要在Java S3Client中复制对象跨区域,您需要执行以下步骤:

1. 创建S3Client对象并设置源和目标区域:

```
AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
                    .withRegion(sourceRegion)
                    .build();

Region destinationRegion = Region.getRegion(destinationRegionName);
s3Client.setRegion(destinationRegion);
```

2. 使用S3Client的copyObject方法复制对象:

```
CopyObjectRequest copyObjectRequest = new CopyObjectRequest(sourceBucketName, sourceKey, destinationBucketName, destinationKey);
s3Client.copyObject(copyObjectRequest);
```

3. 如果需要,您可以设置其他选项,例如ACL和元数据:

```
AccessControlList acl = s3Client.getObjectAcl(sourceBucketName, sourceKey);
CopyObjectRequest copyObjectRequest = new CopyObjectRequest(sourceBucketName, sourceKey, destinationBucketName, destinationKey)
                    .withAccessControlList(acl)
                    .withMetadata(metadata);
s3Client.copyObject(copyObjectRequest);
```

注意:在复制对象时,源和目标区域必须是不同的。否则,您将收到“源和目标区域相同”的错误消息。
