 //获取请求头信息

 x-forwarded-for : <%=request.getHeader("x-forwarded-for")%> 

 RemoteAddr : <%=request.getRemoteAddr()%> 
文件会自动追加内容,操作完后下载:

%> --------------------编程问答-------------------- 好像最近越来越多的网友喜欢在 jsp 里完成所有业务逻辑了 --------------------编程问答-------------------- 这是一朋友要写的东西。
如果我还搞个环境比如，MVC,写数据库,mybaits...Ajax.....
我朋友那没有运行环境。
不过，现在框架用多了。真有点怀念JSP。 --------------------编程问答-------------------- 这是分享吗？ no perfect
