    Description

      As per VMware Support Request 13319275205, I had requested a way to enricher headers in a similar way that you can use the <enricher> to enrich payloads. The solution in combination with a jdbc:outbound-gateway was outlined as follows:

      <int:header-enricher input-channel="publishingChannel" output-channel="outputConsole">
	<int:header name="status" expression="@statusFlow.exchange(#root).payload['STATUS']" />
</int:header-enricher>
		 		 
<int:gateway id="statusFlow" default-request-channel="getStatusForDeal" />
		 		 
<int:chain input-channel="getStatusForDeal">
	<int:transformer expression="payload.dealId" />
	<jdbc:outbound-gateway query="select status from trade_details where dealId = :payload"
		data-source="dataSource" />
</int:chain>

      This solution isn't immediately obvious so I was wondering whether this could be documented in some way (the Github Wiki has been requested) or ideally we can one day see a header enricher based on the payload enricher.
