Class StsGetSessionTokenCredentialsProvider

java.lang.Object

software.amazon.awssdk.services.sts.auth.StsGetSessionTokenCredentialsProvider

All Implemented Interfaces:

AutoCloseable, AwsCredentialsProvider, SdkAutoCloseable

@ThreadSafe
public class StsGetSessionTokenCredentialsProvider
extends Object

An implementation of AwsCredentialsProvider that periodically sends a GetSessionTokenRequest to the AWS Security Token Service to maintain short-lived sessions to use for authentication. These sessions are updated asynchronously in the background as they get close to expiring. If the credentials are not successfully updated asynchronously in the background, calls to resolveCredentials() will begin to block in an attempt to update the credentials synchronously. This provider creates a thread in the background to periodically update credentials. If this provider is no longer needed, the background thread can be shut down using close(). This is created using builder().
