Class SystemSettingsCredentialsProvider

java.lang.Object
software.amazon.awssdk.auth.credentials.internal.SystemSettingsCredentialsProvider
All Implemented Interfaces:
AwsCredentialsProvider, IdentityProvider<AwsCredentialsIdentity>
Direct Known Subclasses:
EnvironmentVariableCredentialsProvider, SystemPropertyCredentialsProvider
public abstract class SystemSettingsCredentialsProvider extends Object implements AwsCredentialsProvider
Loads credentials providers from the SdkSystemSetting.AWS_ACCESS_KEY_ID, SdkSystemSetting.AWS_SECRET_ACCESS_KEY, and SdkSystemSetting.AWS_SESSION_TOKEN system settings. This does not load the credentials directly. Instead, the actual mapping of setting to credentials is done by child classes. This allows us to separately load the credentials from system properties and environment variables so that customers can remove one or the other from their credential chain, or build a different chain with these pieces of functionality separated.

      public AwsCredentials resolveCredentials()
      Description copied from interface: AwsCredentialsProvider
      Returns AwsCredentials that can be used to authorize an AWS request. Each implementation of AWSCredentialsProvider can choose 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.

      Specified by:
      resolveCredentials in interface AwsCredentialsProvider

      AwsCredentials which the caller can use to authorize an AWS request.
