minio教程 给出代码案例 其中包括文件的上传下载 已经上传前的压缩 基于springboot

很好的问题！对于Minio的基本操作，您可以使用MinIO Java Client SDK来实现。这里是一个包括文件上传、下载和压缩的代码示例（基于Spring Boot）：

import io.minio.MinioClient;
import io.minio.errors.*;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

import java.io.IOException;
import java.io.InputStream;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;

@Component
public class MinioService {
    @Value("${minio.accessKey}")
    private String accessKey;
    @Value("${minio.secretKey}")
    private String secretKey;
    @Value("${minio.url}")
    private String url;
    @Value("${minio.bucket-name}")
    private String bucketName;

    private MinioClient generateMinioClient() throws InvalidPortException, InvalidEndpointException {
        return new MinioClient(url, accessKey, secretKey);
    }

    public void uploadFile(String fileName, InputStream inputStream, long size, String contentType) throws IOException, InterruptedException, NoSuchAlgorithmException, InvalidKeyException, InvalidResponseException, ErrorResponseException, RegionConflictException, InsufficientDataException, InternalException {
        MinioClient minioClient = generateMinioClient();
        if(!minioClient.bucketExists(bucketName)) {
            minioClient.makeBucket(bucketName);
        }

        minioClient.putObject(bucketName, fileName, inputStream, size, contentType);
    }

    public InputStream downloadFile(String fileName) throws IOException, InterruptedException, InvalidKeyException, InvalidResponseException, ErrorResponseException, NoSuchAlgorithmException, InvalidArgumentException, InternalException {
        MinioClient minioClient = generateMinioClient();
        return minioClient.getObject(bucketName, fileName);
    }

    public void compressAndUploadFile(String fileName, InputStream inputStream, long size, String contentType) throws IOException, InterruptedException, NoSuchAlgorithmException, InvalidKeyException, InvalidResponseException, ErrorResponseException, RegionConflictException, InsufficientDataException, InternalException {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        ZipOutputStream zipOutputStream = new ZipOutputStream(byteArrayOutputStream);
        ZipEntry zipEntry = new ZipEntry(fileName);

        zipOutputStream.putNextEntry(zipEntry);

        byte[] fileBytes = inputStream.readAllBytes();
        zipOutputStream.write(fileBytes);

        zipOutputStream.closeEntry();
        zipOutputStream.close();

        ByteArrayResource byteArrayResource = new ByteArrayResource(byteArrayOutputStream.toByteArray());
        ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(byteArrayOutputStream.toByteArray());

        uploadFile(fileName + ".zip", byteArrayInputStream, byteArrayResource.contentLength(), contentType);
    }

    public void deleteFile(String fileName) throws IOException, InterruptedException, InvalidKeyException, InvalidResponseException, ErrorResponseException, NoSuchAlgorithmException, InvalidArgumentException, InternalException {
        MinioClient minioClient = generateMinioClient();
        minioClient.removeObject(bucketName, fileName);
    }
}

通过调用 `MinioService` 类中的方法，您可以轻松完成上传、下载和压缩文件的操作。希望这个示例能有所帮助！
