    public void contextInitialized(ServletContextEvent servletContextEvent) {

        ServletContext servletContext = servletContextEvent.getServletContext();

        ApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(servletContext);

        //将数据放到缓存中。

        servletContext.setAttribute("allNotLeafNodeList", "AAAAAAAAAAAAAAAAAAA");

        servletContextEvent.getServletContext().removeAttribute("allNotLeafNodeList");

    }

    public void contextDestroyed(ServletContextEvent servletContextEvent) {
