使用 http2 的 Jetty ssl 工厂不起作用

Question

我有一个使用 jetty 的简单 spring 启动项目。

我运行在端口 443 上使用 http1.1 就好了

@Bean(name = "containerCustomizer")
public WebServerFactoryCustomizer containerCustomizer()
{
    return (container -> ((JettyServletWebServerFactory) container).addServerCustomizers(server -> {
        // HTTPS
        SslContextFactory.Server sslContextFactory = new SslContextFactory.Server();
        sslContextFactory.setKeyStoreResource(Resource.newResource(
                getClass().getClassLoader().getResource("keystore.jks")));
        sslContextFactory.setKeyStorePassword("password");
        sslContextFactory.setProtocol("TLS");
        sslContextFactory.setKeyStoreType("JKS");

        HttpConfiguration https = new HttpConfiguration();
        https.addCustomizer(new SecureRequestCustomizer());
        SslConnectionFactory sslFactory = new SslConnectionFactory(sslContextFactory,
                                                                   HttpVersion.HTTP_1_1.asString());
        ServerConnector sslConnector = new ServerConnector(server, sslFactory, new HttpConnectionFactory(https));
        sslConnector.setPort(443);
        server.setConnectors(new Connector[] {sslConnector});
    }));
}

然而，一旦我通过将 HttpVersion.HTTP_1_1.asString() 替换为 HttpVersion.HTTP_2.asString() 更改为 HTTP2，我就会得到异常

Answer 1

仅更改版本字符串是不够的。

您还需要...

ALPNServerConnectionFactory - 用于处理选择 HTTP/2 协议的 TLS 层（称为 ALPN）
HTTP2ServerConnectionFactory - 使用 HTTP/2 协议

如 embedded / Http2Server.java example

中所见

关键是您将连接类型链接在一起，ALPN 到 HTTP2 到 HTTPS。

// SSL Context Factory for HTTPS and HTTP/2
SslContextFactory sslContextFactory = new SslContextFactory.Server();
// configure sslContextFactory

// HTTPS Configuration
HttpConfiguration httpsConfig = new HttpConfiguration(httpConfig);
httpsConfig.addCustomizer(new SecureRequestCustomizer());

// HTTP/2 Connection Factory
HTTP2ServerConnectionFactory h2 = new HTTP2ServerConnectionFactory(httpsConfig);

ALPNServerConnectionFactory alpn = new ALPNServerConnectionFactory();
alpn.setDefaultProtocol(http.getDefaultProtocol());

// SSL Connection Factory
SslConnectionFactory ssl = new SslConnectionFactory(sslContextFactory, alpn.getProtocol());

// HTTP/2 Connector
ServerConnector http2Connector =
    new ServerConnector(server, ssl, alpn, h2, new HttpConnectionFactory(httpsConfig));
http2Connector.setPort(securePort);
server.addConnector(http2Connector);

使用 http2 的 Jetty ssl 工厂不起作用

Jetty ssl factory using http2 doesn't work

java

ssl

jetty

spring-boot

jetty-9
