我的例子：

1.jsp页面

1.1 index

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><%String path = request.getContextPath();String basePath = request.getScheme() + "://"+ request.getServerName() + ":" + request.getServerPort()+ path + "/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><base href="<%=basePath%>"><title>My JSP 'index.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0"><meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><title>Insert title here</title> <!--装载文件-->   <link rel="stylesheet" href="/js/uploadify/uploadify.css" type="text/css"></link> <script type="text/javascript" src="/js/jquery-1.4.2.min.js"></script><script type="text/javascript" src="/js/jquery.js"></script><script type="text/javascript" src="/js/uploadify/jquery.uploadify.min.js"></script><script type="text/javascript" src="/js/uploadify/jquery.uploadify.js"></script></head><body>This is my JSP page.<br><a href="upload.jsp">upload</a><a href="<%=path%>/test/hell.action">_hello_</a></body></html>

1.2 upload.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><title>Insert title here</title> <!--装载文件-->   <link rel="stylesheet" href="js/uploadify/uploadify.css" type="text/css"></link><script type="text/javascript" src="js/jquery.js"></script><script type="text/javascript" src="js/jquery-1.4.2.min.js"></script><script type="text/javascript" src="js/uploadify/jquery.uploadify.min.js"></script><script type="text/javascript" src="js/uploadify/jquery.uploadify.js"></script><%-- --%><script type="text/javascript" src="/js/uploadify/swfobject.js"></script>   <script type="text/javascript">$(function(){initUploadify();});    function initUploadify(){        $('#uploadify').uploadify({        'swf' : 'js/uploadify/uploadify.swf',//上传按钮的图片，默认是这个flash文件        "uploader":"test/test_upload.action",        'cancelImg' : 'js/uploadify/uploadify-cancel.png',//取消图片        'fileObjName':'uploadFiles',          'method':'post',        'queueID' : 'uploadifyQueue',//上传显示进度条的那个div        'buttonText' : '请选择文件',        'auto' : false,        'multi' : true,        'fileSizeLimit':'20MB'        });    }  </script></head><body>    <input id="uploadify" name="uploadFiles" value="上传"/>    <div id="uploadifyQueue"></div>     <p>     <!-- 加上“*”表示当第一个文件上传成功后，立即上传以后队列中的文件，否则需要自己手动 -->     <a href="javascript:$('#uploadify').uploadify('upload','*')">上传</a>     </p></body></html>

2. Action代码

package action;import java.io.File;import java.io.IOException;import java.util.List;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.commons.httpclient.HttpClient;import org.apache.log4j.Logger;import org.apache.struts2.ServletActionContext;import com.opensymphony.xwork2.ActionSupport;public class ProduceAction extends ActionSupport {static Logger log = Logger.getLogger(HttpClient.class.getName());/** *  */private static final long serialVersionUID = 1L;@Overridepublic String execute() throws Exception {System.out.println("登录");System.out.println(super.execute());return super.execute();}public String login() {System.out.println("登录:login");return "success";}/* * 下面的uploadFiles有两点需要注意 1、必须是List数组 * 2、命名必须跟jsp页面中的uploadify的一个参数"fileObjName"一致，否则无法获取到上传的文件 */public List<File> uploadFiles;/* * 下面的两个属性为使用Action上传文件所必须的，在前台jsp页面无需做任何操作 */public List<String> uploadFilesFileName;public List<String> uploadFilesContentType;public String upload() {HttpServletRequest request = ServletActionContext.getRequest();HttpServletResponse respon = ServletActionContext.getResponse();for (int i = 0; i < uploadFilesFileName.size(); i++) {System.out.println(uploadFilesFileName.get(i));}for (int i = 0; i < uploadFiles.size(); i++) {System.out.println(uploadFiles.get(i).getName());}try {respon.getOutputStream().print("成功");} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}return NONE;}public List<File> getUploadFiles() {return uploadFiles;}public void setUploadFiles(List<File> uploadFiles) {this.uploadFiles = uploadFiles;}public List<String> getUploadFilesFileName() {return uploadFilesFileName;}public void setUploadFilesFileName(List<String> uploadFilesFileName) {this.uploadFilesFileName = uploadFilesFileName;}public List<String> getUploadFilesContentType() {return uploadFilesContentType;}public void setUploadFilesContentType(List<String> uploadFilesContentType) {this.uploadFilesContentType = uploadFilesContentType;}}
