Scala:如何获取case类的属性名称

import scala.reflect.runtime.universe._

case class Person(name: String, age: Int)

object Main extends App {
  val mirror = runtimeMirror(getClass.getClassLoader)
  val classSymbol = mirror.staticClass("Person")
  val classMirror = mirror.reflectClass(classSymbol)
  val constructor = classSymbol.primaryConstructor.asMethod
  val constructorMirror = classMirror.reflectConstructor(constructor)

  val instance = constructorMirror("John", 30).asInstanceOf[Person]

  val fields = typeOf[Person].members.collect {
    case m: MethodSymbol if m.isCaseAccessor => m
  }

  val propertyNames = fields.map(_.name.toString)
  println(propertyNames)
}
