Question

my code: https://github.com/nikita111100/gRPC-vs-REST

Answer 1

it works for me

@Configuration

public class TracingConfig {

@GrpcGlobalClientInterceptor
TracingClientInterceptor tracingInterceptor(Tracer tracer) {
    return TracingClientInterceptor
            .newBuilder()
            .withTracer(tracer)
            .build();
}
