找了好久终于在网上找到了ajax异步上传文件的方法,不过网上大多数是php的 ,我改为struts2写的 大同小异,希望对学习java的人有一定的帮助。我上传的是音乐文件。ajaxfileupload.js这个js文件是主要文件,一定要导入。
jsp页面 ,其中我还做了div的隐藏*****************************
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+
":"+request.getServerPort()+path+"/";
%>

struts.xml配置文件*********************************

//设置上传文件最大量
/index.jsp
后来经过调试,发现火狐和ie不兼容 导致无执行争取结果,所以我上传ajaxfileupload.js 我修改了源码
