首先创建一个div
<div class="file-loading"> <input id="input-file-1" name="fileName" multiple type="file" accept="image/*" > </div>
javascript代码
<script> $("#input-file-1").fileinput({ language: "zh", uploadUrl: "/goods/add", autoOrientImage: true, multiple:true, maxFileCount:4, uploadAsync:false, uploadExtraData:{id:'kv-1',goodsName:"123"}, //额外添加的数据，后台有request.getPara取得 allowedFileExtensions: ["jpg", "jpeg", "gif", "png","bmp"],//单位为kb，如果为0表示不限制文件大小 layoutTemplates:{ // actionDelete: '',//设置为空字符串可以去掉对应的按钮 actionUpload:'', }, browseClass: 'btn btn-primary' }).on('fileuploaded', function(event, data) { //上传成功 alert("成功"); }) .on("fileuploaderror",function (event,data,msg) { //上传失败 alert("失败"); }) /* .on("filepreremove", function(jqXHR) { var abort = false; if (confirm("确定删除此图片?")) { abort = true; } return abort; // 您还可以发送任何数据/对象，你可以接收` filecustomerror });*/ </script> 后台代码
@ResponseBody @RequestMapping(value="/add",method = RequestMethod.POST) public String insertGoods(@RequestParam("fileName") MultipartFile imageFile[], //同步上床 获取多张图片参数 /*Goods goods,*/ HttpServletRequest request){ System.out.println("hello world"); Goods goods = new Goods(); if(imageFile!=null){ String imgUrl=""; for(int k=0;k<imageFile.length;k++) { imgUrl += saveImageFile(imageFile[k], request)+","; } goods.setImgUrl(imgUrl); } Date date=new Date(); goods.setUploadTime(date); GoodsEnum anEnum=goodsService.insertGoods(goods); if(anEnum.equals(GoodsEnum.INSERT_GOODS_SUCCESS)){ return JSONUtil.toJSON("success"); }else{ return JSONUtil.toJSON("error"); } } private String saveImageFile(MultipartFile imageFile, HttpServletRequest request) { //获取文件上传到服务器的路径 String uploadUrl=getRealPath(request)+"static/uploadImg/"; System.out.println("文件路径为："+uploadUrl); //获取从客户端传过来的文件名 String filename=imageFile.getOriginalFilename(); //判断文件上传的路径是否存在，若不存在，则需要创建它 File dir=new File(uploadUrl); if(!dir.exists()){ dir.mkdirs(); } //targetFile最终上传的文件，先判断文件是否存在 File targetFile=new File(uploadUrl+filename); if(!targetFile.exists()){ //如果文件不存在，我们尝试创建它 try { targetFile.createNewFile(); }catch (IOException e){ e.printStackTrace(); } } //使用MultipartFile的transferTo方法保存文件 try { imageFile.transferTo(targetFile); }catch (IllegalStateException e){ e.printStackTrace(); }catch (IOException e){ e.printStackTrace(); } return "img/"+filename; }
