4. 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 >

     < base  href = " <%= basePath %> " >

     < title > jquery upload title >

     < link  rel = "stylesheet"  href = "uploadify/uploadify.css"  type = "text/css" > link >  

     < script  type = "text/javascript"  src = "js/jquery-1.4.2.min.js" > script >

     < script  type = "text/javascript"  src = "uploadify/jquery.uploadify.min.js" > script >

     < script  type = "text/javascript" >

        $( 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 >

     < div  id = "fileQueue" > div >  

     < input  type = "file"  name = "file_upload"  id = "file_upload"  />

     < p >  

         < a  href = "javascript:$('#file_upload').uploadify('upload','*')" > 开始上传 a >   

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

     p >

5. 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();

     }

}

6. 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

      */

      @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()) {

           DiskFileItemFactory fac =  new  DiskFileItemFactory();

           ServletFileUpload upload =  new  ServletFileUpload(fac);

           List fileList =  null ;

            try  {

           }  catch  (FileUploadException ex) {

                 return ;

           }

           Iterator 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 fileList =  null ;

            try  {

                DiskFileItemFactory fac =  new  DiskFileItemFactory();

                     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 );

       }

}
