uploadify批量上传图片

该上传摘自b-jui官网！ 具体效果可以查看：http://demo.b-jui.com/
该方法能一次选择多张图片，并能预览图片，取消上传，可以单独一张张上传，也可一次全部上传完成！
这里是一次全部上传，要单张上传得自己改代码！
引入的js，css改天加上下载路径，或去b-jui官网下载

   （1）controller

 @RequestMapping("/publicsaveFile")
     public @ResponseBody Map uploadPic(HttpServletRequest request,@RequestParam Map<String,String> map) throws Exception{
     try {
        mes=agentInfoService.uploadPic(request,map);
     } catch (Exception e) {
        logUtil.error("上传资料图片-------------异常："+e);
     }
     return mes;
