Micrometer Tracing not working with Spring Boot 2.2.2

Question

I am using the spring boot 2.2.2.Release version.

this is my controller class.

@RestController
public class HelloController {

    private static final Logger LOGGER = LogManager.getLogger(HelloController.class);
    @GetMapping(value = "{userId}")
    public String test(@PathVariable("userId") String userId){
        LOGGER.info("user =  {}",userId);
        return "ok";
    }
}

this is my pom.xml and in the detail i have added the micrometer tracing library and use the spring boot 2.2.2 version. and also i use the log4j2 library.

            </plugin>
        </plugins>
    </build>

this is the pattern and i added [%X{traceId},%X{spanId}].

appender.console.layout.pattern = [%d{yyy-MM-dd HH:mm:ss:SSS}] [%X{traceId},%X{spanId}] [%p] - %l - %m%n

the log output is :

[2023-07-11 10:45:49:889] [,] [INFO] - com.example.loglama.controller.HelloController.test(HelloController.java:18) - user =  demo123

if you can see the traceId and spaceId are empty. the company doesn't want to upgrade the spring boot version for that I have to fix this issue with this version. How can fix this issue ?

You only added dependencies as there is no auto configuration for Micrometer in this version of Spring Boot you have to manually register all necessary components. — M. Deinum, Jul 11 '23 at 07:57
Thank you so much for your answer. what do you mean manually register necessary components ? I didn't find do you have any links,pls ? — Sezer Aydın, Jul 11 '23 at 08:43
Check what Spring Boot 3 is registering for components in the context to enable micrometer tracing, you will need to replicate that for Spring Boot 2.2. — M. Deinum, Jul 11 '23 at 08:46
sorry, I still didn't understand what is registering for components in the context to enable micrometer tracing. they said that just add the library and use it in the all tutorial. am I missing something? — Sezer Aydın, Jul 11 '23 at 08:59
Why do you think adding some dependencies, write a log line will automagically work? Support for Micrometer was **added in Spring Boot 3**, so if you try it with **Spring Boot 2** this won't automagically work. You will need to setup micrometer yourself. — M. Deinum, Jul 11 '23 at 09:01

If you want Distributed Tracing and if you are on:

Spring Boot 2.7.x -> you should use Spring Cloud Sleuth
Spring Boot 3.x. -> you should use Micrometer Tracing

(Boot 2.2.x is very old and no longer supported, you should upgrade.)
