springmvc/uploadify 多文件上传

前台：

导入一下文件

swfobject.js

jquery-1.7.2.min.js

jquery.uploadify.v2.1.4.min.js

uploadify.css

给你一个容器按钮

<div><input type="file" name="uploadify" id="uploadify" value="00" class="uploadify-button"/></div>

$(document).ready(function () {
$("#uploadify").uploadify({
'uploader' : 'uploadify.swf',
'script' : '${pageContext.request.contextPath}/enclosure/upload',
'cancelImg' : 'img/cancel.png',
'folder' : 'upload',
'queueID' : 'fileQueue',
'auto' : false,
'multi' : true,
'simUploadLimit' : 2,
'buttonImg':'img/scfj.png',
'scriptData':{'applyMainId':$("#applyMainId").val()},
'onComplete' : function(event, ID,fileObj, response, data) {
location.href='${pageContext.request.contextPath}/enclosure/list?applyMainId='+${applyMainId};
}
});
})

<div id="fileQueue"></div>

cancel.png为自己本地删除图片，官方下载可以获得

后台：

@RequestMapping(value="/upload",method=RequestMethod.POST)  
@ResponseBody
    public String uploadify(@RequestParam("Filedata")MultipartFile multiFile,HttpServletRequest request, HttpServletResponse response,Integer applyMainId) throwsIOException, FileUploadException{
        System.out.println("name:"+multiFile.getOriginalFilename());
        System.out.println("inputstream"+multiFile.getInputStream());
        
        ServletContext sc = request.getSession().getServletContext();
        String dir = sc.getRealPath("/upload");//附件存放服务器的路径
        System.out.println(dir);
        File file = new File(dir);
        if(!file.exists()){
            file.mkdirs();
        }
        String filename = multiFile.getOriginalFilename();
        //防止文件被覆盖，以纳秒生成文件
        Long _l = System.nanoTime();
        String _extfilename = filename.substring(filename.lastIndexOf("."));
        filename = _l+_extfilename;
        String uploadPath = request.getContextPath()+""+dir+"/"+filename;
        String responseStr = "";
        
        try {
            FileUtils.writeByteArrayToFile(new File(dir, filename), multiFile.getBytes());
            responseStr = "上传成功！";
