Jetty 9.x 中Connectors 中的Connection 对象去哪儿了？

Question

当我尝试从 Jetty 8.1.12 迁移到 Jetty 9.4.x 时，由于以下问题出现错误。

我们使用 connector.getConnection() 方法。而且我没有在 Jetty 9 中找到任何替代品。4.x。

这是

的后续问题

我们使用 connector.getConnection() 获取 inet 套接字地址。

    private InetSocketAddress findFirstInetConnector(Server server) {
        Connector[] connectors = server.getConnectors();
        if (connectors != null) {
            for (Connector connector : connectors) {
                Object connection = connector.getConnection();
                if (connection instanceof ServerSocketChannel) {
                    SocketAddress address = ((ServerSocketChannel) connector.getConnection()).socket().getLocalSocketAddress();
                    if (address instanceof InetSocketAddress) {
                        return (InetSocketAddress) address;
                    }
                } else if (connection instanceof ServerSocket) {
                    SocketAddress address = ((ServerSocket) connector.getConnection()).getLocalSocketAddress();
                    if (address instanceof InetSocketAddress) {
                        return (InetSocketAddress) address;
                    }
                }
            }
        }
        return null;
    }

谁能帮我找到相同的替代品。

一个连接器没有连接了。

你不能再随意地从中得到一个 SocketAddress 或 InetSocketAddress。

为什么？

嗯，我们有逻辑连接器、物理连接器、非网络连接器、网络连接器、服务器连接器、本地连接器、基于管道的连接器、基于 jni 的连接器、基于 unixsocket 的连接器等...

您必须根据 started 和 运行[=28= 上的信息创建您想要的 InetSocketAddress ] 连接器（例如 NetworkConnector localPort 和 host）。

要遍历连接器信息，您可以...

for (Connector connector : server.getConnectors())
{
    // What is the connector name (can be null or unset)
    String connectorName = connector.getName();

    // What is the declared protocol default for this connector?
    String defaultProtocol = connector.getDefaultConnectionFactory().getProtocol();
    // What other features does this connector handle?
    for (ConnectionFactory connectionFactory : connector.getConnectionFactories())
    {
        // List of protocols handled by this specific connection factory for this specific connector
        connectionFactory.getProtocols();

        if (connectionFactory instanceof SslConnectionFactory)
        {
            // this can handle TLS/SSL based connections
        }

        if (connectionFactory instanceof HttpConnectionFactory)
        {
            // this can handle http protocols

            // get the http specific configuration
            HttpConfiguration httpConfig = ((HttpConnectionFactory) connectionFactory).getHttpConfiguration();
            // what port is recognized as secure
            httpConfig.getSecurePort();
            // what scheme is recognized as secure
            httpConfig.getSecureScheme();
        }

        if (connectionFactory instanceof HTTP2ServerConnectionFactory)
        {
            // can handle encrypted http/2 protocols (and alpn features)
        }

        if (connectionFactory instanceof HTTP2CServerConnectionFactory)
        {
            // this can handle http/2's special clear-text "h2c" protocol (no alpn features)
        }
    }

    if (!connector.isRunning())
    {
        // no information below can be trusted unless the connector is started
        continue;
    }

    if (connector instanceof NetworkConnector)
    {
        // we have a network capable connector
        NetworkConnector networkConnector = (NetworkConnector) connector;
        // What interface is it listening on?
        String interfaceName = networkConnector.getHost();
        // What local port is it bound to?
        int localPort = networkConnector.getLocalPort();
    }
}
