最佳答案
在 ApiSpec
类中,您有一些在实例化时可能为 null 的变量:
val cfg = ConfigFactory.load("http.conf")
val testToken = cfg.getString("token.normal")
val testAdvancedToken = cfg.getString("token.advanced")
implicit val http = new SprayHttp {
val config = new SprayHttpConfig {
val system = ActorSystem("test")
val gzipEnable = true
}
val context = config.system.dispatcher
}
您可以将这些值变成惰性值以避免这种情况:
lazy val cfg = ConfigFactory.load("http.conf")
lazy val testToken = cfg.getString("token.normal")
lazy val testAdvancedToken = cfg.getString("token.advanced")
implicit lazy val http = new SprayHttp {
lazy val config = new SprayHttpConfig {
val system = ActorSystem("test")
val gzipEnable = true
}
val context = config.system.dispatcher
}
