Minio 整合springboot 开发实现文件上传

Minio 作为对象存储，灵活方便，结合java 实现minio 文件上传

1.搭建maven环境，添加依赖包

<properties>
        <minio.version>4.0.0</minio.version>
    </properties>
    <dependency>
        <groupId>io.minio</groupId>
        <artifactId>minio</artifactId>
        <version>${minio.version}</version>
    </dependency>

2.书写一个MinioUtils

public class MinioClientUtils {
    
        private static final Logger LOGGER = LoggerFactory.getLogger(MinioClientUtils.class);
    
        private static MinioClientUtils minioClientUtils;
    
        private MinioClient minioClient;
    
        private static int RETRY_NUM = 3;
    
        private static final String bucketPublicPolicy = "{\"Version\":\"2012-10-17\",\"Statement\":[{\"Action\":[\"s3:GetBucketLocation\",\"s3:ListBucket\",\"s3:ListBucketMultipartUploads\"],\"Effect\":\"Allow\",\"Principal\":{\"AWS\":[\"*\"]},\"Resource\":[\"arn:aws:s3:::test\"],\"Sid\":\"\"},{\"Action\":[\"s3:AbortMultipartUpload\",\"s3:DeleteObject\",\"s3:GetObject\",\"s3:ListMultipartUploadParts\",\"s3:PutObject\"],\"Effect\":\"Allow\",\"Principal\":{\"AWS\":[\"*\"]},\"Resource\":[\"arn:aws:s3:::test/*\"],\"Sid\":\"\"}]}";
    
        public static MinioClientUtils getInstance() {
            if (null != minioClientUtils) {
                return minioClientUtils;
            }
            synchronized (MinioClientUtils.class) {
                if (null == minioClientUtils) {
                    minioClientUtils = new MinioClientUtils();
                }
            }
            return minioClientUtils;
        }
    
    
        private MinioClientUtils() {
            init();
        }
    
        private void init() {
            final Configuration configuration = initConfiguration();
            String url = configuration.getString("minio.url", StringUtils.EMPTY);
            String username = configuration.getString("minio.name", StringUtils.EMPTY);
            String password = configuration.getString("minio.password", StringUtils.EMPTY);

                    minioClient = new MinioClient(url, username, password, false);
                }
            } catch (Exception e) {
                LOGGER.error("restClient.close occur error", e);
            }
    
        }
    
        public boolean createBucketPublic(String bucketName) {
            boolean isCreated;
            try {

3.工具类已经封装各种上传。

public void upload(@RequestParam("file") MulipartFile data,String bucketName,String path){
    String fileName = data.getOriginalFilename();
    String filePath = path+"/"+fileName;
    String contentType = data.getContentType();
    InputStream inputStram = data.getInputStream();
    MinioClientUtils minioClientUtils = MinioCLinetUtils.getInstance();
    minioClientUtils.uploadStream(
    bucketName,
    filePath,
    inputStream,
    contentType
    );
    
    }
