记录-Jquery uploadify文件上传实例

原本做的是from表单的文件上传,后来因需要用ajax异步,so接触到了Jquery uploadify上传

贴上代码,以供参考

 

 

需要引入的js文件

    <link href="../res/uploadify/uploadify.css" rel="stylesheet" type="text/css" />
    <script src="../res/uploadify/jquery.uploadify.min.js" type="text/javascript"></script>

下面是HTML代码

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

下面是Jquery代码

下面蓝色部分没用

$("#file").uploadify({
              height: 14,            
              swf: '/res/uploadify/uploadify.swf',
              uploader: '../member/getAllByExcel',
              width: 100,
              fileTypeExts: '*.xls',
              errorMsg: "不支持文件格式",
              buttonText:"Excel上传",
              multi :false, onUploadSuccess: function (file,data ,state) { var jsonData =$.parseJSON(data.replace(/\\/g,"\\\\")); if(data.msg){ alert(unescape(data.msg)); return; } $.appendMainPic(jsonData.images[0].url,jsonData.images[0].id); var orgValue = $("#Card_Pic_mainPic").val()+""; orgValue+=","+jsonData.images[0].id; $("#Card_Pic_mainPic").val(orgValue); }, onQueueComplete :function(a,b,c){}
       });

下面是后台代码

@RequestMapping(value="getAllByExcel" ,method = RequestMethod.POST)
    public Object getAllByExcel(HttpServletRequest request,HttpServletResponse response, ModelMap model){
        Map<String, Object> resMap=new HashMap<String, Object>();
        MultipartHttpServletRequest mulltipartRequest=(MultipartHttpServletRequest)request;
        
        Map<String, MultipartFile> fileMap = mulltipartRequest.getFileMap();
        for (Map.Entry<String, MultipartFile> entity : fileMap.entrySet()) {
            MultipartFile files = entity.getValue();
            //MultipartFile mf = entity.getValue();
            String path=request.getSession().getServletContext().getRealPath("/WEB-INF/res/upload");
            String fileName=files.getOriginalFilename();
            
            try {
                
              InputStream inputStream=files.getInputStream();
                
                byte[] b = new byte[1048576];
                int length = inputStream.read(b);
                path += "\\" + fileName;
                // 文件流写到服务器端
                FileOutputStream outputStream = new FileOutputStream(path);
                outputStream.write(b, 0, length);
                inputStream.close();
                outputStream.close();
              
                
                
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        
        //MultipartFile files=mulltipartRequest.getFile(null);
        //得到上传服务器路径
        resMap.put("msg", "录入成功");
        return resMap;
    }
