### Search before asking - [x] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar issues. ### Apache SkyWalking Component Java Agent (apache/skywalking-java) ### What happened 1. In Gateway, the filters use TraceContext.putCorrelation to place custom IDs. ```java String custom_request_id = request.getHeaders().getFirst("custom_request_id"); if (StringUtil.isNotEmpty(custom_request_id)) { TraceContext.putCorrelation("custom_request_id", custom_request_id); } ``` 2. In the subsequent user services, the custom ID cannot be obtained. ```java Optional<String> op = TraceContext.getCorrelation("custom_request_id"); ``` ### What you expected to happen I think it's because of Gateway's webflux. Because for regular services, such as when the user service calls TraceContext.putCorrelation, and then through Feign calls the order service, the order service can obtain it. ### How to reproduce - springboot：2.3.12.RELEASE - gateway：2.2.9.RELEASE - skywalking-java-agent：9.3.0 ### Anything else _No response_ ### Are you willing to submit a pull request to fix on your own? - [x] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
