Using Existing Queues/Exchanges

By default, the binder will automatically provision a topic exchange with the name being derived from the value of the destination binding property <prefix><destination>. The destination defaults to the binding name, if not provided. When binding a consumer, a queue will automatically be provisioned with the name <prefix><destination>.<group> (if a group binding property is specified), or an anonymous, auto-delete queue when there is no group. The queue will be bound to the exchange with the "match-all" wildcard routing key (#) for a non-partitioned binding or <destination>-<instanceIndex> for a partitioned binding. The prefix is an empty String by default. If an output binding is specified with requiredGroups, a queue/binding will be provisioned for each group.

There are a number of rabbit-specific binding properties that allow you to modify this default behavior.

If you have an existing exchange/queue that you wish to use, you can completely disable automatic provisioning as follows, assuming the exchange is named myExchange and the queue is named myQueue:

If you want the binder to provision the queue/exchange, but you want to do it using something other than the defaults discussed here, use the following properties. Refer to the property documentation above for more information.

There are similar properties used when declaring a dead-letter exchange/queue, when autoBindDlq is true.
