Outbound User ID
Spring AMQP version 1.6 introduced a mechanism to allow the specification of a default user ID for outbound messages.
It has always been possible to set the AmqpHeaders.USER_ID
header, which now takes precedence over the default.
This might be useful to message recipients.
For inbound messages, if the message publisher sets the property, it is made available in the AmqpHeaders.RECEIVED_USER_ID
header.
Note that RabbitMQ validates that the user ID is the actual user ID for the connection or that the connection allows impersonation.
To configure a default user ID for outbound messages, configure it on a RabbitTemplate
and configure the outbound adapter or gateway to use that template.
Similarly, to set the user ID property on replies, inject an appropriately configured template into the inbound gateway.
See the Spring AMQP documentation for more information.
