All Known Implementing Classes:

ServiceAuthenticationImpl

public interface ServiceAuthentication<U>

This service is used to provide authentication managment for a final application. The user type used in the application is needed. This service need to be implemented and build in the AppModule of your application. An abstract implementation is available ServiceAuthenticationAbstract This service is used in AbstractAuthenticationFilter to verify user rights for displaying pages using isAllowed(Class) method. See documentation site for more explanation of using this service and authentication managment.

AppModule contribution : Exemple with MyUser type for user and ServiceAuthenticationImpl for implementation :

  public ServiceAuthentication buildServiceAuthentication(
          ApplicationStateManager stateManager) {
      ServiceAuthentication instance =
              new ServiceAuthenticationImpl(stateManager);
      return instance;
  }
 

Contribute to ApplicationStateManager to instantiate MyUser automatically :

 public void contributeApplicationStateManager(
           MappedConfiguration,
           ApplicationStateContribution> configuration,
           final ServiceAuthentication serviceAuthentication) {
 

      ApplicationStateCreator creator =
              new ApplicationStateCreator() {
