title: Where is the application.properties file in a Spring Boot project?
body: <p>I started a new Spring boot project, I want to change the port number and I read that I have to modify the <code>/resource/application.properties</code> to do so. </p>
  
  <p>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. </p>
  
  <p>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?</p>
  
  <p>Thanks a lot!</p>
