Custom configuration files - Play! Framework 2.0

Question

I have a question about loading properties from custom configuration files. I have tried two different approaches to loading my oauth.properties file but I can't get either to work so I'm hoping someone here can help me.

The first approach I tried was to add the file to the conf directory and reference it thusly:

String oauthPropertiesFile = ClassLoader.getSystemResource("oauth.properties").getFile();

But that just returned NULL .

The second approach I tries was to add:

@include.oauthProperties = oauth.properties

to the application.conf file and then reference it in my controller like:

String clientId = oauthProperties.clientId;

However this doesn't compile.

Can anyone shed some light on what I'm doing wrong here?

Answer 1

What worked for me with a file in /conf :

import com.typesafe.config.ConfigFactory

val myConfig = ConfigFactory.load("myfile.properties").getConfig("my.config.prefix")

Answer 2

I'm not sure if conf is part of the classpath. So I would try /conf/oauth.properties or put the file into the classpath. Furthermore you should use Play.application.classloader() instead of Classloader.

About the include: I still think you need to call Play.application().configuration().get("clientID");

To analyze the situation you can start the app with -Dconfig.trace=loads and analyse the configuration with Play.application().configuration().root().render() .

Hope this give you enough hints so that you can solve your problem.

在一般情况下，要使用Play 2.2从“ / conf”目录中获取任何文件，可以按照以下步骤进行操作（请注意，“ / conf”在类路径上，因此您不应包括它）。

Play.application().classloader().getResource("any_file");

如果要使用scala.io.Source还可以执行以下操作

Source.fromFile(Play.getFile("path-in-your-play-project"))
