效果图：
第一张：这个是列出了全部的新闻标题，如果没有UrlRewrite的话，地址栏实际显示的应该是 http://localhost:8080/fkw/servlet/NewsServlet2?action=listNews 而经过UrlRewrite，目前如下显示 下面每一条新闻标题的超链接都是：http://localhost:8080/fkw/news/showNews_newid.html newsid为每一条新闻的id
第二张图： 这张是对某一条新闻的具体显示 实际访问的地址其实是： http://localhost:8080/fkw/servlet/NewsServlet2?action=getNews&newsid=3 现在如下显示
