@FunctionalInterface public interface AwsCredentialsProvider
AwsCredentialsthat are used for authentication.
Commonly-used implementations include
StaticCredentialsProvider for a fixed set of credentials and the
DefaultCredentialsProvider for discovering credentials from the host's environment. The AWS Security Token
Service (STS) client also provides implementations of this interface for loading temporary, limited-privilege credentials from
AwsCredentialsthat can be used to authorize an AWS request. Each implementation of AWSCredentialsProvider can chose its own strategy for loading credentials. For example, an implementation might load credentials from an existing key management system, or load new credentials when credentials are rotated.
If an error occurs during the loading of credentials or credentials could not be found, a runtime exception will be raised.
