如何使用Scala反射获取声明类/特征？

import scala.reflect.runtime.{universe => ru}

def getClassType(className: String): ru.Type = {
  val mirror = ru.runtimeMirror(getClass.getClassLoader)
  val classSymbol = mirror.staticClass(className)
  classSymbol.selfType
}

val className = "com.example.MyClass"
val classType = getClassType(className)
val declarations = classType.declarations

declarations.foreach { declaration =>
  // 获取声明类/特征的名称
  val name = declaration.name.toString
  // 获取声明类/特征的类型
  val declarationType = declaration.typeSignature
  // 进行相应的操作，例如打印信息
  println(s"Declaration: $name, Type: $declarationType")
}
