多个文件上传分为List集合和数组，下面我们着重介绍一下list集合的上传。都大同小异。
下面是extjs效果图
上传成功后的效果图
下面是extjs的实现代码
Ext.onReady(function() { //音乐上传信息 Ext.BLANK_IMAGE_URL = "/extjs/images/s.gif"; var music=[ { name : 'worksId', type : 'integer', sortable : true }, { name : "isbn", type : "string", sortable : true }, { name : "name", type : "string", sortable : true }, { name : "author", type : "string", sortable : true }, { name : "description", type : "string", sortable : true }, { name : "publish", type : "string", sortable : true },{ name : "price", type : "float", sortable : true }, { name : "number", type : "integer", sortable : true }, { name : "telecom", type : "string", sortable : true },{ name : "move", type : "string", sortable : true } ,{ name : "link", type : "string", sortable : true },{ name : "web", type : "string", sortable : true },{ name : "webname", type : "string", sortable : true },{ name : "exclusive", type : "string", sortable : true },{ name : "copyright", type : "string", sortable : true },{ name : "sublicense", type : "string", sortable : true },{ name : "pname", type : "string", sortable : true },{ name : "accredit", type : "string", sortable : true },{ name : "Btime", type : "string", sortable : true } ];

前台接收上传的数据是通过jsp接收session来获得的，下面是jsp接收session代码
<%@ page language="java" import="java.util.*" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%><%@page import="com.ising99.pojo.Book"%><%@page import="net.sf.json.JSONArray"%><% System.out.println("-------------------------"); List<Book> list=(List<Book>)session.getAttribute("list"); response.getWriter().write(JSONArray.fromObject(list).toString()); //int sizes=(Integer)session.getAttribute("size"); //response.getWriter().write("{\"list2\":"+JSONArray.fromObject(sizes).toString()+","); %>项目下载地址：
