Scala 连接上的Jetty WebSocket，创建端接时不闭合的管道

我正在使用jetty websocket客户端连接到websocket服务器。在每个成功的连接上，它都会创建大约35个文件描述符，其中32个是管道。终止时，这些管道不会关闭

class AMPWebSocketClient(remoteHost: String, remoteHandler: String) {

  val logger: Logger  = LoggerFactory.getLogger(this.getClass)
  //1. Create Context
  private var masterAMPClient = new WebSocketClientContext()
                                      .setTrustStore(C.GLASS_KEY_STORE)
                                      .setPassword(C.DEFAULT_KEYSTORE_PASSWORD)
                                      .buildSecureClient

  private var client = createSession(remoteHost, remoteHandler)
  private var session: Session = _
  private var socket: MasterAMPFeeder = _

  private def createSession(remoteHost: String, remoteHandler: String): MasterAMPFeeder = {
    //2. Connect to WebSocket Server
      var future = ""
      var success = false
      var generatedURI: String = "wss://" + remoteHost + "/decoder/" + remoteHandler
    socket = new MasterAMPFeeder()

      do {
      try {
          masterAMPClient.getPolicy.setIdleTimeout(TimeUnit.DAYS.toMillis(1))
          masterAMPClient.start()
          val destURI: URI = new URI(generatedURI)
          val request: ClientUpgradeRequest = new ClientUpgradeRequest()
          val future = masterAMPClient.connect(socket, destURI, request)
          logger.debug("Before connection")
          session = future.get(C.ONE_SECOND * 15, TimeUnit.SECONDS)
          session.setIdleTimeout(TimeUnit.DAYS.toMillis(1))
          logger.debug("Waiting for GlassDecoder to accept the connection")
            socket.getLatch().await()
          logger.debug("Connected to GlassDecoder")
      } catch {
          case e: Exception => {
            logger.debug("Not able to connect to WebSocket: {}", e.getStackTrace)
            logger.warn("Retrying to connect to: {}", generatedURI)
            Thread.sleep(10 * C.ONE_MILLISECOND)
        }
      }
      } while(socket.isNotConnected)

    return socket
  }

我不知道什么是scala/akka管道，但如果它与Java线程相关，那么这听起来像是线程池和选择器的客户端默认值（在您的示例中您似乎没有配置）我如何配置线程池和选择器？@JoakimErdfelt我试图限制线程私有隐式val ec=ExecutionContext.fromExecutor（Executors.newFixedThreadPool（4））。它没有帮助。它仍然在创建32个管道。我不知道什么是scala/akka管道，但是如果它与Java线程相关，那么这听起来像是线程池和选择器的客户端默认值（在您的示例中似乎没有配置）如何配置线程池和选择器？@JoakimErdfelt我试图限制线程私有隐式val ec=ExecutionContext.fromExecutor（Executors.newFixedThreadPool（4））。它没有帮助。它仍在创建大约32个管道
