json case classimport org.json4s.native.Serialization.{read, write}
object Json2CaseClass extends App {
implicit val formats = org.json4s.DefaultFormats
case class Class(_name:String, students: List[Student])
case class Student(sid:String, _name:String)
val s = "{\"_name\":\"Class1\",\"students\":[{\"sid\":\"1\",\"_name\":\"小明\"},{\"sid\":\"1\",\"_name\":\"小王\"}]}"
val clazz:Class = read[Class](s)
println(clazz)
println(write(clazz))
}
