如何使用ALPN使用SPDY运行Jetty？

Question

我回到了JDK8和Jetty和SPDY，我看到现在Jetty 9.2支持ALPN协议而不是NPN协议（参见我的问题，如何在JDK8上运行Jetty和SPDY？）。所以我设置了bootclasspath:

java -Xbootclasspath/p:c:/jars/alpn-boot/alpn-boot-8.0.0.v2014031 ...

但现在我有个例外：

Exception in thread "xyz.server" java.lang.NoClassDefFoundError:
        org/eclipse/jetty/npn/NextProtoNego$ServerProvider
    at java.lang.ClassLoader.defineClass1(Native Method)

    ...

我使用Java版本“1.8.0_05”和jetty 9.2.2.v20140723。

SSLconnector = new HTTPSPDYServerConnector(server, sslContextFactory);

Answer 1

HttpSpdyServerConnector未更新为ALPN，并且当前对NPN的使用进行了硬编码。

为了将ALPN与SPDY一起使用，您必须以以下方式配置ServerConnector:

SslContextFactory sslContextFactory = new SslContextFactory();
HttpConfiguration httpConfig = new HttpConfiguration();

SslConnectionFactory ssl = new SslConnectionFactory(sslContextFactory, "alpn");
ALPNServerConnectionFactory alpn = new ALPNServerConnectionFactory("spdy/3", "http/1.1");
alpn.setDefaultProtocol("http/1.1");
HTTPSPDYServerConnectionFactory spdy = new HTTPSPDYServerConnectionFactory(SPDY.V3, httpConfig);
HttpConnectionFactory http = new HttpConnectionFactory(httpConfig);

Server server = new Server();
ServerConnector connector = new ServerConnector(server, new ConnectionFactory[]{ssl, alpn, spdy, http});

server.start();
