 * @describe  静态化管理类
 * 	静态web页面时,需要 ServletContext的支持,那么从哪里可以获取这个 ServletContext呢.<br />
 * 在action中我们可以轻松获取 他，然后用他作为我们 的参数传进来。<br />
 * 可是  没有在action中获取呢，比如 在filter中，莫非也要让filter 集成 HttpServlet》？？<br />
 * 这个先不说行不行，光是这样想就觉得很别扭了<br />
 * 最后，选用的方案是， 在pojo中实现 Spring 的ServletContextAware 接口，然后由spring给我们自己加上ServletCOntext <br />
 * 要实现这个目的，我们的pojo必须是 Spring 里面的一个 bean，不然你的数据从哪里来？ <br />
