jquery中的ajax异步上传
本篇文章给大家介绍jquery中的ajax异步上传，在此需要引入ajaxfileupload.js这个js文件。接下来，有需要的朋友跟着小编一起学习吧
找了好久终于在网上找到了ajax异步上传文件的方法，不过网上大多数是php的 ，我改为struts2写的 大同小异，希望对学习java的人有一定的帮助。我上传的是音乐文件。
ajaxfileupload.js这个js文件是主要文件，一定要导入。
jsp页面 ，其中我还做了div的隐藏*****************************
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+ ":"+request.getServerPort()+path+"/"; %>Uploadify
action上传后台代码*************************************
package action; import java.io.File; import java.io.IOException; import java.io.OutputStream; import org.apache.commons.io.FileUtils; import org.apache.struts2.json.annotations.JSON; import org.farng.mp3.MP3File; import org.farng.mp3.TagException; import org.farng.mp3.id3.AbstractID3v2; import org.farng.mp3.id3.ID3v1; import org.farng.mp3.lyrics3.AbstractLyrics3; import com.base.BaseAction; import com.opensymphony.xwork2.ActionSupport; public class Upload extends BaseAction { private static final long serialVersionUID = -4848248679889814408L; private String fileName; private File upload; public File getUpload() { return upload; } public void setUpload(File upload) { this.upload = upload; } public void setUploadFileName(String fileName) { this.fileName = fileName; } /* * 歌曲上传 上传操作 */ public void uploadAction() throws IOException { System.out.println("进入了该方法！"); String targetDirectory = "D:\\upload"; System.out.println(upload); File target = new File(targetDirectory, fileName); FileUtils.copyFile(upload, target); String path = targetDirectory+"\\"+fileName; try { MP3File file = new MP3File(path);//1,lyrics AbstractID3v2 id3v2 = file.getID3v2Tag(); ID3v1 id3v1 = file.getID3v1Tag(); String ss = ""; if (id3v2 != null) { System.out.println("id3v2"); ss = id3v2.getAlbumTitle()+";"+id3v2.getSongTitle()+";"+id3v2.getLeadArtist(); //String str = "{'msg','"+ss+"'}"; String str = ss; outPut(str); System.out.println(id3v2.getAlbumTitle());//专辑名 System.out.println(id3v2.getSongTitle());//歌曲名 System.out.println(id3v2.getLeadArtist());//歌手 } else { System.out.println("id3v1"); System.out.println(id3v1.getAlbumTitle()); System.out.println(id3v1.getSongTitle()); System.out.println(id3v1.getLeadArtist()); } AbstractLyrics3 lrc3Tag = file.getLyrics3Tag(); if (lrc3Tag != null) { String lyrics = lrc3Tag.getSongLyric(); System.out.println(lyrics); } } catch (IOException e) { e.printStackTrace(); } catch (TagException e) { e.printStackTrace(); } System.out.println("over"); } }struts.xml配置文件*********************************
//设置上传文件最大量 /index.jsp
后来经过调试，发现火狐和ie不兼容 导致无执行争取结果，所以我上传ajaxfileupload.js 我修改了源码
以上是本文给大家介绍jquery中的ajax异步上传，希望对大家有所帮助。
