Where is the application.properties file in a Spring Boot project?

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?

Solution

  • 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.
