Spring Redirect

이제 redirect에도 @Pathvalueable이 적용 가능해졌다.

parameter로 덕지덕지붙은 redirect url을 더이상 안봐도 된다는것.

Interface RedirectAttributes

All Superinterfaces:

Model

All Known Implementing Classes:

RedirectAttributesModelMap

---

public interface RedirectAttributes
extends Model

A specialization of the Model interface that controllers can use to select attributes for a redirect scenario. Since the intent of adding redirect attributes is very explicit -- i.e. to be used for a redirect URL, attribute values may be formatted as Strings and stored that way to make them eligible to be appended to the query string or expanded as URI variables in org.springframework.web.servlet.view.RedirectView.

This interface also provides a way to add flash attributes. For a general overview of flash attributes see FlashMap. You can use RedirectAttributes to store flash attributes and they will be automatically propagated to the "output" FlashMap of the current request.

Example usage in an @Controller:

 @RequestMapping(value = "/accounts", method = RequestMethod.POST)
 public String handle(Account account, BindingResult result, RedirectAttributes redirectAttrs) {
   if (result.hasErrors()) {
     return "accounts/new";
   }
   // Save account ...
   redirectAttrs.addAttribute("id", account.getId()).addFlashAttribute("message", "Account created!");
   return "redirect:/accounts/{id}";
 }
 

A RedirectAttributes model is empty when the method is called and is never used unless the method returns a redirect view name or a RedirectView.

After the redirect, flash attributes are automatically added to the model of the controller that serves the target URL.
