我正在开发一个Sping Boot 应用程序，并将其与Amazon S3 Bucket连接。这是一个用于在AWS上上传视频的简单应用程序。
视频服务类

@Service
@RequiredArgsConstructor
public class VideoService {

    private final S3Service s3Service;
    private final VideoRepository videoRepository;

    public void uploadFile(MultipartFile file)
    {
        String videoURL = s3Service.uploadFile(file);

        var video = new Video();
        video.setVideoUrl(videoURL);

        videoRepository.save(video);

    }
}

服务类别

@Service
@RequiredArgsConstructor
public class S3Service implements FileService{

    public static final String BUCKET_NAME = "****";

    private final AmazonS3Client amazonS3Client;


    @Override
    public String uploadFile(MultipartFile file) {
        var filenameExtension = StringUtils.getFilenameExtension(file.getOriginalFilename());

        var key = UUID.randomUUID().toString() + "." + filenameExtension;

        var metadata = new ObjectMetadata();
        metadata.setContentLength(file.getSize());
        metadata.setContentType(file.getContentType());

        try {
            amazonS3Client.putObject(BUCKET_NAME, key, file.getInputStream(), metadata);
        } catch (IOException ioException) {
            throw new ResponseStatusException(HttpStatus.INTERNAL_SERVER_ERROR,
                    "An Exception occured while uploading the file");
        }

        amazonS3Client.setObjectAcl(BUCKET_NAME, key, CannedAccessControlList.PublicRead);

        return amazonS3Client.getResourceUrl(BUCKET_NAME, key);
    }
}

控制器类：

@RestController
@RequestMapping("/api/videos")
@RequiredArgsConstructor
public class VideoController {

    private final VideoService videoService;

    @PostMapping
    @ResponseStatus(HttpStatus.CREATED)
    public void uploadVideo(@RequestParam("file")MultipartFile file)
    {
        videoService.uploadFile(file);
    }
}

我已经在AWS上创建了s3存储桶和访问密钥
访问密钥和保密密钥存储在VM选项中：- 数据云.aws.凭据.访问密钥=-数据云.aws.凭据.密钥=
这就是我在《 Postman 》里看到的Postman
这在浏览器中显示：Browser localhost
我错过什么了吗？
我按照一个教程，并检查了每一个单独的代码与完成的仓库和一切都是一样的。而不是给我200状态，它给我401状态。
