java-spring-jaeger Span is not linked with spring cloud gateway

trafficstars

I am working on microservice architecture

User-------->Spring cloud gateway------------->Service A-------------->Service B

In Jaeger, It shows 2 different spans, one in gateway and other is service A --> Service B But it should be a single span ie. gateway-----> Service A----->Service B

API gateway is developed using spring cloud gateway Service A is developed using spring boot Service B is developed using spring boot

Version info for all 3 application:

compile group: 'commons-lang', name: 'commons-lang', version: '2.6' springBootVersion=2.1.4.RELEASE springDMPVersion=1.0.9.RELEASE springPlatformBomVersion=Cairo-SR8 springCloudVersion=Greenwich.SR1

I haven't really used Spring Cloud Gateway, but here is something that might help - can you try setting:

opentracing.jaeger.enable-b3-propagation = true

in Service A and Service B please and let us know what happens?

@geoand After applying this, the link between Service A and Service B is broken, Now it's showing three different spans for each application

@nitinvavdiya Unfortunately I don't have much time to look into this now (not being familiar with Spring Cloud Gateway does not help :) ). Hopefully I will soon.

@nitinvavdiya I fixed it, see pr: https://github.com/opentracing-contrib/java-spring-cloud/pull/233

Hi guys, I run into the same issue... any ideas?

We created a GlobalFilter go generate the span and pass the traceID to the next service. And it is working... but the problem is that we are creating the local spring cloud gateway span with the incoming request instead of the outgoing... that's why this solution is no good.

Does some of you how to interact with the underneath HttpClientConnect object?

I left the code explanation and also de question on stackoverglow.

Thanks in advance!
