来源：互联网发布：手机棋牌游戏源码下载编辑：程序博客网时间：2024/05/22 02:28

前两天在看JavaEye时候看到了Uploadfy,因为之前没接触过,就研究了一下,从官方网址上下载了对应的包.

jquery.uploadify-v2.1.0.zip

Uploadify插件下载地址： http://www.uploadify.com/download

为了引起你的阅读兴趣,先看下运行的效果如图

下面我们就来对Struts2如何运用Uploadfy上传做些讲解.

首先去上面的网站下载jquery.uploadify-v2.1.0.zip 这个包

关于struts2的在这里就不用说了.

如何新建个1.jsp

代码如下:

<%@ page language="java" import="java.util.*" 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"><html> <head> <base href="<%=basePath%>"> <title>My JSP '1.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"><meta http-equiv="description" content="This is my page"> <link href="css/default.css" mce_href="css/default.css" rel="stylesheet" type="text/css" /><link href="css/uploadify.css" mce_href="css/uploadify.css" rel="stylesheet" type="text/css" /> <mce:script type="text/javascript" src="js/jquery-1.3.2.min.js" mce_src="js/jquery-1.3.2.min.js"></mce:script><mce:script type="text/javascript" src="js/swfobject.js" mce_src="js/swfobject.js"></mce:script><mce:script type="text/javascript" src="js/jquery.uploadify.v2.1.0.min.js" mce_src="js/jquery.uploadify.v2.1.0.min.js"></mce:script><mce:script type="text/javascript"></mce:script> </head> <body> <div id="fileQueue"></div> <input type="file" name="fileInput" id="fileInput" /> <a href="javascript:$('#fileInput').uploadifyUpload();" mce_href="javascript:$('#fileInput').uploadifyUpload();">上传文件</a><a href="javascript:$('#fileInput').uploadifyClearQueue();" mce_href="javascript:$('#fileInput').uploadifyClearQueue();">取消上传队列</a> <div id="result"></div> </body></html>

如何写个Action

package com.test.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;public class UploadifyAction extends ActionSupport { private File fileInput; private String fileInputFileName; @SuppressWarnings("deprecation") public String uploadFile() throws Exception { System.out.println("进入uploadFile"); 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(fileInputFileName.lastIndexOf(".")>=0){ extName = fileInputFileName.substring(fileInputFileName.lastIndexOf(".")); } newFileName = nowTime+extName; System.out.println(newFileName); fileInput.renameTo(new File(savePath+newFileName)); response.getWriter().print(fileInputFileName+"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 getFileInput() {return fileInput;}public void setFileInput(File fileInput) {this.fileInput = fileInput;}public String getFileInputFileName() {return fileInputFileName;}public void setFileInputFileName(String fileInputFileName) {this.fileInputFileName = fileInputFileName;}}

接着是在struts.xml里面对action进行配置

到此就结束了.

若需要程序的, 去这里下载

附加到myeclipse里面去后直接访问1.jsp.
