    public static HttpServletRequest getRequest() {
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();

    public static HttpSession getSession() {
        HttpSession session = getRequest().getSession();
        return session;
    }

    public static HttpServletResponse getResponse() {
