Play2 JSON support for Byte

Question

How can I handle Byte in Json Scala API, for example parsing:

json.as[Byte]

Do I have to write own Reads?

implicit val ByteRead = new Reads[Byte] {
   override def reads(json: JsValue): JsResult[Byte] = JsSuccess(json.as[Int].toByte)
}

Answer 1

Yupp，您必须使用自己的实现，因为没有内置的Reads [Byte]。
