this project uses tomcat server , runs on port 8080 default. can me understand picks configuration , how change port on tomcat runs.

my preliminary analysis tells me there configuration done in spring.boot plugin need override in pom. can me in overriding tomcat default port , run on other port.

27.3.4 customizing embedded servlet containers says (in part)

common servlet container settings can configured using spring environment properties. define properties in application.properties file.

common server settings include:

• network settings: listen port incoming http requests (server.port), interface address bind server.address, etc.

so, create src/main/resources/application.properties , add

 server.port=${port:8081} 

(or whatever port want).
