如何在java中将S3对象列表从一个文件夹移动/复制到文件夹？

import software.amazon.awssdk.auth.credentials.DefaultCredentialsProvider;

public class S3ObjectMoveCopyExample {
    public static void main(String[] args) {
        String sourceBucket = "your-source-bucket";
        String destinationBucket = "your-destination-bucket";
        String sourceFolder = "source-folder/";
        String destinationFolder = "destination-folder/";

        // 创建S3客户端
        S3Client s3Client = S3Client.builder()
                .region(Region.US_EAST_1) // 设置合适的区域
                .credentialsProvider(DefaultCredentialsProvider.create())
                .build();

        // 列出源文件夹下的所有对象
        ListObjectsV2Request listRequest = ListObjectsV2Request.builder()
                .bucket(sourceBucket)
                .prefix(sourceFolder)
                .build();
        ListObjectsV2Response listResponse = s3Client.listObjectsV2(listRequest);
        List<S3Object> objects = listResponse.contents();

        // 遍历对象列表，逐个移动或复制到目标文件夹
        for (S3Object object : objects) {
            String key = object.key();
            String newKey = key.replace(sourceFolder, destinationFolder);

            // 移动对象
            CopyObjectRequest copyRequest = CopyObjectRequest.builder()
                    .copySource(sourceBucket + "/" + key)
                    .destinationBucket(destinationBucket)
                    .destinationKey(newKey)
                    .build();
            CopyObjectResponse copyResponse = s3Client.copyObject(copyRequest);

            // 如果需要删除源文件夹下的对象，可以添加以下代码
            // DeleteObjectRequest deleteRequest = DeleteObjectRequest.builder()
            //         .bucket(sourceBucket)
            //         .key(key)
            //         .build();
            // s3Client.deleteObject(deleteRequest);
        }

        System.out.println("移动/复制完成");
    }
