检查文件类型，先为pom.xml 添加第三方依赖:jmimemagic 类包

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

Spring 之MultipartFile转换File 并鉴别File Mine Type 类型核心功能代码:

public boolean checkFileType(MultipartFile uploadFile){
		 //文件名
        String fileName = uploadFile.getOriginalFilename();
        // 获取文件后缀
        String suffix=fileName.substring(fileName.lastIndexOf("."));
        File picFile = null;
        try {
            // 用uuid作为文件名，防止生成的临时文件重复
            picFile = File.createTempFile(String.valueOf(idGenerator.nextId()), suffix);
            FileUtils.copyInputStreamToFile(uploadFile.getInputStream(),picFile);
            // MultipartFile to File
            MagicMatch match = Magic.getMagicMatch(picFile, false);
            String mimeType = match.getMimeType();
            // 白名单匹配
            boolean anyMatch = Arrays.stream(mimeTypeWhiteList).anyMatch(x -> x.equalsIgnoreCase(mimeType));
            return anyMatch;
 
        } catch (IOException e) {
            System.out.println("生成临时文件异常");
            logger.error("error: {}", e.getMessage(), e);
        } catch (Exception e) {
        	System.out.println("MIME-TYPE检查发生异常");
        	logger.error("error: {}", e.getMessage(), e);
        } finally {
            //程序结束时，删除临时文件
            if (picFile.exists()){
                picFile.delete();
            }
        }

		return false;
	}

改业务功能代码应用于文件上传功能:

/**
	 * 通用文件上传功能; 备注：文件大小<=30M,如果超出规定文件大小,建议采用大文件上传
	 * 
	 * @param entity
	 * @return
	 */
	@RequestMapping(value = "/fileUpload", method = { RequestMethod.POST })
	@ResponseBody
	@ApiOperation(httpMethod = "POST", value = "文件上传(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("上传电子包文件格式不支持,本项目仅支持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 block
			 logger.error("error: {}", e.getMessage(), e);
		}
		return Result.ok("文件上传成功").setDatas("model", model);
	}
