如何使用Okhttp3通过特定的网络接口路由请求？

Question

我们正在使用OkHttp3 Client将请求发送到Jetty Http / 2服务器。我们希望通过客户端的特定网络接口路由请求。

我们尝试如下重写2个参数createSocket（InetAddress host，int port）方法

client = new OkHttpClient.Builder()
 .socketFactory(new SocketFactory() {
  final SocketFactory defaultSocketFactory = SocketFactory.getDefault();

  @Override
  public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
   LOG.info("4 argument create socket invoked {} {} {} {}", address, port, localAddress, localPort);
   return defaultSocketFactory.createSocket(address, port, localAddress, localPort);
  }

  @Override
  public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
   LOG.info("Another 4 argument create socket invoked {} {} {} {}", host, port, localHost, localPort);
   return defaultSocketFactory.createSocket(host, port, localHost, localPort);
  }

  @Override
  public Socket createSocket(InetAddress host, int port) throws IOException {
   LOG.info("Expected Create socket invoked {} {} ", host, port);
   return defaultSocketFactory.createSocket(InetAddress.getByName(dnsIPAddress), port);
  }

  @Override
  public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
   LOG.info("Other 2 Argument Create socket invoked {} {} ", host, port);
   return defaultSocketFactory.createSocket(host, port);
  }
 })
 .connectTimeout(6000, TimeUnit.MILLISECONDS)
 .retryOnConnectionFailure(true)
 .readTimeout(5000, TimeUnit.MILLISECONDS)
 .writeTimeout(5000, TimeUnit.MILLISECONDS)     
 .build();

为简洁起见，省略了构建SSL上下文的操作。

以上覆盖方法是否正确？我们没有取得预期的结果吗？

我们的需要是，请求应该从客户端通过指定的IP和端口进行路由。
