常见 MIME 类型列表

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); 
	}
