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

Answer 1

Starting from version 2.5 please use play.Application class which should be injected and then application.config().getString("your.property.here")

Answer 2

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 3

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");

Answer 4

In Play 1.2.x

import play.Play;
...


String version  = Play.configuration.getProperty("application.version.number", "1.1.1");

where the second parameter is the default value

Answer 5

Import this

import com.typesafe.config.Config;

and write the below lines

private Config config;
this.config = ConfigProvider.config();
String value = this.config.getString("fieldFromConfigFile");

Answer 6

In the play java is:

import play.Play;
...
Play.application().configuration().getString("key")
