Using wildcard character '*' to match anything in application.conf Play application

Question

Is there a way to specify Wildcard character like '*' to match anything. For Eg: I want to specify the configuration like this in application.conf.

application.*.config = value1

In the application I want this "value1" to get picked up for any of the below keys I specify.

application.test.config  
application.prod.config  
application.staging.config

How can I achieve this?

No there is not, you have two solutions

1. You can use application modes ( Dev , Prod or Test ) ie like this:

    application { Dev.value = "My value for DEV" Prod.value = "My value for PROD" Test.value = "My value for TEST" } // controller String myValue = Play.application().configuration().getString("application." + Play.application().getWrappedApplication().mode().toString() + ".config"); 

2. You can create 3 alternative configs for your states and override ONE param ie application.config , of course you will need to specify required alt. config file while running in given mode.
