Location of `application.properties

The exposed settings for your web-server, can be found in src/main/resources/application.properties.

If you build your own .war-file, you can change the values before building to the ones you need. This will ensure, that the final file will use these properties, if no external application.properties-file exists.

If you already have a .war-file, but want to change the properties in the file without rebuilding it, you can add an external application.properties-file. To do this, just add a config folder in the directory, where your .war-file is stored. Inside of that config-folder, add a application.properties-file and fill it with the properties you need.
