scala时间和时间戳互转

时间转换为时间戳：

import java.text.SimpleDateFormat

object test {

  def main(args: Array[String]): Unit = {

    val tm = "2017-08-01 16:44:32"
    val a = tranTimeToLong(tm)
    println(a)
  }

  def tranTimeToLong(tm:String) :Long={
    val fm = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")
    val dt = fm.parse(tm)
    val aa = fm.format(dt)
    val tim: Long = dt.getTime()
    tim
  }
}import java.text.SimpleDateFormat
