Custom configuration files - Play! Framework 2.0
提问by travega
I have a question about loading properties from custom configuration files. I have tried
two different approaches to loading my oauth.propertiesfile but I can't
get either to work so I'm hoping someone here can help me.
我有一个关于从自定义配置文件加载属性的问题。我尝试了两种不同的方法来加载我的oauth.properties文件，但我无法使用任何一种方法，所以我希望这里有人可以帮助我。
The first approach I tried was to add the file to the conf directory and reference it thusly:
我尝试的第一种方法是将文件添加到 conf 目录并以此引用它：
String oauthPropertiesFile = ClassLoader.getSystemResource("oauth.properties").getFile();
But that just returned NULL.
但那只是回来了NULL。
The second approach I tries was to add:
我尝试的第二种方法是添加：
@include.oauthProperties = oauth.properties
to the application.conffile and then reference it in
my controller like:
到application.conf文件，然后在我的控制器中引用它，如：
String clientId = oauthProperties.clientId;
However this doesn't compile.
但是，这不会编译。
Can anyone shed some light on what I'm doing wrong here?
任何人都可以阐明我在这里做错了什么吗？

What worked for me with a file in /conf:
什么对我有用/conf：
import com.typesafe.config.ConfigFactory
val myConfig = ConfigFactory.load("myfile.properties").getConfig("my.config.prefix")

I'm not sure if conf is part of the classpath. So I would try /conf/oauth.propertiesor put the file into the classpath. Furthermore you should use Play.application.classloader()instead of Classloader.
我不确定 conf 是否是类路径的一部分。所以我会尝试/conf/oauth.properties或将文件放入类路径。此外，您应该使用Play.application.classloader()而不是 Classloader。
About the include: I still think you need to call Play.application().configuration().get("clientID");
关于包括：我还是觉得你需要打电话 Play.application().configuration().get("clientID");
To analyze the situation you can start the app with -Dconfig.trace=loadsand analyse the configuration with Play.application().configuration().root().render().
要分析情况，您可以使用 启动应用程序-Dconfig.trace=loads并使用 分析配置Play.application().configuration().root().render()。
Hope this give you enough hints so that you can solve your problem.
希望这能给您足够的提示，以便您可以解决您的问题。

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).
在一般情况下，要从“/conf”目录中获取任何文件，使用 Play 2.2 可以按如下方式完成（请注意，“/conf”位于类路径中，因此不应包含它）。
Play.application().classloader().getResource("any_file");

If you want to use scala.io.Sourceyou can also do something like
如果你想使用scala.io.Source你也可以做类似的事情
Source.fromFile(Play.getFile("path-in-your-play-project"))
