示例1: Throttler

//设置package包名称以及导入依赖的类
package se.gigurra.leavu3.util

import com.google.common.collect.ConcurrentHashMultiset
import com.twitter.util.{Duration, Future}


case class Throttler(maxConcurrentRequestsPerResource: Int = 1) {

  private val pending = ConcurrentHashMultiset.create[String]()

  def access[T](path: String,
                minTimeDelta: Option[Duration])
               (f: => Future[T]): Future[T] = {

    val prevAccessCount = pending.add(path, 1)
    if (prevAccessCount >= maxConcurrentRequestsPerResource) {
      pending.remove(path, 1)
      Future.exception(Throttled(path))
    } else {
      f.respond(_ => minTimeDelta match {
        case Some(minTime) => DefaultTimer.onceAfter(minTime)(pending.remove(path, 1))
        case None => pending.remove(path, 1)
      })
    }
  }
}

case class Throttled(id: String) extends RuntimeException(s"Throttled request '$id' (perhaps already pending?)")
