碼頭HTTP/2客戶端掛起獲取URL

Question

我有（實際上，從jetty-project repo複製）的碼：

HTTP2Client http2Client = new HTTP2Client(); 
SslContextFactory sslContextFactory = new SslContextFactory(); 
HttpClient httpClient = new HttpClient(new HttpClientTransportOverHTTP2(http2Client), sslContextFactory); 
Executor executor = new QueuedThreadPool(); 
httpClient.setExecutor(executor); 
httpClient.start(); 

ContentResponse response = httpClient.GET("https://www.google.com/"); 

出於某種原因，它等待響應無限。它有什麼問題？我正在尋找一個http/2客戶端使用情況的工作示例來訪問某個https url。謝謝！

您可能沒有配置ALPN。

請參考ALPN documentation爲運行客戶端代碼的JVM啓用ALPN。
