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))

f.respond(_ => minTimeDelta match {
case Some(minTime) => DefaultTimer.onceAfter(minTime)(pending.remove(path, 1))
case None => pending.remove(path, 1)
