java zyUpload 实现多文件上传

1、html部分

<form enctype="multipart/form-data">
　　<label>请选择文件</label> <input id="file" class="file" type="file">
</form>

2、js部分

$("#file").fileinput({
uploadUrl: Config.Java_Manage_Path+'black/uploadBlack',
allowedFileExtensions: ['xls', 'xlsx'],
dropZoneEnabled: false,
browseLabel:"选择",
showRemove: false,
showUpload: false,
uploadLabel: "提交",
showCancel: false,
maxFileSize: 6000,
msgSizeTooLarge: '"{name}" ({size} KB) 不得超过 {maxSize} KB. 请重新选择文件',
fileActionSettings: {
showZoom: false,//不显示预览按钮
uploadTitle: "上传",
removeTitle: "删除"
},
progressUploadThreshold: "导入中,请稍后...",
msgInvalidFileExtension: '仅支持 "{extensions}" 类型的文件.'
});
//点击上传后隐藏关闭按钮
  $('#file').on('filepreupload', function(event, data, previewId, index) {
//      var form = data.form, files = data.files, extra = data.extra,
//          response = data.response, reader = data.reader;
//      console.log('File pre upload triggered');
  $("#close").hide();
  });
  //上传完毕显示关闭按钮
  $('#file').on('fileuploaded', function(event, data, previewId, index) {
      /*var form = data.form, files = data.files, extra = data.extra,
          response = data.response, reader = data.reader;
      console.log('File uploaded triggered');*/
  var response = data.response;
  if(response.result == "ok"){
  $.messager.popup("导入成功");
  }else{
  $.messager.popup("服务器可能出错了，请稍候再试");
  }
  $("#close").show();
  $("#upload").modal("hide");
  doSearch();
  });

3、controller部分

 //创建一个通用的多部分解析器
        CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(req.getSession().getServletContext());
        //判断 request 是否有文件上传,即多部分请求
        if(multipartResolver.isMultipart(req)){
        //转换成多部分request
            MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) req;
         // 取得request中的所有文件名
            Iterator<String> iter = multiRequest.getFileNames();
            if(iter.hasNext()) {
             // 取得上传文件
                MultipartFile file = multiRequest.getFile(iter.next());
            String fileName = file.getOriginalFilename();        if (!fileName.endsWith(".xls") && !fileName.endsWith(".xlsx")) {
        this.response(req, res, false);
        }
        String newName = DateUtil.dateToStringT(new Date()) + fileName;
        File targetFile = new File(upload_path, newName);
        // 保存
//        try {
//        file.transferTo(targetFile);
//        } catch (Exception e) {
//        e.printStackTrace();
//        this.response(req, res, false,ResultCode.getMessage(ResultCode.EXCEPTION));
//        }
        FileOutputStream os = null;
        InputStream in = null;
        // 保存
        try {
        os = new FileOutputStream(upload_path+"/"+newName);
         //拿到上传文件的输入流
                    in = file.getInputStream();
                    //以写字节的方式写文件
                    int b = 0;
                    while((b=in.read()) != -1){
                        os.write(b);
                    }          } catch (Exception e) {
        e.printStackTrace();
        this.response(req, res,false,
        ResultCode.getMessage(ResultCode.EXCEPTION));
        }finally{
         os.flush();
                     os.close();
                     in.close();
        }
        // 读取excel
        ExcelImportUtil excelUtil = new ExcelImportUtil();
        excelUtil.setExcelPath(targetFile.getPath());
        excelUtil.setStartReadPos(1);
        List<Row> rowList = excelUtil.readExcel();        if (!(rowList != null && rowList.size() > 0)) {
        this.response(req, res, false,
        ResultCode.getMessage(ResultCode.FILE_READ_ERROR));
        }        
　　　　　　　　　　　　　　//读取文件内容添加到数据库
        Map<String, Object> map = blacklistservice.addBlackList( excelUtil, rowList);
        if (map != null) {
        this.response(req, res, JsonUtil.toJson(map));
        } else {
        this.response(req, res, false,
        ResultCode.getMessage(ResultCode.EXCEPTION));        }
            }
        }}
