Play provides Configuration object to access configuration keys from the application.conf keys.

Here is how you can get access to play Configuration object.

class HomeController @Inject() (configuration: play.api.Configuration) extends Controller {
  def foo = Action {

    val appSecretString = configuration.underlying.getString("application.secret")

    //do something with app secret
    Ok(appSecretString) //app secret should not be exposed, just trying to show it on browser, but do not do this in production
  }
}
