Eventing-style interactions involve a component that acts as a source or producer of events which are dispatched to a channel. In turn, consumer components are configured to listen on a channel for events. Similar to reference injection, a source component is injected with a producer proxy using the Fabric3 @Producer annotation. This proxy is responsible for dispatching messages to a channel. A component subscribes to a channel using a consumer method.

The following is an example of a source component with a an injected producer:

import org.fabric3.api.annotation.Producer;

public class BuyComponent implements BuyService {

   @Producer
   private BuyChannel buyChannel;

   public void process() {
      BuyEvent event = ...
      buyChannel.publish(event);*
   }
}
