问题
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?
回答1:
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.

What worked for me with a file in /conf:
import com.typesafe.config.ConfigFactory
val myConfig = ConfigFactory.load("myfile.properties").getConfig("my.config.prefix")
回答3:
In a generic case, to fetch any File from the "/conf" directory, using Play 2.2 it can be done as follows (note that "/conf" is on the classpath, so you should not include it).
Play.application().classloader().getResource("any_file");

If you want to use scala.io.Source you can also do something like
Source.fromFile(Play.getFile("path-in-your-play-project"))
