java - Scala 包对象getClass

Question

我想为 Scala 包对象获取 java.lang.Class:

应用程序/package.scala:

package object app {
}

应用/Main.scala:

打包应用

object Main extends App {
  val _ = app.getClass
}

编译失败:

object getClass is not a member of package app Note that app extends Any, not AnyRef. Such types can participate in value classes, but instances cannot appear in singleton types or in reference comparisons.

Answer 1

您可以在应用程序返回类中定义方法:

package object app {
  def cls = getClass
}
