How to Publish / Subscribe MQTT messaging (mosquitto) dynamically?

[lcy-1024]

This example is not dynamically:

I found the same question in stackoverflow:

In order to publish to different topics from the same channel, you can use the MqttMessage.of(topic, ...) signature to create your message with a specific topic. Then you can use emitter or outgoing channel to send that message to the broker.

For consuming events from multiple topics, the channel configuration topic supports + and # wildcards. If different topics you'd like to consume don't fit the wildcards, you need to create multiple channels.

Thank you for your reply.
Is there any way to consuming events without channel mode, just like publish topics we can use emitter instead of channel mode.

Is there a way to run without using the following configuration:
