檢查文件類型，先為pom.xml 添加第三方依賴:jmimemagic?類包

<dependency><groupId>net.sf.jmimemagic</groupId><artifactId>jmimemagic</artifactId><version>0.1.5</version></dependency>

Spring 之MultipartFile轉換File 并鑒別File Mine Type 類型 核心功能代碼:

public boolean checkFileType(MultipartFile uploadFile){//文件名String fileName = uploadFile.getOriginalFilename();// 獲取文件后綴String suffix=fileName.substring(fileName.lastIndexOf("."));File picFile = null;try {// 用uuid作為文件名，防止生成的臨時文件重復picFile = File.createTempFile(String.valueOf(idGenerator.nextId()), suffix);FileUtils.copyInputStreamToFile(uploadFile.getInputStream(),picFile);// MultipartFile to FileMagicMatch match = Magic.getMagicMatch(picFile, false);String mimeType = match.getMimeType();// 白名單匹配boolean anyMatch = Arrays.stream(mimeTypeWhiteList).anyMatch(x -> x.equalsIgnoreCase(mimeType));return anyMatch;} catch (IOException e) {System.out.println("生成臨時文件異常");logger.error("error: {}", e.getMessage(), e);} catch (Exception e) {System.out.println("MIME-TYPE檢查發生異常");logger.error("error: {}", e.getMessage(), e);} finally {//程序結束時，刪除臨時文件if (picFile.exists()){picFile.delete();}}return false;}

改業務功能代碼應用于文件上傳功能:

/*** 通用文件上傳功能; 備注：文件大小<=30M,如果超出規定文件大小,建議采用大文件上傳* * @param entity* @return*/@RequestMapping(value = "/fileUpload", method = { RequestMethod.POST })@ResponseBody@ApiOperation(httpMethod = "POST", value = "文件上傳(小于等于30M)")public Result upload(ChunkInfoModel entity) {if (logger.isDebugEnabled()) {logger.debug(entity.toString());}boolean target = checkFileType(entity.getFile());if(!target){return Result.error("上傳電子包文件格式不支持,本項目僅支持zip格式");}SysEfileInfo model = null;try {String folder = null;if(StringUtils.isEmpty(entity.getFolder())){folder = "default";} else {folder = entity.getFolder();}model = upload.smallAttachUpload(entity, folder);} catch (Exception e) {// TODO Auto-generated catch blocklogger.error("error: {}", e.getMessage(), e);}return Result.ok("文件上傳成功").setDatas("model", model);}
