如何使用Java在Google云存储中的Blob上设置TTL？

<dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-storage</artifactId>
    <version>版本号</version>
</dependency>

import com.google.cloud.storage.Blob;
import com.google.cloud.storage.BlobInfo;
import com.google.cloud.storage.Storage;
import com.google.cloud.storage.StorageOptions;

// 创建Storage对象
Storage storage = StorageOptions.getDefaultInstance().getService();

String bucketName = "your-bucket-name";
String blobName = "your-blob-name";

BlobId blobId = BlobId.of(bucketName, blobName);
Blob blob = storage.get(blobId);

long ttlMillis = 3600000; // 设置TTL为1小时

BlobInfo updatedInfo = blob.toBuilder()
        .setTemporaryHold(false) // 确保临时保留被禁用
        .setRetentionDuration(ttlMillis)
        .build();

// 更新Blob的信息
storage.update(updatedInfo);
