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);

        try {
            if (StringUtils.isNotEmpty(url) && StringUtils.isNotEmpty(username) && StringUtils.isNotEmpty(password)) {
                minioClient = new MinioClient(url, username, password, false);
            }
        } catch (Exception e) {
            LOGGER.error("restClient.close occur error", e);
        }

    }

}

}
3.工具类已经封装各种上传。
4.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

);

}
