RabbitMQ Topic format - sub-topic under main topic - rabbitmq

Question

When I am trying to push to topic in this format /topic/pushing/{organizationId} I am getting an error
messagingTemplate.convertAndSend("/topic/pushing/" + obj.getCustomerid(), obj);
The error:
15:06:48.901 [reactor-tcp-io-1] ERROR
o.s.m.s.s.StompBrokerRelayMessageHandler - Received ERROR
{message=[Invalid destination], content-type=[text/plain],
version=[1.0,1.1,1.2], content-length=[53]} session=system
text/plain payload='/pushing/2963_ent' is not a valid topic
destination
However when I change it to this format /topic/pushing.{organizationId}, replacing the slash with dot, it's working fine:
messagingTemplate.convertAndSend("/topic/pushing." + obj.getCustomerid(), obj);
Any idea how I can keep the slash / and have sub-topics under the main topic.

AMQP 0.9.1 specification has this to say about topic exchanges:
The topic exchange type works as follows:
1. A message queue binds to the exchange using a routing pattern, P.
2. A publisher sends the exchange a message with the routing key R.
3. The message is passed to the message queue if R matches P. The routing key used for a topic exchange MUST consist of zero or more
words delimited by dots. Each word may contain the letters A-Z and a-z
and digits 0-9.
The routing pattern follows the same rules as the routing key with the
addition that * matches a single word, and # matches zero or more
words. Thus the routing pattern *.stock.# matches the routing keys
usd.stock and eur.stock.db but not stock.nasdaq.
So "/" are not authorized in the routing key, and delimiter used is a dot.
