Accessing the application.conf properties from java class with Play! 2.0

Question

I want to add an object to the Global scope, and in order to construct it I need to pass it a path to a file. I don't want to hard code the file path in the source, and so I want to get that path from the application.conf.

The problem is that I don't know how to access these properties from the java class. I tried this:

Configuration.root().getString("file.path") 

But it ends with a NullPointerException.

Am I wrong in assuming that there's a global Configuration instance that I can use? Thanks.

Answer 1

Try Play.application().configuration().getString("your.key")

As noted in the comment (nico_ekito), please use play.Play and not play.api.Play. play.api.Play is for scala controllers (see comment by Marcus biesior Biesioroff)

Additionally, play uses https://github.com/typesafehub/config under the hood so it can also provide some insights.

Answer 2

Even if it seems simple, here is the scala way to get properties from configuration file :

Play 2.0 and 2.1 :

import play.api.Play.current ... Play.application.configuration.getString("your.key") 

Play 2.2 and +

import play.api.Play.current ... current.configuration.getString("your.key") 

Using Typesafe config

import com.typesafe.config.ConfigFactory ... ConfigFactory.load().getString("your.key");
