Uploadify在Struts2中的施用(转)

Uploadify在Struts2中的应用(转)
步骤一： 到官网上下载uploadify的JS文件.
Uploadify在线演示：在线Demo
Uploadify配置参数及接口文档：http://www.uploadify.com/documentation
Uploadify插件下载地址：http://www.uploadify.com/download
--------------------------------
步骤二：下载好uploadify压缩包文件后，解压文件包。在文件夹中找到以下五个文件，并添加到项目的对应路径中：
    jquery.uploadify.v2.1.0.js
   swfobject.js
   uploadify.swf
   uploadify.css
   cancel.png
步骤三：加入struts2的jar包、struts.xml ，在web.xml中加入struts2的FilterDispatcher过滤器。

1、jsp代码：

----------------------------------------------------------
2、web.xml

----------------------------------------------------------
4、action代码
package com.lijigou.action;import java.io.File;import java.text.SimpleDateFormat;import java.util.Date;import javax.servlet.http.HttpServletResponse;import org.apache.struts2.ServletActionContext;import com.opensymphony.xwork2.ActionSupport;@SuppressWarnings("serial")public class UploadAction extends ActionSupport { private File uploadify;  private String uploadifyFileName;    @SuppressWarnings("deprecation") public String uploadFile() throws Exception {      String extName = "";//扩展名    String newFileName= "";//新文件名    String nowTime = new SimpleDateFormat("yyyymmddHHmmss").format(new Date());//当前时间    String savePath = ServletActionContext.getRequest().getRealPath("");    savePath = savePath +"/uploads/";  HttpServletResponse response = ServletActionContext.getResponse();  response.setCharacterEncoding("utf-8");    //获取扩展名  if(uploadifyFileName.lastIndexOf(".")>=0){   extName = uploadifyFileName.substring(uploadifyFileName.lastIndexOf("."));  }  newFileName = nowTime+extName;    uploadify.renameTo(new File(savePath+newFileName));    response.getWriter().print(uploadifyFileName+"上传成功");         return null; //这里不需要页面转向，所以返回空就可以了 } public File getUploadify() {  return uploadify; } public void setUploadify(File uploadify) {  this.uploadify = uploadify; } public String getUploadifyFileName() {  return uploadifyFileName; } public void setUploadifyFileName(String uploadifyFileName) {  this.uploadifyFileName = uploadifyFileName; }}

以上代码都通过测试，没有问题的。
