spark读取csv文件用类进行封装最后转成json写出到本地

package scala

import com.google.gson.{Gson, JsonObject, JsonParser}
import org.apache.spark.sql.{Row, SaveMode, SparkSession}

object CsvParse {

  case class Data(callerip: String,callere164: String, calleee164: String, starttime: String,
                  stoptime: String, holdtime: String, feetime: String, fee: String, 
                  enddirection: String, endreason: String)

  def main(args: Array[String]): Unit = {
    val spark = SparkSession.builder().master("local[*]").appName("SparkCsv").getOrCreate();
    import spark.implicits._
    val df = spark.read.option("header", "true").csv("D:\\tmp\\home2").select("callerip", "callere164", "calleee164", "starttime", "stoptime",
      "holdtime", "feetime", "fee", "enddirection", "endr
