任意のアドバイスのおかげでは...ここから

Answer 1

がエラー来ている...

@RequestMapping(value = { "/addApp" }, method = RequestMethod.POST) 
     public String saveApp(@Valid PIL_P_APPLCTN application, BindingResult result, ModelMap model) { 

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

      if (!appService.isObjectFieldUnique(application.getId(), application.getAPPLCTN_CD())) { 
       FieldError app_cdError = new FieldError("application", "APPLCTN_CD", messageSource.getMessage("non.unique.APPLCTN_CD", 
         new String[] { application.getAPPLCTN_CD() }, Locale.getDefault())); 
       result.addError(app_cdError); 
       return "formApp"; 
      } 

このようにあなたのコードがあることshuold：

@RequestMapping(value = { "/addApp" }, method = RequestMethod.POST) 
     public String saveApp(@Valid @ModelAttribute("application") PIL_P_APPLCTN application, BindingResult result, ModelMap model) { 
      model.addAttribute("application", application); 

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

      if (!appService.isObjectFieldUnique(application.getId(), application.getAPPLCTN_CD())) { 
       FieldError app_cdError = new FieldError("application", "APPLCTN_CD", messageSource.getMessage("non.unique.APPLCTN_CD", 
         new String[] { application.getAPPLCTN_CD() }, Locale.getDefault())); 
       result.addError(app_cdError); 
       return "formApp"; 
      } 

formApp.jsp

<form:form method="POST" commandeName="application" class="form-horizontal form-label-left" >
