RediectAttributes不能与spring

Question

我在应用程序中使用spring security。

@RequestMapping("/method1")
public String firstMethod(Model model,RedirectAttributes redirectAttributes) {
  ... do something ...
  redirectAttributes.addFlashAttributes("message","This is a test message");
  return "redirect:/method2";
}

@RequestMapping("/method2")
public String secondMethod(@ModelAttribute("message") String message, Model model) {
  ... do something ...

  return "some_view";
}

Answer 1

使用AddAttribute而不是AddFlashAttributes

在这里阅读不同之处

@RequestMapping("/method1")
public String firstMethod(Model model,RedirectAttributes redirectAttributes) {
  redirectAttributes.addAttribute("message","This is a test message");
  return "redirect:/method2";
}

@RequestMapping("/method2")
public String secondMethod(@ModelAttribute("message") String message, Model model) {
  return "some_view";
}
