How to configure port for a Spring Boot application

Question

How do I configure the TCP/IP port listened on by a Spring Boot application, so it does not use the default port of 8080.

Answer 1

Indeed, the easiest way is to set the server.port property.

If you are using STS as IDE, from version 3.6.7 you actually have Spring Properties Editor for opening the properties file.

This editor provides autocomplete for all Spring Boot properties. If you write port and hit CTRL + SPACE, server.port will be the first option.
