How do I choose the URL for my Spring Boot webapp?

I am using Spring Boot to create a web app, and I am not sure how to change the URL from localhost:8080 to something like localhost:8080/myWebApp.

I have a seen a lot of resources online referencing an application.properties file and adding that to the classpath. But, I'm not sure exactly where to put that.

Questions

In my src/main/resources?
How would I assign the URL within the file?

Solution

You need to set the property server.contextPath to /myWebApp.

Check out this part of the documentation

The easiest way to set that property would be in the properties file you are using (most likely application.properties) but Spring Boot provides a whole lot of different way to set properties. Check out this part of the documentation

EDIT

As has been mentioned by @AbdullahKhan, as of Spring Boot 2.x the property has been deprecated and should be replaced with server.servlet.contextPath as has been correctly mentioned in this answer.
