java - Play Framework 2.3.8 Java - 使用特定模式覆盖默认配置加载

Question

我想使用 Java 在 Play Framework 2.3.8 中实现模式特定的配置加载。我知道这在 Scala 中是可以实现的:

import java.io.File
import play.api._
import com.typesafe.config.ConfigFactory

object Global extends GlobalSettings {
  override def onLoadConfig(config: Configuration, path: File, classloader: ClassLoader, mode: Mode.Mode): Configuration = {
    val modeSpecificConfig = config ++ Configuration(ConfigFactory.load(s"application.${mode.toString.toLowerCase}.conf"))
    super.onLoadConfig(modeSpecificConfig, path, classloader, mode)
  }
}

目前我设法在 java 中实现相同的功能，但无法从 com.typesafe.config.Config 强制转换 typesafe-s ConfigFactory.load(modeSpecificConfigFile) 返回对象到play.Configuration:

 @Override
    public Configuration onLoadConfig(Configuration configuration, File file, ClassLoader classLoader, Mode mode) {
        String modeSpecificConfigFile = "application." + mode.toString().toLowerCase() + ".conf";
        Logger.debug("Loading mode specific configuration from: " + modeSpecificConfigFile);
        Configuration modeSpecificConfig = ConfigFactory.load(modeSpecificConfigFile);
        return super.onLoadConfig(modeSpecificConfig , file, classLoader);
    }

谢谢!

将其包装到play.Configuration中:

Configuration modeSpecificConfig = new play.Configuration(ConfigFactory.load(modeSpecificConfigFile));
