Demonstrate no logs in trace when using webclient

• Step1: Start Jaeger
• Step2: Run application and observe the logs. It will show logs as below

[   scheduling-1] c.e.demo.JaegerTraceReactiveApplication  : before task
[   scheduling-1] c.e.demo.JaegerTraceReactiveApplication  : inside getA
[   scheduling-1] c.e.demo.JaegerTraceReactiveApplication  : inside getB
[   scheduling-1] c.e.demo.JaegerTraceReactiveApplication  : after task
[ctor-http-nio-3] c.e.demo.JaegerTraceReactiveApplication  : inside api 
[ctor-http-nio-2] c.e.demo.JaegerTraceReactiveApplication  : before sending BMono
[ctor-http-nio-2] c.e.demo.JaegerTraceReactiveApplication  : inside onCompleted batest

• Step3: Navigate to a trace and inspect the logs. Following logs are missing
  • before sending BMono
  • inside onCompleted

  

Optional step.

• StepO1: Open JaegerTraceReactiveApplication.java and inspect the reactive flow
• StepO2: Uncomment lines 42

/*.exchangeFunction(clientRequest -> Mono.just(dummyResponseToAvoidPost()))*/

• Step)3: Restart application
• StepO4: Navigate to a trace in Jaeger and inspect the logs. All logs are shown

  

Analysis

Jaeger tracing does not capture logs after webclient makes http call
