spring mvc 批量上传+文件上传
简单3步走。搞定！
上传文件成功后：
1 上传文件核心方法
public static String saveWebImgFile(MultipartFile imgFile){ String webFilePath = ""; if(imgFile.getSize() > 0 && isImage(imgFile.getContentType())){ FileOutputStream fos = null; try { byte[] b = imgFile.getBytes(); /* 构造文件路径 */ String webRoot = PathUtil.classPath(); SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd"); SimpleDateFormat sdf2 = new SimpleDateFormat("HHmmssSSS"); String datePath = sdf.format(new Date()); String datePath2 = sdf2.format(new Date()); String dirPath = webRoot + "/../../upload/img/" + datePath; File dir = new File(dirPath); if(!dir.exists()){ dir.mkdirs(); } String fileName = imgFile.getOriginalFilename(); String filePath = dirPath + "/" + datePath2 + getImgSuffix(fileName); webFilePath = "/upload/img/" + datePath + "/" + datePath2 + getImgSuffix(fileName); File file = new File(filePath); dir.setWritable(true); file.setWritable(true); fos = new FileOutputStream(file); fos.write(b); } catch (IOException e) { throw new RuntimeException("文件上传失败！" ,e); }finally{ if(fos != null){ try { fos.close(); } catch (IOException e) { throw new RuntimeException("文件上传->输出流关闭失败！！！！" ,e); } } } } return webFilePath; }
@RequestMapping(value = "/imgupload") public String handleFormUpload(MultipartHttpServletRequest request) throws Exception{ List<MultipartFile> files = request.getFiles("file"); Map<String, String> imgs = new HashMap<String, String>(); for (int i = 0; i < files.size(); i++) { String webpath = FileUtil.saveWebImgFile(files.get(i)); imgs.put("img"+i, webpath); } request.setAttribute("imgs", imgs); return showImageList(request); }
3 页面代码
<body> 商品图片设置： <form method="post" enctype="multipart/form-data" action="product/imgupload" name="imagefrm"> <table> <tr> <td>商品大图：默认宽度600px,高度600px</td> </tr> <tr> <td><input type="file" name="file"/><c:if test="${imgs.img0!=null&&imgs.img0!=''}"><img src="<%=basePath %>${imgs.img0 }" style="width:40;height:40px;"/></c:if></td> </tr> <tr> <td>添加多角度图片：默认宽度50px,高度50px</td> </tr> <tr> <td><input type="file" name="file"/><c:if test="${imgs.img1!=null&&imgs.img1!=''}"><img src="<%=basePath %>${imgs.img1 }" style="width:40;height:40px;"/></c:if></td> </tr> <tr> <td><input type="file" name="file"/><c:if test="${imgs.img2!=null&&imgs.img2!=''}"><img src="<%=basePath %>${imgs.img2 }" style="width:40;height:40px;"/></c:if></td> </tr> <tr> <td><input type="file" name="file"/><c:if test="${imgs.img3!=null&&imgs.img3!=''}"><img src="<%=basePath %>${imgs.img3 }" style="width:40;height:40px;"/></c:if></td> </tr> <tr> <td><input type="file" name="file"/><c:if test="${imgs.img4!=null&&imgs.img4!=''}"><img src="<%=basePath %>${imgs.img4 }" style="width:40;height:40px;"/></c:if></td> </tr> <tr> <td><input type="submit" value="上传所有图片"/></td> </tr> </table> </form> </body>
