I'm having trouble to identify a way to delay message level in SpringAMQP.
I call a Webservice if the service is not available or if it throws some exception I store all the requests into RabbitMQ queue and i keep retry the service call until it executes successfully. If the service keeps throwing an error or its not available the rabbitMQ listener keeps looping.( Meaning Listener retrieves the message and make service call if any error it re-queue the message)

I restricted the looping until X hours using MessagePostProcessor however i wanted to enable delay on message level and every time it tries to access the service. For example 1st try 3000ms delay and second time 6000ms so on until i try x number of time.

It would be great if you provide a few examples.

Could you please provide me some idea on this?
