spring-session sessionDestroyed

    public void sessionDestroyed(HttpSessionEvent httpSessionEvent) {
        logger.trace("会话销毁");

        // 功能实现：将session过期的用户的状态设置为离线
        HttpSession session = httpSessionEvent.getSession();
        String sessionId = session.getId();

        // 注意：不要用sessionOld，必须用session。
        // 1.sessionOld的与session,运行时的实例是不同的。
        // 2.sessionOld的与session,分别调用session.getAttribute("xxx")；前者会报错，后者则正常。
        // TODO renguoqiang 未注释如下代码行，是为了方便批量查找相关代码，排除相关隐患。
        HttpSession sessionOld = ContextHolderUtils.getSession(sessionId);

        ClientManager.getInstance().removeClinet(sessionId);
