Override a Notification Type Handler

The Notification Framework allows you to override a notification type handler for a specific message.

To override the handler for a specific message, create a new bean. For example, create a new bean to override the handler for MtxOfferPurchaseNotification in the mtx_notifier_camel.xml configuration file.

<bean id="offerPurchaseNotificationHandler" class="com.matrixx.camelNotifier.misc.OfferPurchaseNotificationHandlerTest" scope="prototype"/>

The following code shows a class that adds an additional value to the body map.

/**

public class OfferPurchaseNotificationHandlerTest extends OfferPurchaseNotificationHandler {
    public static final Logger LOG = LoggerFactory.getLogger(OfferPurchaseNotificationHandlerTest.class);
public OfferPurchaseNotificationHandlerTest(MtxNotification notification, NotifierConfiguration configuration,
            AbstractApplicationContext context, RSGatewayService m_rsGatewaySvc)
    {
        super(notification, configuration, context, m_rsGatewaySvc);

        LOG.info("> OVERRIDE BEAN - Handler");
    }

    @Override
    public Map<String, Object> getNotificationData()
    {
        Map<String, Object> map = super.getNotificationData();
        
        String key = "testCustomizedKey";
        String value = UUID.randomUUID().toString();

        LOG.info("> OVERRIDE BEAN - Handler, adding key=" + key + ", value=" + value);
        
        map.put(key, value);
        
        return map;
    }

}

Use the following to access the new map value in the template: 

...
TEST body.testCustomizedKey=${body.testCustomizedKey}
...

The message format now includes: 

TEST body.testCustomizedKey=1d62c3b6-ffd4-4018-bc88-c1fb0bceea77
