oss对象上传文件设置格式

@PostMapping("upload")@ApiOperation(value = "上传文件")public Result<UploadDTO> upload(@RequestParam("file") MultipartFile file) throws Exception {if (file.isEmpty()) {return new Result<UploadDTO>().error(ModuleErrorCode.UPLOAD_FILE_EMPTY);}//上传文件String extension = FilenameUtils.getExtension(file.getOriginalFilename());String url = OssFactory.build().uploadSuffix(file.getBytes(), extension);//获取文件名字String fileName = file.getOriginalFilename();//保存文件信息OssEntity ossEntity = new OssEntity();ossEntity.setUrl(url);ossEntity.setCreateDate(new Date());ossEntity.setFileName(fileName);ossService.insert(ossEntity);//文件信息UploadDTO dto = new UploadDTO();dto.setUrl(url);dto.setSize(file.getSize());dto.setFileName(fileName);return new Result<UploadDTO>().ok(dto);}

public String upload(InputStream inputStream, String path) {try {//如果BucketName不存在，则创建boolean found = minioClient.bucketExists(BucketExistsArgs.builder().bucket(config.getMinioBucketName()).build());if (!found) {minioClient.makeBucket(MakeBucketArgs.builder().bucket(config.getMinioBucketName()).build());}minioClient.putObject(PutObjectArgs.builder().bucket(config.getMinioBucketName()).object(path).contentType("image/jpg").contentType("application/pdf").contentType("image/gif").contentType("image/png").contentType("application/vnd.openxmlformats-officedocument.wordprocessingml.document").stream(inputStream, inputStream.available(), -1).build());} catch (Exception e) {throw new RenException(ModuleErrorCode.OSS_UPLOAD_FILE_ERROR, e, "");}return config.getMinioEndPoint() + "/" + config.getMinioBucketName() + "/" + path;}

使用minio上传文件

• 在不设置内容类型,都是只能下载后才能查看
• 如果设置内容类型,只有图片能预览,其他文档类型的只能下载,入宫要上传文档格式,也是需要设置文档的格式的,否则就下载不了了
