我应该如何在Scala中指定类似JSON的非结构化数据的类型？

import spray.json._

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

object PersonProtocol extends DefaultJsonProtocol {
  implicit val personFormat = jsonFormat2(Person)
}

import PersonProtocol._

val jsonString = """{"name": "Alice", "age": 30}"""
val json = jsonString.parseJson
val person = json.convertTo[Person]

import spray.json._

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

object PersonProtocol extends DefaultJsonProtocol {
  implicit val personFormat = jsonFormat2(Person)
}

import PersonProtocol._

val jsonString = """[{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}]"""
val json = jsonString.parseJson
val persons = json.convertTo[List[Person]]
