Zipkin & Sleuth, Tracer missing the createSpan method

Question

I am following the tutorial for creating tracing application zipkin and sleuth but I am having some trouble. I cannot create a span. The problem is that the method does not exist. Also I cannot find the import for the tracer.

This is what I am trying to do:

import org.springframework.cloud.sleuth.Tracer;

@Component 
public class  Test {

  @Autowired
  Tracer tracer;

  public void test (){
     Span newSpan = tracer.createSpan("test");
     //business logic
     tracer.close(newSpan);
  }



}

Why is the implementation above not working?

Answer 1

That's an old implementation. Below I have modified your code to work:

import brave.Tracing;
import brave.Span;

@Component 
public class  Test {

  @Autowired
  Tracing tracing;

  public void test (){
     Span span = tracing.tracer().nextSpan().name("name");
     //business logic
     span.finish();
  }
}
