1.scala java map转 scala map

import scala.collection.JavaConverters._
var questObj:scala.collection.mutable.Map[String,Any]=
mapAsScalaMapConverter(oneJavaMap).asScala.map(kv=>{((kv._1.toString)->kv._1)})

另外记录一下 java list转dataset/dataframe

QuestInfo是一个javabean,questList是一个QuestInfo的list

val dataset:Dataset[Row]=spark.createDataFrame(questList,classOf[QuestInfo])
