Spring Integration manually start/stop channel adapter via control bus

Question

Is there anyway to manually start/init a channel adapter?

I have two pairs of inbound/outbound adapters in my context.xml and would like to decide at runtime which o

Answer 1

Set autoStartup="false" and either directly start()/stop() them, or use a (send @myAdapter.start()).

Getting a direct reference (autowire etc), depends on the endpoint type. If it's a polled endpoint, inject a SourcePollingChannelAdapter; message-driven adapters vary, but generally are a MessageProducerSupport or MessagingGatewaySupport.

EDIT:

Read about the control-bus here.

Give the inbound adapter an id attribute.

Create a gateway interface

public interface Controller {

    void control(String command);

}

@Autowire the gateway (or use context.getBean(Controller.class)).

Then, when you are ready to start the adapter, call, e.g. gateway.control("@mqttOut.start()").

You don't need auto-startup="false" on the outbound adapters.

However, for a simple use case like this, you might want to investigate using Spring profiles instead (put the adapters in a profile and enable the profile at runtime.
