使用列表从scala对象创建Json

libraryDependencies += "com.typesafe.play" %% "play-json" % "2.9.2"

import play.api.libs.json._

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

val personList = List(
  Person("Alice", 25),
  Person("Bob", 30),
  Person("Charlie", 35)
)

implicit val personWrites: Writes[Person] = Json.writes[Person]

val json = Json.toJson(personList)

println(json)

[
  {
    "name": "Alice",
    "age": 25
  },
  {
    "name": "Bob",
    "age": 30
  },
  {
    "name": "Charlie",
    "age": 35
  }
]
