在GlobalSettings onStart（Play Framework）中访问application.conf

Question

I am using Java / Play Framework 2.1.0.

I have found other questions asking how to access application.conf, and I tried two methods:

Play.application().configuration().getString("my.thing");

and

ConfigFactory.load().getString("my.thing");

In both cases I dont get anything back. I am trying to do this in onStart of my Global class. Maybe onStart happens before configuration is loaded?

How can I access values in application.conf from within onStart? (Or, to be more precise, how do I access values in myapp.conf which is included in application.conf)

Answer 1

Can you verify that your onStart is getting called at all?

The configuration values are loaded and accessible at that point. In fact, you are getting the play.Application instance passed as an argument, so you can just do this:

  public void onStart(Application app)
  {
    super.onStart(app);
    String value = app.configuration().getString("my.thing");
    // do something with value
  }
