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);
}
