、 Validatorを実装するValidationクラスがあります。この検証クラスは、@InitBinderアノテーションを使用してコントローラーで呼び出されます。この検証は、データベースにレコードを挿入する前に行われますが、更新を実行する場合、この検証クラスからすべてのフィールドを検証する必要はありません。同じビューを使用してレコードを挿入して更新すると、ビューにはHttpRequestに基づいて挿入と更新を処理するコントローラーがあります。
Validationクラスに、ユーザーが行うリクエストを指定して、更新後にuserNameを再度検証しないようにする方法はありますか？
このクラスにHttpリクエストを渡して、クラスでユーザー定義の操作を受け取り、それを使用して操作に基づいて検証を微調整する必要があるということですか？そうであれば、どのように行うことができますか？ユーザーの要求に基づいて検証クラスの特定のフィールドを検証し、データベースまたは更新に挿入したいと思います。
検証クラス
public class OfficerRegistrationValidation implements Validator{
private final Logger logger = Logger.getLogger(getClass());
@Autowired
public ValidateUserManager validateUserManager;
public boolean supports(Class<?> clazz) {
return Officers.class.equals(clazz);
}
public void validate(Object target, Errors errors) {
Officers officer = (Officers) target;
if (officer.getUserName() == null){.......................
リクエストを処理するコントローラ機能
@RequestMapping(value="officer_registration.htm", method=RequestMethod.POST)
public ModelAndView handleRequest(@Valid @ModelAttribute Officers officer,
BindingResult result,
ModelMap m,
Model model,
HttpServletRequest request,
HttpServletResponse response)throws Exception{
try{
if(result.hasErrors()){
model.addAttribute("division", myDivision);
model.addAttribute("position", myPosition);
model.addAttribute("gender", myGender);
return new ModelAndView("officer_registration");
}else{
//check the request if its an update or an insert
String user_request = request.getParameter("user_request");
logger.info("The Users Request Was " + user_request);
if (user_request.equals("Save")){
officerManager.RegisterOfficer(officer);
model.addAttribute("badgeNoStatus","true");
model.addAttribute("saveBtnStatus","disabled");
model.addAttribute("userNameStatus","true");
model.addAttribute("startDateStatus","true");
model.addAttribute("icon","ui-icon ui-icon-circle-check");
model.addAttribute("results","Record Was Saved");
}else{//if its an update
//only need certain validation from the validation class here
officerManager.UpdateOfficer(officer);

クラスに@Componentアノテーションを付け、@ AutowiredプライベートHttpServletRequestリクエストをこのためのゲッターとセッターと一緒に追加すると、次のエラーが発生します。
