In Amazon S3, I have created 1 bucket under that bucket multiple subfolders like <bucket_name>/<year>/<month>/<day>/files (i.e.objects).
在Amazon S3中，我在该存储桶下创建了1个存储桶，其中包含多个子文件夹，如
I want functionality where on request I can download bulk objects by year / month / day, all files in zip.
我希望功能可以根据要求我按年/月/日下载批量对象，所有文件都是zip。
Is there any way I can do this by Amazon Java SDK?
我有什么办法可以通过Amazon Java SDK实现这一目标吗？

There is a MultipleFileDownload method provided with the Transfer Manager library that provides Multiple file download of an entire virtual directory. The contents, however, is not zipped.
Transfer Manager库提供了一个MultipleFileDownload方法，该方法提供整个虚拟目录的多个文件下载。但是，内容不是压缩的。
See: MultipleFileDownload javadoc

Since your objects are in directories by year/month/day, you could use this method to download all files in a specific path. However, the files would not be zipped.
由于您的对象按年/月/日显示在目录中，因此您可以使用此方法下载特定路径中的所有文件。但是，文件不会被压缩。

You can achieve it using mc tool: mc cp -r https://bucketName.s3.amazonaws.com/<year>/<month>/<day> backupdir it copies from S3 to the local directory backup
您可以使用mc工具实现它：mc cp -r https://bucketName.s3.amazonaws.com/
and then you can zip the backup directory by: zip backupdir.zip -r backupdir
然后你可以通过以下方式压缩备份目录：zip backupdir.zip -r backupdir
