amqp - RabbitMQ - Regex Implementation Topic Exchange -

suppose, if have binding key "a.b.*" can use routing keys a.b.1, a.b.2, a.b.3 , a.b.4 , on.

i want queue accept messages these routing keys except routing key "a.b.3". how can implemented?

or there way can use regex binding key instead of wildcard characters "*" , "#".

no; there's no regex, 2 wildcards.

you can use multiple bindings though - have explicitly bind queue a.b.1, a.b.3, a.b.4, then, might use direct exchange.
