Google Sheets java sdk oAuth unbefugter nach einigen Stunden (Feder-Boot)

Question

ich erfolgreich eine Feder Boot Serviceclass, um auf Google Blätter, nach den Java Quistart Tutorial for Sheets API

Mein Problem ist, zu schreiben erstellt, dass die Zulassung nicht erneuert, so dass nach die erste erfolgreiche Authentifizierung per Browser, nach einigen Stunden bekomme ich 401 nicht mehr autorisiert. Wie kann ich den Token automatisch erneuern, ohne die Browseranmeldung erneut zu erteilen?

Unter dem Code, danke im voraus

    } 

} 

Edit:

Löste das Build von GoogleAuthorizationCodeFlow Objekt wie folgt ändern:

GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(this.httpTransport, this.jsonFactory, 
      clientSecrets, this.scopes).setDataStoreFactory(this.dataStoreFactory).setAccessType("offline") 
        .setApprovalPrompt("force") 
        .addRefreshListener(
          new DataStoreCredentialRefreshListener(credentialUserId, this.dataStoreFactory)) 
        .build(); 

Answer 1

Es ist ein Konzept, Aktualisierungs-Token genannt und es scheint, als ob es Ihren Bedürfnissen entspricht.

Sie können in dieser Frage gut Discribe finden: https://stackoverflow.com/a/7209263/4988996

Edit: Nach Ihrem Kommentar fand ich, dass Google DataStoreCredentialRefreshListener

Zugriff auf geschützte Ressourcen unter Verwendung des Credential hat. Abgelaufene Zugriffstoken werden ggf. automatisch mit dem Aktualisierungstoken aktualisiert. Stellen Sie sicher, dass Sie DataStoreCredentialRefreshListener verwenden und für die Berechtigung mithilfe von Credential.Builder.addRefreshListener (CredentialRefreshListener) festlegen.

Kasse: https://developers.google.com/api-client-library/java/google-oauth-java-client/oauth2

static void addDataStoreCredentialRefreshListener( Credential.Builder credentialBuilder, String userId, DataStoreFactory dataStoreFactory) throws IOException { credentialBuilder.addRefreshListener( new DataStoreCredentialRefreshListener(userId, dataStoreFactory)); }
