    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) {
