All Implemented Interfaces:

EventBus

public class SpringIntegrationEventBus
extends Object
implements EventBus

EventBus implementation that delegates all subscription and publishing requests to a Spring Integration channel.

Use setChannel(org.springframework.integration.core.SubscribableChannel) to set the channel to delegate all the requests to.

This EventBus will automatically wrap and unwrap events in Messages and EventListeners in MessageHandlers.

This implementation expects the Spring Integration to be configured to handle messages asynchronously.
