带 SSL 的 Jetty HttpClientTransportOverHTTP2

Question

我正在尝试使用 Jetty 的 HttpClientTransportOverHTTP2 发出简单的 GET 请求，但它失败了。这是我的代码：

import org.eclipse.jetty.client.HttpClient;
import org.eclipse.jetty.client.api.ContentResponse;
import org.eclipse.jetty.http2.client.HTTP2Client;
import org.eclipse.jetty.http2.client.http.HttpClientTransportOverHTTP2;
import org.eclipse.jetty.util.ssl.SslContextFactory;

public class JettyClientExample {

    public static void main(String[] args) throws Exception {
        HttpClientTransportOverHTTP2 clientTransport = new HttpClientTransportOverHTTP2(new HTTP2Client());
        HttpClient client = new HttpClient(clientTransport,  new SslContextFactory(true));
        client.start();
        ContentResponse response = client.GET("https://http2.akamai.com");
        System.out.println("Version: " + response.getVersion());
        System.out.println("Status: " + response.getStatus());
        System.out.println("Content: " + response.getContentAsString());
    }
}

这是我在行 client.GET("https://http2.akamai.com")

中得到的异常

我正在使用版本 9.3.3.v20150827，并且我将 ALPN JAR 放入我的引导类路径 -Xbootclasspath/p:<path>。

出于某种原因，我没有在互联网上找到任何使用 SSL HttpClientTransportOverHTTP2 的工作示例。

我错过了什么？
