json - 使用 spray-json 将嵌套案例类转换为 JSON

Question

如果我有嵌套的案例类，如何使用 spray-json 将它们转换为 JSON？

例如我的结构看起来像：

case class MyObj1(name: String, myObject2: MyObject2)
case class MyObj2(myObjec3s: Seq[MyObj3])
case class MyObj3(name1: String, name2: String)

The json would look something like:
{
  "name": "",
  "myObject2": [ { "name1": "", "name2": "" }, { "name1": "", "name2": "" }, .... ]
}
