springboot中，增加過濾器后，頁面重定向跳轉與請求轉發跳轉，都出現報錯。

求大佬幫忙解答，謝謝！

一.頁面跳轉代碼：

1.重定向代碼：

response.sendRedirect("/test/error1");

2.請求轉發代碼：request.getRequestDispatcher("/test/error1").forward(request, response);

二.控制器代碼：

@RequestMapping("/test/error1")

//控制視圖

public String error1(ModelMap model) {

model.addAttribute(“s”,lists);

return “/test/error1”;

}

注:直接訪問控制視圖：http://localhost:8080/test/error1，可以正常打開。

三.錯誤異常：

1.頁面跳轉-錯誤頁面：

2.頁面跳轉報錯信息，如下：
