adding header to GenericMessage

[nadia.tishutina]

Hi again, I am trying to send a message through the channel with a String payload and some custom header, like this:

DirectChannel channel = (DirectChannel) context
				.getBean("senderChannel");
		
		Map<String, Object> m = new HashMap<String, Object>();
		m.put("foo", "test");
		GenericMessage<String> msg = new GenericMessage<String>("<xml>NST description</xml>", m);
		
		channel.send(msg);
		System.out.println("sent message: " + msg.toString());

When I run the code, I see that the header is added because I see this in the log:

sent message: [Payload=<xml>NST description</xml>][Headers={timestamp=1346981165529, id=6f965773-48a9-4bc3-970d-352de19bbb06, foo=test}]

However, when I go to RabbitMQ console and look at the message, my foo header does not show up ( I can see the payload though). Any advice?
thank you

Well, you need to show us the configuration for your application context but, essentially, you need to tell the outbound endpoint to map your custom header (foo).

See attribute mapped-request-headers.
