webuploader 实现图片批量上传功能附实例代码

發布時間：2023/12/20 编程问答 31 豆豆

生活随笔收集整理的這篇文章主要介紹了 webuploader 实现图片批量上传功能附实例代码小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

1、導入資源

2、JSP代碼

<div class="page-container"><div class="row cl"><label class="form-label col-xs-4 col-sm-2"><spanclass="c-red">*</span>項目名稱：</label><div class="formControls col-xs-8 col-sm-9"><input type="text" class="input-text" value="${proName }"placeholder="" id="" name="proName" readonly="readonly"></div></div><div class="row cl"><label class="form-label col-xs-4 col-sm-2">縮略圖：</label><div class="formControls col-xs-8 col-sm-9"><div class="uploader-thum-container"><div id="fileList" class="uploader-list"></div><div id="filePicker">選擇圖片</div><button id="btn-star"class="btn btn-default btn-uploadstar radius ml-10">開始上傳</button></div></div></div><div class="row cl"><label class="form-label col-xs-4 col-sm-2"><spanclass="c-red">*</span>項目發票上傳：</label><div class="formControls col-xs-8 col-sm-9"><div class="uploader-list-container"><div class="queueList"><div id="dndArea" class="placeholder"><div id="filePicker-2"></div><p>或將照片拖到這里，單次最多可選300張</p></div></div><div class="statusBar" style="display:none;"><div class="progress"><span class="text">0%</span> <span class="percentage"></span></div><div class="info"></div><div class="btns"><div id="filePicker2"></div><div class="uploadBtn">開始上傳</div></div></div></div></div></div><div class="row cl"><div class="col-xs-8 col-sm-9 col-xs-offset-4 col-sm-offset-2"><buttononClick="article_add('','invoiceVo/save?&projectId=${projectId}&invoiceScan=','10001');"class="btn btn-primary radius" type="button"><i class="Hui-iconfont"></i> 保存 </button></div></div></div>

3、Js代碼

注意：

4、controller代碼

/*** 跳轉到上傳發票的頁面* @param proName* @param map* @return*/@RequestMapping(value = "/upload" )public String invoiceUpload(String proName,Long id,Map<String, Object> map){map.put("proName", proName);projectService.getProject(id);map.put("projectId", id);return "project/invoiceUpload";}/*** 上傳發票并保存導數據庫* @param file* @param request* @param response* @return*/@ResponseBody@RequestMapping(value = "/news_uploder", method ={RequestMethod.POST,RequestMethod.GET}, produces = "application/json; charset=utf-8") public JSONObject uploder(@RequestParam MultipartFile[] file,Long projectId,HttpServletRequest request,HttpServletResponse response){ String flag=null; JSONObject jsonObject = new JSONObject();try { WebuploaderUtil webuploaderUtil=new WebuploaderUtil(); webuploaderUtil.upload(file[0], "upload/invoice/", request); flag=webuploaderUtil.getFileName(); jsonObject.put("filePath", flag);jsonObject.put("status", "success");} catch (Exception e) { e.printStackTrace(); } return jsonObject; }5、工具類package com.softjx.util; /** *Project Name: QDLIMAP *File Name: WebuploaderUtil.java *Package Name: com.ltmap.platform.cms.util *Date: 2017年4月13日下午6:30:45 *Copyright (c) 2017,578888218@qq.com All Rights Reserved. */ import java.io.File;
