uploadify是来自国外的一款优秀的jQuery上传插件，主要功能是批量上传文件，带进度显示。
下面以HTML5 Version版本为例介绍uploadifive的使用，结合Struts2
各软件版本如下：
jQuery ：1.8.0
Struts2 : 2.3.16.3
UploadiFive : 1.2.2
由于HTML5 Version是收费的，但可移步到download进行下载
一、添加对js和css文件的引用
<script type="text/javascript" src="uploadify/jquery-1.8.0.min.js"></script><script type="text/javascript" src="uploadify/jquery.uploadifive.min.js"></script><link rel="stylesheet" type="text/css" href="uploadify/uploadifive.css">二、JSP页面代码
<body><input id="file_upload" type="file" name="file" /><div id="tip-queue"></div></body><script type="text/javascript"> ???$(function(){ ???$(‘#file_upload‘).uploadifive({ ?????????//‘auto‘ : false, ??//取消自动上传 ??????????‘uploadScript‘ : ‘fileUploadAction.action‘, //处理上传文件Action路径 ??????????‘fileObjName‘ : ‘file‘, ???????//文件对象 ???????‘buttonText‘ ??: ‘选择文件‘, ??//按钮显示文字 ????????‘queueID‘ ?????: ‘tip-queue‘, //提示信息放置目标 ????????‘fileType‘ ????: ‘image/*‘, ??//允许上传文件类型 ????????‘onUploadComplete‘ : function(file, data) { //文件上传成功后执行 ????????console.info(‘The file ‘ + file.name + ‘ uploaded successfully.‘); ???????} ???}); ???})</script>三、struts.xml
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN""http://struts.apache.org/dtds/struts-2.0.dtd"><struts><package name="ajax_code" extends="json-default"> ?????????<!-- 文件上传 --> ?????????<action name="fileUploadAction" class="com.home.FileAction" method="fileUpload"> ?????????????<result type="json" name="success"> ?????????????????<param name="contentType">text/html</param> ?????????????</result> ?????????</action> ?????</package> ?</struts>四、处理上传文件Action
import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.InputStream;import org.apache.struts2.ServletActionContext;public class FileAction {private File file; // 文件private String fileFileName; // 文件名private String filePath; // 文件路径private InputStream inputStream;/** * 文件上传 * ?* @return */public String fileUpload() {String path = ServletActionContext.getServletContext().getRealPath("/upload");File ff = new File(path); // 判断文件夹是否存在,如果不存在则创建文件夹if (!ff.exists()) {ff.mkdir();}try {if (this.file != null) {File f = this.getFile();String fileName = java.util.UUID.randomUUID().toString(); // 采用时间+UUID的方式随即命名String name = fileName+ fileFileName.substring(fileFileName.lastIndexOf(".")); // 保存在硬盘中的文件名FileInputStream inputStream = new FileInputStream(f);FileOutputStream outputStream = new FileOutputStream(path+ "\\" + name);byte[] buf = new byte[1024];int length = 0;while ((length = inputStream.read(buf)) != -1) {outputStream.write(buf, 0, length);}inputStream.close();outputStream.flush();// 文件保存的完整路径// 比如：D:\tomcat6\webapps\eserver\\upload\a0be14a1-f99e-4239-b54c-b37c3083134a.pngfilePath = path + "\\" + name;}} catch (Exception e) {e.printStackTrace();}return "success";}public File getFile() {return file;}public void setFile(File file) {this.file = file;}public String getFileFileName() {return fileFileName;}public void setFileFileName(String fileFileName) {this.fileFileName = fileFileName;}public String getFilePath() {return filePath;}public void setFilePath(String filePath) {this.filePath = filePath;}public InputStream getInputStream() {return inputStream;}public void setInputStream(InputStream inputStream) {this.inputStream = inputStream;}}项目基本结构如下图：
效果如图：项目源码下载：download
