これは、Jetty 9.2.3 サーバー構成であり、その後にサーバーで取得した「java.util.concurrent.TimeoutException」スタック トレースが続きます。
シナリオ: 私たちの開発環境では、一度に 25 の同時リクエストを常に Jetty サーバーに送信しており、すべてではなく一部のリクエストで「java.util.concurrent.TimeoutException」例外がすぐに発生します。
例外: 完全なスタック トレースを以下に貼り付けます。http 要求本文で部分的な json 要求を読み取った後に例外が発生し、残りの json 要求が http 要求の入力ストリームを通過しないため、ミリ秒単位のアイドル タイムアウトが発生してタイムアウトになる IO ブロックが発生します。
タイムアウト例外を引き起こしているどこが間違っていますか? ご意見をお聞かせください。ありがとうございました。
サーバー構成:
//new ExecutorThreadPool(corePoolSize, maxPoolSize, keepAliveTimeout, TimeUnit.SECONDS)
Server server = new Server(new ExecutorThreadPool(25, 50, 30, TimeUnit.SECONDS));
HttpConfiguration configuration = new HttpConfiguration();
configuration.setRequestHeaderSize(8192);
LowResourceMonitor lowResourceMonitor = new LowResourceMonitor(server);
lowResourceMonitor.setLowResourcesIdleTimeout(150);
lowResourceMonitor.setMaxConnections(700);
server.addBean(lowResourceMonitor);
ServerConnector connector = new ServerConnector(server, new HttpConnectionFactory(configuration));
connector.setHost(host);
connector.setPort(port);
connector.setIdleTimeout(300);
connector.setAcceptQueueSize(256);
connector.setReuseAddress(true);
connector.accept(1);
server.setConnectors(new Connector[] { connector });
例外：
