[rabbitmq-discuss] How to determine originator of a message?

Tue Aug 14 13:33:05 BST 2012

You can use props to tag msgs anyway you like..

 AMQP.BasicProperties props = new AMQP.BasicProperties();

 BasicProperties.Builder prop = props.builder();
 prop.messageId(msgID);
 prop.deliveryMode(2);
 prop.userId(UserID);

No, not unless the the publisher annotated the message in some way, but
publishers are under no obligation to disclose their identity. The
broker will validate the user-id property in messages, if the publisher
chooses to disclose its identity using that property. See
