Intershop 7.10. - fetching payment configuration - service

Question

We would like to fetch the payment configuration from Order in Java class (OrderBO extension). So far we have managed to fetch the service like this:
final OrderBOPaymentExtension<OrderBO> paymentExtension = getExtendedObject().getExtension(OrderBOPaymentExtension.EXTENSION_ID);
final PaymentBO paymentBO = paymentExtension.getPaymentBOs().stream().findFirst().orElse(null);
PaymentServiceBO paymentServiceBO = paymentBO.getPaymentServiceBO();
Now we need to fetch the configuration, so we can read certain configuration parameters from the payment method. What is the best way to do that?
We know it is possible to fetch the payment configuration through the PO Factory like this:
PaymentConfigurationPOFactory f = (PaymentConfigurationPOFactory)NamingMgr.getInstance().lookupFactory(PaymentConfigurationPO.class);
PaymentConfigurationPO r = f.getConfigForIDAndDomain(iD, domain);
But we would like to avoid using deprecated code.
UPDATE:
What we are trying to achieve is access these BO parameters in Java code:

Answer 1

I'd suggest you write a PaymentServiceBO extension. Within that extension you can write getter methods to query for certain config values. The java code for accessing service configuration object is:
PaymentConfiguration paymentConfig = paymentServiceBO.getExtension(PersistentObjectBOExtension.class).getPersistentObject();
ServiceConfigurationBO serviceConfigurationBO = repository.getServiceConfigurationBOByID(paymentConfig.getManagedServiceConfiguration().getUUID());
ConfigurationProvider configProviderExtension = serviceConfigurationBO.getExtension(ConfigurationProvider.class);
Configuration configuration = configProviderExtension.getConfiguration();
Logger.debug(this, "payment service config keys = {}", configuration.getKeys());

Answer 2

I believe PaymentConfiguration is deprecated. See PaymentConfigurationBO javadoc:
Deprecated since 7.6. Payment configurations are now represented via PaymentServiceBOs.
So you need to use PaymentServiceBO methods or write a business object extension that does what you want.
