如何使用 aws-sdk-2.x 从 S3 存储桶中获取 object 的 S3 URL

Question

We were using the AWS Java SDK-1.x version in our application till now. We decided to migrate to the 2.x. As per my analysis I have found out the equivalent function which we are using for 1.x client operation in 2.x in our application. But for some operation I could not able to find matching functions. Below are the details.

1.x (AmazonS3)	2.x (S3AsyncClient)
getObject(String bucket, String key)	getObject(GetObjectRequest req, Path destination)
putObject(String bucket, String key, File file)	putObject(PutObjectRequest req, Path source)
generatePresignedUrl(GeneratePresignedUrlRequest req)	S3PreSigner.presignGetObject(GetObjectPresignRequest req)
deleteObject(String bucket, String key)	deleteObject(DeleteObjectRequest req)
getUrl(String bucket, String key)	?
doesObjectExist(String bucket, String key)	?

Any help or pointer is really appreciated.

Below are the replacements for the methods that you are looking for in 2.x SDK:

1.11.x Operation	2.0 Operation
getUrl	S3Utilities#getUrl
doesObjectExist	headObject

Here is a complete mapping of S3 1.x and 2.0 Operations .
