【总结】使用Scala实现Json与Case Class相互转换

import 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))
}
