When the exception is thrown, it is wrapped together with the requestMessage to the MessagingException. Your own business exception is in the cause and you can get access to the requestMessage from the MessagingException.failedMessage property.

So, it looks like you have everything you need for your use-case. Only the problem that before sending to the error-exchange you really should have some <transformer> in the error flow to properly convert that MessagingException to the proper message to send to the AMQP.
