Create a Spring Integration Channel programatically and register that as a Spring bean

DynamicServiceActivator.java

private SubscribableChannel createInputChannel(String inputChannelName) {
		PublishSubscribeChannel channel = new PublishSubscribeChannel();
		channel.setBeanName(inputChannelName);
		channel.setBeanFactory(applicationContext);
		//channel.setApplySequence(true);
		((ConfigurableApplicationContext)applicationContext).getBeanFactory().registerSingleton(inputChannelName, channel);
		return channel;
	}
