如何在scala play上使用给定的结构读取json？

Question

I have a json list structure like this, how can we read this structure and convert in a list in scala, play framwork.

{
"0":{
    "name":"Foo",
    "age":10
  },
"12":{
    "name":"Bar",
     "age":10
  }
  .
  .
  .
}

If, there were json structure like below, I could have done it easily, but since I am not that versed in parsing Json and actually new to scala too, I couldn't understand how to work with Json strucutures that have key as "0","12" like in the first example. I had been using Jerkson wrapper for Jackson for generating/parsing json/case-class.

{
{"name":"Foo","age":10},
{"name":"Bar",age:11}
}

Update:

I actually succeeded in parsing the json structure, in addition to Ryans answer,

import play.api.libs.json._

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

object Doodad {
  implicit val fmt = Json.format[Doodad]

def parserFuntion = {
var myJsValue: JsValue = Json.parse(jsonString)// added line in the ans
    var requiredMap = myJsValue.validate[Map[String, Doodad]]
}
    }

But now I have a new questions, the json structure I working with seems to be a bit irregular for eg:

{
"0":{
    "name":"Foo",
    "age":10
  },
"12":{
    "name":"Bar",
    "age":10
  },
"13":{
    "name":"Foobar"
    "age":20,
    "meta":{
             "desc":"Irregular Json",
             "img":"Some Link"
           }
  },
      .
      .
      .
    }

Chances are some of the json list elements might have that extra "meta" key->value pair, and some might not. So, how can we deal with such situations. Any ideas??

Answer 1

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

object Doodad {
  implicit val fmt = Json.format[Doodad]
}

myJsValue.validate[Map[String, Doodad]] // JsResult[Map[String, Doodad]]
