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+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>Uploadify</title>
<style type="text/css">
#div1{
color: #000000; font-size: 12px;
border: 0px solid #74B3DC;
color: #000;
background: #fff;
display:none;
}
</style>
<script type="text/javascript" src="/UploadFiles/2021-04-02/jquery-1.3.2.min.js">
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;

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*********************************
<"1.0" encoding="UTF-8" "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.i18n.encoding" value="UTF-8"/>
//设置上传文件最大量
<constant name="struts.multipart.maxSize" value="10485760"/>
<package name="upload" namespace="/" extends="struts-default" >
<action name="uploadAction" class="action.Upload" method="uploadAction">
<result name="success">/index.jsp</result>
</action>
</package>
</struts>
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。
