spring6移除了对freemaker的jsp支持，所以导致了内置的Request对象用不了，可以在PermissionInterceptor下添加以下代码

@Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        if (modelAndView != null) {
            Map<String, Object> attributes = new HashMap<>();
            Enumeration<String> enumeration = request.getAttributeNames();
            while (enumeration.hasMoreElements()) {
                String key = enumeration.nextElement();
                attributes.put(key, request.getAttribute(key));
            }
            modelAndView.addObject("Request", attributes);
        }
    }
