无法连接到 Jetty 上的安全 Websocket 运行

Question

我有以下代码应该在独立的 Java 应用程序中设置安全的 websocket 端点（jnlp 触发）并允许我从客户端连接（Java浏览器中的脚本）使用 url：ws://localhost:8444/echo

服务器启动没有错误，但我无法连接：

WebSocket connection to 'wss://localhost:8444/echo' failed: Error in connection establishment: net::ERR_CONNECTION_CLOSED

    server = new Server();

    SslContextFactory contextFactory = new SslContextFactory();
    contextFactory.setKeyStorePath("/path/keys/keystore.jks");
    contextFactory.setKeyStorePassword("changeit");
    SslConnectionFactory sslConnectionFactory = new SslConnectionFactory(contextFactory, org.eclipse.jetty.http.HttpVersion.HTTP_1_1.toString());

    ServerConnector connector = new ServerConnector(server, sslConnectionFactory);
    connector.setPort(8444);

    ServletContextHandler contextHandler = new ServletContextHandler(ServletContextHandler.SESSIONS);
    contextHandler.setContextPath("/");
    HandlerCollection hc = new HandlerCollection();
    hc.addHandler(contextHandler);
    server.setHandler(contextHandler);

    server.addConnector(connector);

    // Add websocket servlet
    ServletHolder wsHolder = new ServletHolder("echo",new EchoSocketServlet());
    contextHandler.addServlet(wsHolder,"/echo");

    try
    {
        server.start();
        server.join();
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

如果有人能发现上述内容中的明显错误，我们将不胜感激。此外，当我删除 SslConnectionFactory 并使用非 SSL Websocket URL (ws://).

连接时，我可以成功连接到上述内容

经过大量的试验和错误、一些痛苦和这个人的一点帮助，终于让它工作了：

对于那些认为他们可能会因此得到帮助的人，我更新了服务器代码如下，并创建了一个自签名证书：此外，最后的 pièce de résistance（当使用自签名（不受信任的）证书时）是在您选择的浏览器中浏览到安全 url，并收到提示以便您可以添加例外。如果你不这样做，它将永远无法工作！！

    final int port = 5040;
    final int sslPort = 8442;

    server = new Server(port);

    SslContextFactory contextFactory = new SslContextFactory();
    contextFactory.setKeyStorePath("/Users/me/keystore");
    contextFactory.setKeyStorePassword("password");
    SslConnectionFactory sslConnectionFactory = new SslConnectionFactory(contextFactory, org.eclipse.jetty.http.HttpVersion.HTTP_1_1.toString());

    HttpConfiguration config = new HttpConfiguration();
    config.setSecureScheme("https");
    config.setSecurePort(sslPort);
    config.setOutputBufferSize(32786);
    config.setRequestHeaderSize(8192);
    config.setResponseHeaderSize(8192);
    HttpConfiguration sslConfiguration = new HttpConfiguration(config);
    sslConfiguration.addCustomizer(new SecureRequestCustomizer());
    HttpConnectionFactory httpConnectionFactory = new HttpConnectionFactory(sslConfiguration);

    ServerConnector connector = new ServerConnector(server, sslConnectionFactory, httpConnectionFactory);

    connector.setPort(sslPort);
    server.addConnector(connector);

    ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
    context.setContextPath("/");

    try
    {
        // Add websocket servlet
        ServletHolder wsHolder = new ServletHolder("ws-echo", new EchoSocketServlet());
        context.addServlet(wsHolder,"/echo");

        server.setHandler(context);

        server.start();
        server.dump(System.err);
        server.join();
    }
    catch (Throwable t)
    {
        t.printStackTrace(System.err);
    }
