Scala将多层json转换为多层地图

import play.api.libs.json._

// 定义多层JSON字符串
val jsonStr = """
{
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "country": "USA"
  }
}
"""

// 解析JSON字符串为JsValue对象
val json = Json.parse(jsonStr)

// 将JsValue对象转换为多层地图
val map = json.as[Map[String, Any]]

// 访问地图中的数据
val name = map("name").asInstanceOf[String]
val age = map("age").asInstanceOf[Int]
val address = map("address").asInstanceOf[Map[String, Any]]
val street = address("street").asInstanceOf[String]
val city = address("city").asInstanceOf[String]
val country = address("country").asInstanceOf[String]

// 打印结果
println(s"Name: $name")
println(s"Age: $age")
println(s"Street: $street")
println(s"City: $city")
println(s"Country: $country")
