I started a new Spring boot project, I want to change the port number and I read that I have to modify the /resource/application.properties
to do so.
I cannot locate this file however, did I miss something? Do I need to install a boot starter? I don't want to set this using the spring CLI.
Should I create this file manually? If so, I think I'll have to mark this file as the properties file somewhere in the code. Where would that be?
Thanks a lot!

You will need to add the application.properties
file in your classpath.
If you are using Maven or Gradle, you can just put the file under src/main/resources
.
If you are not using Maven or any other build tools, put that under your src folder and you should be fine.
Then you can just add an entry server.port = xxxx
in the properties file.
In the your first journey in spring boot project I recommend you to start with Spring Starter Try this link here.
It will auto generate the project structure for you like this.application.perperties it will be under /resources.
application.properties important change,
server.port = Your PORT(XXXX) by default=8080
server.servlet.context-path=/api (SpringBoot version 2.x.)
server.contextPath-path=/api (SpringBoot version < 2.x.)
Any way you can use application.yml in case you don't want to make redundancy properties setting.
Example
application.yml
server:
port: 8080
contextPath: /api
application.properties
server.port = 8080
server.contextPath = /api
You can also create the application.properties file manually.
SpringApplication will load properties from application.properties files in the following locations and add them to the Spring Environment:
The list is ordered by precedence (properties defined in locations higher in the list override those defined in lower locations). (From the Spring boot features external configuration doc page)
So just go ahead and create it
Spring Boot will automatically find and load application.properties and application.yaml files from the following locations when your application starts:
The list is ordered by precedence (with values from lower items overriding earlier ones).
