Session credentials periodically refreshed by AWS SecurityTokenService.

Calls to getAWSAccessKeyId(), getAWSSecretKey(), and getSessionToken() should be synchronized on this object to prevent races on the boundary of session expiration. Alternately, clients can call getImmutableCredentials() to ensure a consistent set of access key, secret key, and token.

This class is deprecated and should not be used anymore. Instead, use STSSessionCredentialsProvider.

 
 
     private final int sessionDurationSeconds;
 
     private Credentials sessionCredentials;
 
     public static final int DEFAULT_DURATION_SECONDS = 3600;

    
Create a new credentials object that will periodically and automatically obtain a session from STS.

Parameters:
credentials Primary AWS account credentials.
 
     public STSSessionCredentials(AWSCredentials credentials) {
         this(credentials);
     }

Create a new credentials object that will periodically and automatically obtain a session from STS.

Parameters:
credentials Primary AWS account credentials.
sessionDurationSeconds The duration, in seconds, for each session to last.
 
     public STSSessionCredentials(AWSCredentials credentialsint sessionDurationSeconds) {
         this. = new AWSSecurityTokenServiceClient(credentials);
         this. = sessionDurationSeconds;
     }

    
Create a new credentials object that will periodically and automatically obtain a session from STS, using a preconfigured STS client.

Parameters:
stsClient A pre-configured STS client from which to get credentials.
 
     public STSSessionCredentials(AWSSecurityTokenService stsClient) {
         this(stsClient);
     }

    
Create a new credentials object that will periodically and automatically obtain a session from STS, using a preconfigured STS client.

Parameters:
stsClient A pre-configured STS client from which to get credentials.
settings Session settings for all sessions created
 
     public STSSessionCredentials(AWSSecurityTokenService stsClientint sessionDuratinSeconds) {
         this. = stsClient;
         this. = sessionDuratinSeconds;
     }

    
Returns the AWS access key for the current STS session, beginning a new one if necessary.

Clients are encouraged to call the atomic RenewableAWSSessionCredentials#getImmutableCredentials() as a proxy to this method.

    @Override
    public synchronized String getAWSAccessKeyId() {
        return getSessionCredentials().getAccessKeyId();
    }

    
Returns the AWS secret key for the current STS session, beginning a new one if necessary.

Clients are encouraged to call the atomic RenewableAWSSessionCredentials#getImmutableCredentials() as a proxy to this method.

    @Override
    public synchronized String getAWSSecretKey() {
        return getSessionCredentials().getSecretAccessKey();
    }

    
Returns the session token for the current STS session, beginning a new one if necessary.

Clients are encouraged to call the atomic RenewableAWSSessionCredentials#getImmutableCredentials() as a proxy to this method.

    @Override
    public synchronized String getSessionToken() {
        return getSessionCredentials().getSessionToken();
    }

    
Returns immutable session credentials for this session, beginning a new one if necessary.
    public synchronized AWSSessionCredentials getImmutableCredentials() {
        Credentials creds = getSessionCredentials();
        return new BasicSessionCredentials(creds.getAccessKeyId(), creds.getSecretAccessKey(), creds.getSessionToken());
    }

    
Refreshes the session credentials from STS.
    @Override
    public synchronized void refreshCredentials() {
        GetSessionTokenResult sessionTokenResult = 
         = sessionTokenResult.getCredentials();
    }

    
Gets a current session credentials object, reinitializing if necessary.
    private synchronized Credentials getSessionCredentials() {
        if ( needsNewSession() )
            refreshCredentials();
        return ;
    }
    private boolean needsNewSession() {
        if (  == null )
            return true;
        Date expiration = .getExpiration();
        long timeRemaining = expiration.getTime() - System.currentTimeMillis();
        if ( timeRemaining < (60 * 1000) )
            return true;
        return false;
    }
