Send a request to the zipkin application, and check the logs

curl http://localhost:8098/test/1

Send a request to the jaeger application, and check the logs

curl http://localhost:8099/test/2

mn-jaeger    | 06:34:00.033 [default-nioEventLoopGroup-1-3] INFO  com.example.main.TestController - MDC:[test=test value] - controller test # 2!
mn-jaeger    | 06:34:00.034 [default-nioEventLoopGroup-1-3] INFO  com.example.main.TestService - MDC:[test=test value] - service test # 2!

traceId and spanId are not in MDC.

With the fixed version from branch fixed

curl http://localhost:8100/test/3
