上传页面编写：index.jsp

<%@ 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>

<title>jquery upload</title>

$(function () {

$("#file_upload").uploadify({

//指定swf文件

'swf': 'uploadify/uploadify.swf',

//后台处理的页面

'uploader': 'upload/testQiNiu.do',

'progressData' : 'speed',

//按钮显示的文字

'buttonText': '上传文件',

//显示的高度和宽度，默认 height 30；width 120

//'height': 15,

//'width': 80,

//上传文件的类型默认为所有文件 'All Files' ; '*.*'

//在浏览窗口底部的文件类型下拉菜单中显示的文本

'fileTypeDesc': 'All Files',

//允许上传的文件后缀

//'fileTypeExts': '*.gif; *.jpg; *.png',

'cancel': 'uploadify/cancel.png',

//上传文件页面中，你想要用来作为文件队列的元素的id, 默认为false 自动生成, 不带#

'queueID': 'fileQueue',

//选择文件后自动上传

'auto': false,

//设置为true将允许多文件上传

'multi': true,

/* 'onUploadComplete' : function(file) {

alert('上传完成');

}, */

'onCancel' : function(file) {

alert('取消上传');

}

});

</script>

</head>

<body>

<p>

<a href="javascript:$('#uploadify').uploadify('cancel')">取消所有上传</a>

</p>

</body>

</html>

工具类编写：IPTimeStamp.java

利用客户端IP+时间+三位随机数字生成非重复文件名

package com.qiang;

//PTimeStamp.java

import java.net.InetAddress;

import java.net.UnknownHostException;

import java.text.SimpleDateFormat;

import java.util.Date;

import java.util.Random;

public class IPTimeStamp {

private String ip;

private Date date;

private SimpleDateFormat format;

public IPTimeStamp() {

try {

ip = InetAddress.getLocalHost().getHostAddress();

} catch (UnknownHostException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

public String getTimeStamp() {

format = new SimpleDateFormat("yyyyMMddHHmmssSSS");

return format.format(new Date());

}

public String addZero(String str, int len) {

StringBuffer sb = new StringBuffer();

sb.append(str);

while (sb.length() < len) {

sb.insert(0, "0");

}

return sb.toString();

}

public String getIPTimeStampRandom() {

StringBuffer sb = new StringBuffer();

String[] ips = this.ip.split("\\.");

for (int j = 0; j < ips.length; j++) {

// System.out.println(ips[j]);

sb.append(this.addZero(ips[j], 3));

}

sb.append(this.getTimeStamp());

Random rod = new Random();

for (int i = 0; i < 3; i++) {

sb.append(rod.nextInt(10));

}

return sb.toString();

}

文件上传控制器编写：UploadController.java

package com.qiang;

import java.io.File;

import java.io.IOException;

import java.util.Iterator;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.commons.fileupload.FileItem;

import org.apache.commons.fileupload.FileUploadException;

import org.apache.commons.fileupload.disk.DiskFileItemFactory;

import org.apache.commons.fileupload.servlet.ServletFileUpload;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import com.qiniu.http.Response;

import com.qiniu.storage.Configuration;

import com.qiniu.storage.UploadManager;

import com.qiniu.util.Auth;

@Controller

@RequestMapping("/upload")

public class UploadController {

//设置好账号的ACCESS_KEY和SECRET_KEY

String ACCESS_KEY = "Le8jyHg71J7UuV***KYUmF-UMbJOZgmLMO"; //这两个登录七牛账号里面可以找到

String SECRET_KEY = "VMO5cIW***ifokRkefGE_WWxKmC2n2d";

//要上传的空间

String bucketname = "usercenterfilesccw"; //对应要上传到七牛上你的那个路径（自己建文件夹注意设置公开）

//上传到七牛后保存的文件名

String key = "test.doc";

//密钥配置

Auth auth = Auth.create(ACCESS_KEY, SECRET_KEY);

//创建上传对象

Configuration conf=new Configuration();

UploadManager uploadManager;

{

uploadManager=new UploadManager(conf);

}

/**上传到本地服务器

* @param request

* @param response

@RequestMapping("/test.do")

public void test(HttpServletRequest request,HttpServletResponse response){

String savePath = request.getSession().getServletContext()

.getRealPath("");

// 得到项目的工作目录

savePath = savePath + "/uploads/";

File f1 = new File(savePath);

// 如果没有的话就创建目录

if (!f1.exists()) {

f1.mkdirs();

}

DiskFileItemFactory fac = new DiskFileItemFactory();

ServletFileUpload upload = new ServletFileUpload(fac);

upload.setHeaderEncoding("utf-8");

List<FileItem> fileList = null;

try {

fileList = upload.parseRequest(request);

} catch (FileUploadException ex) {

return;

}

Iterator<FileItem> it = fileList.iterator();

String name = "";

String extName = "";

while (it.hasNext()) {

FileItem item = it.next();

if (!item.isFormField()) {

// 解析文件

name = item.getName();

long size = item.getSize();

String type = item.getContentType();

if (name == null || name.trim().equals("")) {

continue;

}

// 得到文件的扩展名

if (name.lastIndexOf(".") >= 0) {

extName = name.substring(name.lastIndexOf("."));

}

File file = null;

do {

// 利用客户端IP+时间+三位随机数字生成非重复文件名：

name = new IPTimeStamp().getIPTimeStampRandom();

file = new File(savePath + name + extName);

} while (file.exists());

File saveFile = new File(savePath + name + extName);

try {

item.write(saveFile);

} catch (Exception e) {

e.printStackTrace();

}

try {

response.getWriter().print(name + extName);

} catch (IOException e) {

e.printStackTrace();

}

/**上传到七牛云端

* @param request

* @param response

@RequestMapping("testQiNiu.do")

public void testQN(HttpServletRequest request,HttpServletResponse response){

List<FileItem> fileList = null;

try {

DiskFileItemFactory fac = new DiskFileItemFactory();

ServletFileUpload upload = new ServletFileUpload(fac);

fileList = upload.parseRequest(request);

} catch (FileUploadException ex) {

return;

}

Iterator<FileItem> it = fileList.iterator();

try {

while (it.hasNext()) {

FileItem item = it.next();

Response res = uploadManager.put(item.getInputStream(), key, getUpToken(),null, "application/zip");

System.out.println(res.getInfo());

}

} catch (Exception e) {

e.printStackTrace();

}

//简单上传，使用默认策略，只需要设置上传的空间名就可以了

public String getUpToken(){

return auth.uploadToken(bucketname);

}
