Does Spring Cloud Stream project needs web server (Tomcat) or not?

Question

I'm using Spring Cloud Stream to write messaging-driven microservices.

• Project A: Producer (Spring Cloud Stream, integrated tomcat and its port: 8080)
• Project B: Consumer (Spring Cloud Stream, integrated tomcat and its port: 8081)
• Message Broker: RabbitMQ (amqp port: 5672)

My question is: For project A & B, do them need integrated web server/port (Tomcat) or not? Or just a common java application would be fine?

Answer 1

If you don't want to access Boot's web support (actuator etc), you can disable the web using the application builder.

Simply add

.web(false)

before the run().

Alternatively, just set remote.port=0 and a random port will be selected for each.
