PublishedMessageBuilder

Name of exchange on which the message is published. Can be empty.

When matching queue has at least one or more consumers and immediate is set to true, message is delivered to them immediately. When matching queue has zero active consumers and immediate is set to true, message is returned to publisher. When matching queue has zero active consumers and immediate is set to false, message will be delivered to the queue.

When a published message cannot be routed to any queue and mandatory is true, the message will be returned to publisher. Returned message must be handled with returnListener or returnConsumer.
