Sleuth with webflux

See original GitHub issue

I tested sleuth with webflux and mvc. But webflux with sleuth doesn’t work properly. You can see my test example.

fcaller, fclient are made with webflux. fcaller send request to fclient. And mcaller, mclient are made with mvc. mcaller send request to mclient.

I used zipkin server with docker.

docker run -d -p 9411:9411 openzipkin/zipkin

with mvc

I send request to mcaller. and mcaller request to mclient ME -> mcaller -> mclient

It works well as I expected.

with webflux

same scenario with mvc. ME -> fcaller -> fclient

but It doesn’t record “Server Start - Server Finished” span.

In debugging mode, WebFilterTraceSubscriber.onComplete() never called. So “Server span” isn’t reported.

https://github.com/spring-cloud/spring-cloud-sleuth/blob/06ccdd60abf6f47626d4c9fe568a2440233eca67/spring-cloud-sleuth-core/src/main/java/org/springframework/cloud/sleuth/instrument/web/TraceWebFilter.java#L252-L256

Is there any problem in my usage with webflux? Or is it works well as as you intended?
