Question

假设：

的src /测试/阶/净/ Main.scala

package net

import com.typesafe.config.ConfigFactory

object Main extends App {
    override def main(args: Array[String]) {
        val bar   = ConfigFactory.load().getString("app.bar")
        val bippy = ConfigFactory.load().getString("app.bippy")
        println(s"bar: $bar | bippy : $bippy")
    }
}

的src /测试/资源/ application.conf

app {
    bar = ${?BAR}
    bippy = ${?BIPPY}
}

我尝试在BAR中设置BIPPY和sbt个环境变量：

>set envVars := Map("BAR" -> "bar!", "BIPPY" -> "bippy!")

然后，我在测试模式下打开了REPL：

>test:console

scala> import net.Main
import net.Main

scala> Main.main(Array())
com.typesafe.config.ConfigException$Missing: No configuration setting 
    found for key 'app.bar'

如何为REPL设置这些属性？

使用-Dconfig.file系统属性

传递配置文件

[localhost]$ sbt -Dconfig.file=src/test/resources/application.conf

设置要在REPL中访问的配置属性
