当关键字定义为文件夹结构时，我们如何从亚马逊网络服务的s3存储桶中获取对象？Java

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>s3</artifactId>
    <version>2.17.69</version>
</dependency>

import software.amazon.awssdk.auth.credentials.DefaultCredentialsProvider;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.s3.S3Client;

S3Client s3Client = S3Client.builder()
        .region(Region.US_EAST_1) // 设置所在区域
        .credentialsProvider(DefaultCredentialsProvider.create()) // 使用默认凭证提供者
        .build();

import software.amazon.awssdk.services.s3.model.GetObjectRequest;
import software.amazon.awssdk.services.s3.model.S3Object;

String bucketName = "your-bucket-name";
String objectKey = "your-folder-path/object-name.txt";

GetObjectRequest getObjectRequest = GetObjectRequest.builder()
        .bucket(bucketName)
        .key(objectKey)
        .build();

S3Object s3Object = s3Client.getObject(getObjectRequest);
