What is the best practice to implement Request-Reply style message handling in SI?

[xml2008]

I am using Spring Integration in a Spring MVC controller context, and I need implementing Request/Reply style message interaction.

The code is as follows:

private void processWithTempReplyChannel(HttpServletRequest request, ModelMap model) {
		ApplicationContext applicationContext = (ApplicationContext) getApplicationContext();
		//context.start();

		ATransaction aTransaction = new ATransactionImpl();
		acordTransaction.setRequestMessage(request.getParameter("requestMessage"));

		ChannelRegistry channelRegistry = (ChannelRegistry) applicationContext.getBean(MessageBusParser.MESSAGE_BUS_BEAN_NAME);

		MessageChannel returnChannel = new SimpleChannel(); 

		String tmpReplyChannel = "aTemp" + nextId++;
		channelRegistry.registerChannel(tmpReplyChannel, returnChannel);

		GenericMessage requestMessage = new GenericMessage<ATransaction>(aTransaction);
				
		requestMessage.getHeader().setReturnAddress(outputChannel);

		requests.send(requestMessage);

		Message replyMessage = returnChannel.receive(5000);

		if (replyMessage == null) {
			saveMessage(request, "processing timed out");
		} else {
			ATransaction responseMessage = (ATransaction) replyMessage.getPayload();
			
			System.out.println(responseMessage);
		}
		
		channelRegistry.unregisterChannel(tmpReplyChannel);
	}

To recieve the correlated reply message, I created a temporary message channel and register it with the MessageBus, is that the best practice to implement Request/Reply style interaction in Spring Integration or Is there other alternative method?
