org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.web.servlet.mvc.support.RedirectAttributes]: Specified class is an interface
    at org.springframework.beans.BeanUtils.instantiateClass(BeanUtils.java:102)
    at org.springframework.web.servlet.mvc.multiaction.MultiActionController.newCommandObject(MultiActionController.java:521)

这是我的控制器代码

public String loginControl(HttpServletRequest request,HttpServletResponse response,RedirectAttributes redirectAttributes) throws NoSuchAlgorithmException{

      boolean status = false;
      String redirect = "home";
      String userName = request.getParameter("username");
      String password = request.getParameter("password"); 
      if(Utils.isNotNullNotEmptyNotWhiteSpaceOnly(userName) && Utils.isNotNullNotEmptyNotWhiteSpaceOnly(password)){
          User user = homeService.checkLogin(userName, password);
          if(user != null){
              HttpSession session = request.getSession(true);
              session.setAttribute("loggedUser", user);
              redirectAttributes.addFlashAttribute("status", "success");
              redirectAttributes.addFlashAttribute("messageHdr", "Password changed successfully");
              return "redirect:/home.mth";
          }
      }

在我的 application-servlet 中，我也包含在内<mvc:annotation-driven/>。

任何帮助表示赞赏。
