Camel provides a nice capability in the dynamic router.  However it inherits a weakness from routingSlip in that state must be kept inside the method call.  Is there a nice way to have a one time routing slip without saving state?  currently you are forced to do something like this

:

public class MessageDistributionDynamicRouter

{

    //must keep state to stop the routing slip

    private volatile Object lastBody = null ;

    public String destinationQueue(@Header("sessionId") final String sessionId, @Body final Object body)

    {

        if (lastBody == body)

        {

            return null;

        }

        lastBody = body;

        //route to destination outbound queue

        return QueueName.getOutboundQueueName(sessionId) ;

    }

}
