将json数组转换为scala列表

import scala.collection.mutable.ListBuffer
import scala.util.parsing.json.JSON

val jsonArrayString = "[{\"name\":\"Alice\",\"age\":25},{\"name\":\"Bob\",\"age\":30}]"

val jsonArray = JSON.parseFull(jsonArrayString)

val scalaList = jsonArray match {
  case Some(list: List[Map[String, Any]]) =>
    val buffer = ListBuffer.empty[Map[String, Any]]
    buffer ++= list
    buffer.toList
  case _ => List.empty[Map[String, Any]]
}

val firstElement = scalaList.headOption.getOrElse(Map.empty[String, Any])
val name = firstElement.getOrElse("name", "").asInstanceOf[String]
val age = firstElement.getOrElse("age", 0).asInstanceOf[Int]
