Segment IDs are different as they are in different threads. This is expected case in the Java agent. |

I don't have any spring gateway experience, I have repeated thus many times in many issues. It is ok you keep this public here, wait for someone could help, but I am not capable to do that. |

There are gateway tesr scenario in the code bases. You could find out how it is tested, and whether your cases and versions are covered. Someone reported weeks ago, new gateway may have different behavior, if so, we rely on new patch from someone to fix this. |

The local environment is easy to test, just like the main question, because the gateway link was interrupted prematurely, two traceids were generated, and the downstream service regenerated one traceid |

Apache SkyWalking Component
Java Agent (apache/skywalking-java)
What happened
my project use spring boot 3.2， spring-could-starter-gateway version is 4.1.5
I use skywalking agent version is 9.3.0， oapserver version is 9.3.0
I put the option-plugin “apm-spring-cloud-gateway-4.x-plugin-9.3.0.jar” and “apm-spring-webflux-6.x-plugin-9.3.0.jar” into the agent dir。
Then I conducted tests and found the following issues：
In the gateway service, a request is split into two spans, as shown in the following figure. SpringCloudGateway/RoutingFilter and /testsk/api/inner/login/loginPwd are the same request, and you can see that their trace IDs are the same, but they are displayed as two on SK UI. Upon closer inspection, it is found that their segment IDs are different. Normally, they are all on the same gateway instance, and the segmentation ID should be consistent。
The downstream service user, traceid of the gateway is completely different from that of the gateway, and has not received the traceid passed down by the gateway
So, my problem is that there is a problem with the trace passing inside the gateway. I traced the source code of the agent and found that in NettyRoutingFilterInterceptor, the afterMethod was executed before the subsequent call was initiated, causing ContextManager. stopSpan();. After exiting span, FHIR FinalizerSendInterceptor was executed, and ContextManager. isActive() became null, causing the traceid not to be passed down.
I don't know if I debugged it wrong, but I hope the trace information can be processed correctly within the gateway. I hope everyone can help me
