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));

        		}
            }
        }
