### Pre-check - [x] I am sure that all the content I provide is in English. ### Search before asking - [x] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version org.apache.dubbo:dubbo:3.3.4 org.apache.dubbo:dubbo-spring-boot:3.3.4 javac 21.0.6 ### Steps to reproduce this issue The same problem occurs when configuring Zipkin tracing, mainly in the context switching of webflux. org.apache.dubbo.spring.boot.autoconfigure.observability.DubboMicrometerTracingAutoConfiguration#dubboServerTracingObservationHandler As long as the above bean is registered, the Webflux context switching will fail. No need to configure any link tracking, just turn on the tracking switch. ### What you expected to happen 2025-05-02T15:58:59.842Z DEBUG 28890 --- [io-42010-exec-1] [ ] o.s.w.s.a.HttpWebHandlerAdapter : [7a06cd92] HTTP POST "/graphql" 2025-05-02T15:58:59.861Z TRACE 28890 --- [io-42010-exec-1] [b3e0cb9fb1d6e22ac63ef6ce27a5e30a-1ca5e0e0cdfadcc1] o.s.h.s.r.ServletHttpHandlerAdapter : [7a06cd92] onError: java.lang.ClassCastException: class org.springframework.http.server.reactive.observation.ServerRequestObservationContext cannot be cast to class org.apache.dubbo.tracing.context.DubboServerContext (org.springframework.http.server.reactive.observation.ServerRequestObservationContext and org.apache.dubbo.tracing.context.DubboServerContext are in unnamed module of loader 'app') 2025-05-02T15:58:59.861Z TRACE 28890 --- [io-42010-exec-1] [b3e0cb9fb1d6e22ac63ef6ce27a5e30a-1ca5e0e0cdfadcc1] o.s.h.s.r.ServletHttpHandlerAdapter : [7a06cd92] Setting ServletResponse status to 500 Server Error ### Anything else application.yaml ```yaml spring: application: name: gateway-admin main: web-application-type: reactive config: import: - 'optional:classpath:application-base.yml' - 'optional:classpath:application-common.yml' - 'optional:classpath:application-self.yml' - 'optional:classpath:application-${spring.profiles.active}-common.yml' - 'optional:classpath:application-${spring.profiles.active}.yml' - 'optional:zookeeper:' profiles: active: ${APP_PROFILE:local} ``` application-base.yaml ```yaml spring: main: banner-mode: off reactor: context-propagation: auto cloud: zookeeper: connect-string: ${APP_ZOOKEEPER_CONNECT_STRING:localhost:2181} graphql: graphiql: enabled: true websocket: path: /graphql redis: redisson: config: | clusterServersConfig: nodeAddresses: - "valkey://127.0.0.1:7000" checkSlotsCoverage: true connectTimeout: 30000 subscriptionsPerConnection: 5 threads: 16 nettyThreads: 32 transportMode: "NIO" dgs: graphql: dgs-response-headers: enabled: false dubbo: application: name: dubbo-${spring.application.name} logger: slf4j enable-empty-protection: true enable-file-cache: false qos-enable: false register-mode: instance preferred-protocol: tri auto-trust-serialize-class: true trust-serialize-class-level: 10 serialize-check-status: DISABLE check-serializable: false protocol: name: tri port: -1 timeout: 20000 serialization: fastjson2 triple: rest: json-framework: fastjson2 consumer: check: false timeout: 20000 serialization: fastjson2 provider: check: false timeout: 20000 serialization: fastjson2 registry: address: zookeeper://${spring.cloud.zookeeper.connect-string} config-center: address: ${dubbo.registry.address} metadata-report: address: ${dubbo.registry.address} metrics: aggregation: enabled: true histogram: enabled: true tracing: propagation: type: W3C tracing-exporter: zipkin-config: connect-timeout: 1s read-timeout: 10s endpoint: http://127.0.0.1:9411/api/v2/spans sampling: probability: 1 enabled: true management: tracing: sampling: probability: 1.0 zipkin: tracing: export: enabled: true endpoint: http://127.0.0.1:9411/api/v2/spans server: port: 0 shutdown: graceful lifecycle: timeout-per-shutdown-phase: 20s logging: include-application-name: false level: root: INFO org.springframework.boot.context.config: DEBUG org.springframework.context.support.PostProcessorRegistrationDelegate: ERROR org.apache.dubbo.spring.boot.context.event.WelcomeLogoApplicationListener: INFO org.springframework.http.server.reactive: TRACE sa-token: is-print: false check-same-token: true log-level: DEBUG is-log: true debug: true ``` ### Are you willing to submit a pull request to fix on your own? - [ ] 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.
