I have a consumer method with
@StreamListener(target = Sink.INPUT) method()
And I have a method with an event listener
@EventListener(ApplicationReadyEvent.class) method()...
Is it possible to configure @StreamListener to start listening only after @EventListener method is completed?

According to Spring Cloud Stream docs you could use property spring.cloud.stream.bindings.<bindingName>.consumer.autoStartup=false
which will stop BindingService
from starting automatically starting consumer binding. Then you can do it yourself whenever you need, e.g. in ApplicationReadyEvent
listener.
public class DelayedBindingStarter { private final BindingsEndpoint bindingsEndpoint; @EventListener(ApplicationReadyEvent.class) public void applicationReady() { bindingsEndpoint.changeState("binding_name", BindingsLifecycleController.State.STARTED); }
}
