Since no 'subject' is specified by default in hello world, and the exchange type is a 'topic' exchange that supports wildcarding, the key used for the binding is '#' which matches anything."
Does that mean if a listener is listening to a TopicExchange instead of a queue then it is bound to all the queues of the exchange (i.e the listener will get whatever goes through the exchange to other queues) ?
