Scala日期和字符串互转

import java.util.Date
import java.text.SimpleDateFormat
case class myclass(id :String,actionDate:java.util.Date)
val TIME_FORMAT= new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")
val actionTime = TIME_FORMAT.parse("2010-10-10 10:10:10")

val actionTimeString = TIME_FORMAT.format(actionTime)
val mTime = actionTime.getTime()
