SpringBoot 使用minio实现异步分片上传、秒传、续传

使用Spring Boot和MinIO实现异步分片上传、秒传和续传的示例代码。

首先,确保您的Spring Boot项目已正确配置和集成了MinIO SDK。然后,您可以按照以下步骤实现所需功能:

 

  • 异步分片上传:
import io.minio.MinioClient;
import io.minio.ObjectWriteResponse;
import io.minio.PutObjectOptions;
import io.minio.errors.MinioException;
import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Component;
import org.springframework.web.multipart.MultipartFile;

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

@Component
public class MinioUploader {

    private final MinioClient minioClient;
    private static final String BUCKET_NAME = "your-bucket-name";

    public MinioUploader(MinioClient minioClient) {
        this.minioClient = minioClient;
    }

    @Async
    public void uploadFileAsync(MultipartFile file, String objectName) {
        try {
            PutObjectOptions options = new PutObjectOptions(file.getSize(), -1);
            options.setContentType(file.getContentType());
            ObjectWriteResponse response = minioClient.putObject(BUCKET_NAME, objectName, file.getInputStream(), options);
            // 分片上传完成后的操作
            System.out.println("File uploaded successfully. Object name: " + response.object());
        } catch (MinioException | IOException | NoSuchAlgorithmException | InvalidKeyException e) {
            // 处理异常
        }
    }
}
  • 秒传检查:

import io.minio.MinioClient;
import io.minio.ObjectStat;
import io.minio.errors.MinioException;
import org.springframework.stereotype.Component;

@Component
public class MinioChecker {

    private final MinioClient minioClient;
    private static final String BUCKET_NAME = "your-bucket-name";

    public MinioChecker(MinioClient minioClient) {
        this.minioClient = minioClient;
    }

    public boolean isObjectExists(String objectName) {
        try {
            ObjectStat objectStat = minioClient.statObject(BUCKET_NAME, objectName);
            return objectStat != null;
        } catch (MinioException e) {
            // 处理异常
        }
        return false;
    }
}
  • 续传功能:

请注意,以上代码仅为示例,您需要根据您的具体需求进行适当的调整和错误处理。确保您正确配置了MinIO的连接信息和权限,并根据您的Bucket名称进行相应的更改。

希望这可以帮助您开始使用Spring Boot和MinIO实现异步分片上传、秒传和续传的功能。如有任何问题,请随时关注公众号提问。
