Tomcat server logs not showing in spring boot application

Question

I have a spring boot application where I have configured a listener consuming messages in a queue. I also have a controller which is used for healthcheck purposes. When the service starts, I get the following logs. But I don't see any logs on the Tomcat server atarting and the port it is running on.

I have another similar service and following are the logs shown

2022-07-15 15:43:57.812  INFO 227112 --- [           main] o.s.b.w.embedded.tomcat.TomcatWebServer  : Tomcat initialized with port(s): 8000 (http)

I can see the tomcat server logs in the other application even though all the dependencies are pretty much the same.

I can also see the tomcat jars present in the external libraries: tomcat-embed-core-9.0.16.jar , tomcat-embed-el-9.0.16.jar , tomcat-embed-websocket-9.0.16.jar .

The service is consuming the message and processing it but I'm struggling to deploy it on a server.

Edit:

Found the issue, one line in the application.properties file was causing this.

spring.main.web-application-type=none

Removed this and I was able to see the port in which tomcat has started and was able to hit my controller correctly.

Try this!

Define the following in application.yml or application.properties

logging:
 level:
   org.apache:
    DEBUG

Alternatively, before starting your application, you can also check Enable debug output in your Run configurations !
