   你好  请问 为什么


@RequestMapping(value = "/login", method = RequestMethod.POST)
28
+  public String fail(@RequestParam(FormAuthenticationFilter.DEFAULT_USERNAME_PARAM) String userName, Model model) {
29
+    model.addAttribute(FormAuthenticationFilter.DEFAULT_USERNAME_PARAM, userName);
30
+    return FormAuthenticationFilter.DEFAULT_ERROR_KEY_ATTRIBUTE_NAME != null ? "signUp" : "login";
31
+  }


这几行代码就能实现登录
能麻烦您详细解释一下吗? 谢谢
