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();
		}
	}
}
