异常处理器@ExceptionHandler(RuntimeException.class)没生效，密码错误时直接报错了，没有返回500的页面

楼上的老哥，有没有在signin失败的时候抛出runtime exception？

顺着廖老师的教程做过来的话之前是return new ModelAndView的 得注掉那句然后把e给丢出去才行

    @PostMapping("/signin")   public ModelAndView doSignin(@RequestParam("email") String email, @RequestParam("password") String password,         HttpSession session) {      try {         User user = userService.signin(email, password);         session.setAttribute(KEY_USER, user);      } catch (RuntimeException e) {//       return new ModelAndView("signin.html", Map.of("email", email, "error", "Signin failed"));         throw e;      }      return new ModelAndView("redirect:/profile");   }
