所有已实现的接口:
cn.taketoday.ui.Model, Serializable, Cloneable, Comparable<RedirectModel>, Map<String,Object>
public class RedirectModel extends cn.taketoday.ui.ModelMap implements Serializable, Comparable<RedirectModel>
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 cn.taketoday.web.view.RedirectView.

Example usage in an @Controller: 

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