Trace ID is not passed down in Dubbo application

[liunancun]

This is a Dubbo application, which consists of three parts: demo-consumer, demo-provider, and demo-test.

The calling process is
demo-consumer -> demo-provider -> demo-test

demo-consumer Configuration and code

dubbo.application.name=demo-consumer
dubbo.scan.basePackages=com.example.demo
dubbo.registry.address=zookeeper://192.168.99.214:2181
dubbo.application.qos-enable=false
dubbo.protocol.port=20883
dubbo.consumer.filter=tracing

@Configuration
@Import({ DelegatingTracingFilter.class, SpanCustomizingAsyncHandlerInterceptor.class })
public class WebZipkinConfig implements WebMvcConfigurer {

	@Resource
	private SpanCustomizingAsyncHandlerInterceptor interceptor;

	@Resource
	private Tracing tracing;

	@Override
	public void addInterceptors(InterceptorRegistry registry) {
		registry.addInterceptor(interceptor);
	}

	@Bean
	public HttpTracing httpTracing() {
		return HttpTracing.create(tracing);
	}
}

@Configuration
public class ZipkinConfig {
	@Bean
	public Tracing tracing() {
		return Tracing.newBuilder().localServiceName("consumer")
				.addSpanHandler(
						AsyncZipkinSpanHandler.create(OkHttpSender.create("http://192.168.99.214:9411/api/v2/spans")))
				.build();
	}
}

@SpringBootApplication
@RestController
public class DemoApplication {

	public static void main(String[] args) {
		SpringApplication.run(DemoApplication.class, args);
	}

	@DubboReference
	private DemoService demoService;

	@GetMapping("hello")
	public String hello() {

		demoService.hello("liunancun");

		return "hello";
	}
}

demo-provider Configuration and code

dubbo.application.name=demo-provider
dubbo.scan.basePackages=com.example.demo
dubbo.registry.address=zookeeper://192.168.99.214:2181
dubbo.protocol.port=20882
dubbo.provider.filter=tracing
dubbo.consumer.filter=tracing

@Configuration
public class ZipkinConfig {
	@Bean
	public Tracing tracing() {

				.addSpanHandler(
						AsyncZipkinSpanHandler.create(OkHttpSender.create("http://192.168.99.214:9411/api/v2/spans")))
				.build();
	}
}

@DubboService
public class DemoServiceImpl implements DemoService {

	@DubboReference
	private TestService testService;

	@Override
	public String hello(String name) {

		System.out.println("hello " + name);

		testService.test(name);

		return "hello " + name;
	}

}

demo-test Configuration and code

dubbo.application.name=demo-test
dubbo.scan.basePackages=com.example.demo
dubbo.registry.address=zookeeper://192.168.99.214:2181
dubbo.protocol.port=20881
dubbo.provider.filter=tracing

@Configuration
public class ZipkinConfig {
	@Bean
	public Tracing tracing() {
		return Tracing.newBuilder().localServiceName("test")
				.addSpanHandler(
						AsyncZipkinSpanHandler.create(OkHttpSender.create("http://192.168.99.214:9411/api/v2/spans")))
				.build();
	}
}

@DubboService
public class TestServiceImpl implements TestService {

	@Override
	public String test(String name) {

		System.out.println("test, " + name);

		return "test, " + name;
	}

}

result

Three Trace IDs appear

There are only two calls to consumer. Normally, there should be three calls

It is normal in version 2.7, but there is a problem in version 3 or above. Does it still not support Dubbo3?

[marcingrzejszczak]

Dubbo has support for micrometer observation and micrometer tracing that has a bridge for brave. You can use that
