scala的fastjson

import com.alibaba.fastjson.{JSON, JSONObject}

val str="{"boxId":"001","allContent":[{"fruitName":"apple","weight":"1"},{"fruitName":"orange","weight":"2"},{"fruitName":"strawberry","weight":"3"}]}"
val jsonobj=JSON.parseObject(str)
val result1=jsonobj.getString("allContent")
println(result1)

val jsonArrGet=jsonobj.getJSONArray("allContent")
println(jsonArrGet)

//遍历JSONArray中的所有数据
//getJSONObject + 数组下标
for(i <- 0 until jsonArrGet.toArray.length){
  val nObject=jsonArrGet.getJSONObject(i)
  println("nObject: "+nObject)

  val nStr=nObject.getString("fruitName")
  println("nStr: "+nStr)
}



//遍历JSONArray中的所有数据
//JSONArray转化为集合
import scala.collection.JavaConversions._
val list = jsonArrGet.iterator().toList
val listOBJ = list.map(m=> JSON.parseObject(m.toString)) //或者 m.asInstanceOf[JSONObject]
for (ele <- listOBJ){
  println("ele: "+ele)
  val str=ele.getString("fruitName")
  println("ele.getStr: "+str)
}
