Spring AMQP supports the RabbitMQ Delayed Message Exchange Plugin.
For inbound messages, the x-delay header is mapped to the AmqpHeaders.RECEIVED_DELAY header.
Setting the AMQPHeaders.DELAY header causes the corresponding x-delay header to be set in outbound messages.
You can also specify the delay and delayExpression properties on outbound endpoints (delay-expression when using XML configuration).
These properties take precedence over the AmqpHeaders.DELAY header.
