Undertow配置TCP保持活动参数

如何解决Undertow配置TCP保持活动参数

我将Undertow用作Java应用程序的服务器，我试图使用以下命令设置TCP Keep Alive选项 Undertow.Builder的setSocketoptions（）方法（请参见下面的代码）。

为了进行测试，我正在发送1条消息，然后保持连接处于活动状态而不在其上发送任何内容，以便可以观察到TCP-KeepAlive。 但是由于设置的参数，由于无法在tcpdump捕获中看到任何保持活动的数据包，因此无法设置这些字段。

Undertow是否支持设置这些参数？ 如果是，这是在Undertow中配置TCP Keep Alive参数的正确方法还是我遗漏了什么？

@Bean
public ServletWebServerFactory undertowFactory() {
   UndertowServletWebServerFactory undertowFactory = new UndertowServletWebServerFactory();

   // listen to http and enable http2
   undertowFactory.addBuilderCustomizers((Undertow.Builder builder) -> {
        builder.setWorkerThreads(maxWorkerThreads);
        builder.addHttpListener(httpPort,"0.0.0.0");
        builder.setServerOption(UndertowOptions.ENABLE_HTTP2,isHTTP2Enabled);
        builder.setServerOption(UndertowOptions.IDLE_TIMEOUT,3600000);
        builder.setSocketoption(Options.KEEP_ALIVE,true);
        builder.setSocketoption(Option.simple(StandardSocketoptions.class,"SO_KEEPALIVE",Boolean.class),true);
        builder.setSocketoption(Option.simple(ExtendedSocketoptions.class,"TCP_KEEPINTERVAL",Integer.class),10);
        builder.setSocketoption(Option.simple(ExtendedSocketoptions.class,"TCP_KEEPIDLE","TCP_KEEPCNT",10);
   });
   
   logger.info("Undertow Max Worker Threads: " + maxWorkerThreads);
   
   undertowFactory.addDeploymentInfoCustomizers(deploymentInfo -> {
                  deploymentInfo.addInitialHandlerChainWrapper(gracefulShutdown());
   });
   // redirect http to https
   if (redirectHTTP == true) {
          undertowFactory.addDeploymentInfoCustomizers(deploymentInfo -> {
           deploymentInfo.addSecurityConstraint(new SecurityConstraint()
                         .addWebResourceCollection(new WebResourceCollection().addUrlPattern("/*"))
                         .setTransportGuaranteeType(TransportGuaranteeType.CONFIDENTIAL)
                         .setEmptyRoleSemantic(SecurityInfo.EmptyRoleSemantic.PERMIT))
                         .setConfidentialPortManager(exchange -> httpsPort);
          });
   }

   return undertowFactory;
}
