springMVC+uploadify3.1 文件上传 demo

uploadify3.1 api 可参考：（点击打开链接）

需要springmvc的jar包

1、upload.jsp(主要代码)

 

<script type="text/javascript" charset="UTF-8"
    src="${pageContext.request.contextPath}/js/jquery1.11.js"></script>
<script type="text/javascript" charset="UTF-8"
    src="${pageContext.request.contextPath}/static/llsfw/js/upload/upload.js"></script>
    <script type="text/javascript" charset="UTF-8"
    src="${pageContext.request.contextPath}/static/llsfw/common/uploadify/jquery.uploadify.min.js"></script>


<div id="uploader">
        <p>
            <input type="file" name="file_upload" id="file_upload" />
        </p>
        <a href="javascript:$('#file_upload').uploadify('upload','*')">上传</a>
        <a href="javascript:$('#file_upload').uploadify('stop')">取消上传</a>
        <div id="uploader_queue"></div>
        <div id="uploader_msg"></div>
        <div id="uploader_view"></div>
    </div>

2、upload.js

 

 

$(function() {
     $("#file_upload").uploadify({
           'auto' : false,
           'method' : "get",
           'formData' : {'folder' : 'file'},
              'height' : 30,
              'swf' : basePath+'static/llsfw/common/uploadify/uploadify.swf', // flash
              'uploader' : basePath+'uploadController/upload', // 数据处理url
              'width' : 120,
              'fileTypeDesc' : '只能是xls...',
              'fileTypeExts' : '*.xls',
              'fileSizeLimit' : '10500KB',
              'buttonText' : '选择文件',
              'uploadLimit' : 5,
              'successTimeout' : 5,
              'requeueErrors' : false,
              'removeTimeout' : 10,
              'removeCompleted' : false,
              'queueSizeLimit' :10,
              'queueID'  : 'uploader_queue',
              'progressData' : 'speed',
              'onInit' : function (){},
           // 单个文件上传成功时的处理函数
           'onUploadSuccess' : function(file, data, response){
         $("#uploader_view").append('<div height="60" >'+data+'</div>');
        },
              'onQueueComplete' : function(queueData) {
         $('#uploader_msg').html(queueData.uploadsSuccessful + ' 个文件上传成功。');
        }
          });

});

 

3、UploadController.java

package com.llsfw.core.controller.upload;

import java.io.File;
import java.io.IOException;
import java.util.Iterator;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.MultipartHttpServletRequest;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;

import com.llsfw.core.controller.base.BaseController;

@Controller
@RequestMapping("uploadController")
public class UploadController extends BaseController {
    @RequestMapping("init")
    public String init() {
        return "llsfw/upload/upload";
    }

    @RequestMapping("upload")
    public void upload(HttpServletRequest request, HttpServletResponse response) {
        try {
            String savePath = "C://uploads/";
            File dirPath = new File(savePath);
            if (!dirPath.exists()) {
                dirPath.mkdirs();
            }
            // 解析器解析request的上下文
            CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(
                    request.getSession().getServletContext());
            // 先判断request中是否包涵multipart类型的数据，
            if (multipartResolver.isMultipart(request)) {
                // 再将request中的数据转化成multipart类型的数据
                MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;
                @SuppressWarnings("rawtypes")
                Iterator iter = multiRequest.getFileNames();

                while (iter.hasNext()) {
                    MultipartFile file = multiRequest.getFile((String) iter.next());
                    if (file != null) {
                        String fileName = file.getOriginalFilename();
                        System.out.println(fileName);
                        File localFile = new File(savePath + fileName);
                        // 写文件到本地
                        file.transferTo(localFile);
                        response.getWriter().print(fileName+"        上传成功！");
                    }
                }
            }

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
