For best practices, explicitly close a client by calling the close method. Now we have the service client bean ready, which we can inject into a service and start uploading an object to S3 bucket with specified keyname. S3Client exposes S3Utilities object that can be used to create the utilities class that heps us with getting URL for a given S3 object. We can compose a GetObjectRequest using builder pattern specifying the bucket name and key and then use s3 service client to get the object and save it into a byte array or file.

If object content is too big, you can directly stream it into a file without loading inmemory. No need to specify the version for service client libraries. Value; import org. Bean; import org. Configuration; import software. AmazonClientException; import com.
