问题 From spring boot tutorial: https://spring.io/guides/gs/messaging-rabbitmq/ They give an example of creating 1 queue and 1 queue only, but, what if I want to be able to create more then 1 queue? how would it be possible?

I am confused about the DirectMessageListenerContainer.setConsumersPerQueue method. The default value is 1 looking at the source code. Under what conditions would one need to increase it to greater than 1? If left to default value of 1, is the

问题 I have configured spring cloud config to read properties from a git repository.With the current implementation if there is a change in the configuration, if post to /refresh on my client I am able to see the updated properties. Now, I would like to use the spring-cloud-bus-monitor to detect changes in my git repo and automatically refresh the properties in my client endpoints. Even after adding spring-cloud-config-monitor in the dependencies - the /monitor endpoint is not enabled, and
