springMVC 中 webuploader同时上传多个文件

springMVC 中 webuploader同时上传多个文件

1 导入包 webuploader-0.1.5

2 配置

3 jsp中代码

<th width="20%">上传:</th>
     <td>
     
         <div id="upload">
             <div id="filePicker">文件上传</div>
         </div>
         <script type="text/javascript">
             var uploader = WebUploader.create(
                 {
                     swf:"${ctx}/static/webuploader-0.1.5/Uploader.swf",
                     server:"${ctx}/express/checkResult/uploadSeal",
                     pick:"#filePicker",
                     auto:true,
                     accept: {
                         title: 'Images',
                         extensions: 'gif,jpg,jpeg,bmp,png',
                         mimeTypes: 'image/*'
                     }
                 }      
             );
         </script>
         <textarea  id="uploadCover" name="uploadCover"  style="200px; display:none"  text=""></textarea>
 

3 写controller

public static String COM_REPORT_PATH = "D:";
  @RequestMapping("uploadSeal")
     public void upload(@RequestParam(value = "file", required = false) MultipartFile file,HttpServletResponse response, HttpServletRequest request, ModelMap model) { 
         System.out.println("upload image 开始"); 
         String path =COM_REPORT_PATH+"/upload/"; 
         String fileName = file.getOriginalFilename(); 
         System.out.println(path); 
         File baseFile = new File(path);
   File targetFile = new File(baseFile, fileName);   
   long size=0;
   if(!baseFile.exists()){ 
    baseFile.mkdirs(); 
         }       
         //保存 
         try { 
             file.transferTo(targetFile);
             size  = file.getSize();
         } catch (Exception e) { 
             e.printStackTrace(); 
         } 
         System.out.println(path+fileName);
         model.addAttribute("fileUrl", path+fileName);
  
      PrintWriter out;
   try {
    request.setCharacterEncoding("utf-8");
    response.setCharacterEncoding("utf-8");
    out = response.getWriter();  
//    out.println("文件上传成功. 已保存为: " + path + "." + fileName
//      + " &nbsp;&nbsp;文件大小: " + size + "字节<p />");
    out.println("<input type='hidden' name='imgaddress' value='"+ path + "." + fileName+"'>");
   } catch (IOException e) {
    e.printStackTrace();
   }   
     }
