【分布式云储存】Springboot微服务接入MinIO实现文件服务

以下是一个简化的Spring Boot微服务接入MinIO实现文件服务的代码示例：

@Configuration
public class MinioConfig {
    @Value("${minio.url}")
    private String url;
 
    @Value("${minio.accessKey}")
    private String accessKey;
 
    @Value("${minio.secretKey}")
    private String secretKey;
 
    @Bean
    public MinioClient minioClient() throws InvalidPortException, InvalidEndpointException, InvalidBucketNameException, InsufficientDataException, ErrorResponseException, IOException, NoSuchAlgorithmException, InvalidKeyException, XmlParserException {
        return new MinioClient(url, accessKey, secretKey);
    }
}
 
@Service
public class MinioService {
    @Autowired
    private MinioClient minioClient;
 
    public boolean bucketExists(String bucketName) throws IOException, NoSuchAlgorithmException, InvalidKeyException, XmlParserException {
        boolean isExist = minioClient.bucketExists(bucketName);
        return isExist;
    }
 
    public void createBucket(String bucketName) throws IOException, NoSuchAlgorithmException, InvalidKeyException, XmlParserException {
        minioClient.makeBucket(bucketName);
    }
 
    public void uploadFile(MultipartFile file, String bucketName, String objectName) throws IOException, NoSuchAlgorithmException, InvalidKeyException, XmlParserException {
        minioClient.putObject(bucketName, objectName, file.getInputStream(), file.getContentType());
    }
 
    public Stream<Path> loadFile(String bucketName, String objectName) throws IOException, NoSuchAlgorithmException, InvalidKeyException, XmlParserException {
        InputStream inputStream = minioClient.getObject(bucketName, objectName);
        return IOUtils.toBuffered(inputStream).lines().onClose(() -> {
            try {
                inputStream.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        });
    }
}
 
@RestController
public class MinioController {
    @Autowired
    private MinioService minioService;
 
    @PostMapping("/upload")
    public ResponseEntity<?> uploadFile(@RequestParam("file") MultipartFile file, @RequestParam("bucket") String bucket, @RequestParam("object") String object) {
        try {
            minioService.uploadFile(file, bucket, o
