Should new active span be created using current active span as a parent? about java-spring-web HOT 5 CLOSED

@elgris the client interceptor what is in master automatically links the correct parent. Please reopen if there is still this issue

@pavolloffay can you tell me where automatic linking is done in the interceptor? Because with tracer.buildSpan we do not inject any parent context? At least I don't see it on the master branch.

When I use rest template to make an http call, then separate trace is created for each request. I want to be able to connect it to the currently active span. Or at least be able to send headers with the request and then those headers could be used to make a parent context.

Similar was done in TracingKafkaUtils in java-kafka-client.

Statement .asChildOf(tracer.activeSpan()) is not necessary the active span should be added as parent automatically.

When you say automatically, where is that in the code exactly? I tried to look for that piece of code on the master branch, but was not successful. Currently, for me, it does not work.

The tracer implementation should do it.
