我如何使用Java上传文件夹到亚马逊网络服务S3？

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>s3</artifactId>
    <version>2.17.0</version>
</dependency>

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

public class S3Uploader {
    public static void main(String[] args) {
        String accessKey = "YOUR_ACCESS_KEY";
        String secretKey = "YOUR_SECRET_KEY";
        Region region = Region.US_EAST_1; // 根据你的S3存储桶所在地区选择合适的Region

        AwsCredentials credentials = AwsBasicCredentials.create(accessKey, secretKey);
        S3Client s3Client = S3Client.builder()
                .region(region)
                .credentialsProvider(StaticCredentialsProvider.create(credentials))
                .build();

        // 在这里进行文件上传操作
    }
}

import software.amazon.awssdk.services.s3.model.PutObjectRequest;
import software.amazon.awssdk.services.s3.model.PutObjectResponse;

import java.io.File;
import java.nio.file.Path;
import java.nio.file.Paths;

public class S3Uploader {
    public static void main(String[] args) {
        // ...

        String bucketName = "YOUR_BUCKET_NAME";
        String folderPath = "YOUR_FOLDER_PATH"; // 要上传的文件夹路径

        File folder = new File(folderPath);
        if (folder.isDirectory()) {
            for (File file : folder.listFiles()) {
                String key = file.getName();
                Path filePath = Paths.get(file.getAbsolutePath());

                PutObjectRequest request = PutObjectRequest.builder()
                        .bucket(bucketName)
                        .key(key)
                        .build();

                PutObjectResponse response = s3Client.putObject(request, filePath);
                System.out.println("Uploaded file: " + key);
            }
        }

        // ...
    }
}
