Ich habe ein Projekt im Spring Web Modell-View-Controller (MVC) Framework. Die Version des Spring Web Model-View-Controller (MVC) -Frameworks ist 3.2.8.RedirectAttributes im Frühjahr MVC 3.2.8
Ich habe diese Methode
@RequestMapping(value = { "/newdesign/manage/device/award",
"/newdesign/manage/device/award/"}, method = {RequestMethod.POST})
public String awardDeviceProduct(
@ModelAttribute("deviceForm") DeviceForm deviceForm,
HttpServletRequest request,
Model model,
final RedirectAttributes redirectAttributes) throws Exception {
checkUser (request, UserRole.MARKETING);
Device device = manageLicenseService.getDeviceById(deviceForm.getDevice().getId());
if (deviceForm.getDevice().getIos()==null) {
model.addAttribute ("errorMessage", "Licence Number cannot be null !");
redirectAttributes.addFlashAttribute("errorMessage", "Licence Number cannot be null !");
} else if (deviceForm.getSelectedItems()!=null &&
!deviceForm.getSelectedItems().isEmpty()) {
// check LICENCE DUPLICATED
manageLicenseService.applyStatusChange (device, deviceForm.getSelectedItems(), Status.AWARDED);
} else {
model.addAttribute ("errorMessage", "no Items selected !");
model.addAttribute ("productGroup", getNotExpiredProductGroups (request));
}
return "redirect:/newdesign/manage/device/" + deviceForm.getDevice().getId();
}
Aber in der JSP kann ich nicht das Attribut "errormessage" finden !!!! when (deviceForm.getDevice(). getIos() == null)
