different traceId every new http request in spring cloud sleuth

Question

Recently, I started with spring cloud sleuth to trace the request in the application, and I wrote sample project to test this feature, but when the application is run, the log shows that there are different trace ids for every new http request.

and here is may code: Config.java

package com.cloud;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
@ComponentScan()
@EnableAutoConfiguration()
@EnableWebMvc
public class Config {
}

Controller.java

package com.cloud;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.sleuth.Span;
import org.springframework.cloud.sleuth.SpanAccessor;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@RestController
public class Controller {

@Autowired
SpanAccessor spanAccessor;
@Autowired
RestTemplate restTemplate;
int port = 8080;
private static final Logger LOGGER = LoggerFactory.getLogger(Controller.class);

@RequestMapping("/")
public String hi() throws InterruptedException {
    LOGGER.debug("you called hi");
    debug();
    String s = this.restTemplate
            .getForObject("http://localhost:" + this.port + "/cloud/hi2", String.class);
    return "hi/" + s;
}

@RequestMapping("/hi2")
public String hi2() throws InterruptedException {
    LOGGER.debug("you called hi2");
    debug();
    return "welcome";
}

public void debug(){
    Span span = spanAccessor.getCurrentSpan();
    LOGGER.info("span id is "+span.getSpanId()+" and trace id is "+span.getTraceId());
}

@Bean
public RestTemplate restTemplate(){
    return new RestTemplate();
}
}

and here is log:

you called hi: span id is 6716502497271349964 and trace id is 6716502497271349964
you called hi2: span id is -4542377791493777157  and trace id is -4542377791493777157

Which version of sleuth are you using? Can you post a sample somewhere on Github so that we can try to see what's going on? — Marcin Grzejszczak, Feb 11 '17 at 16:32
here is the url: https://github.com/IbrahimAl-Zreqat/cloud-sleuth.git thanks — Ibrahim, Feb 11 '17 at 19:16
I see that you have some really old school way of packaging and setting up the app... Have you tried running this as two separate apps? Maybe your issues are related to calling your own app from the same thread? I'll check it out on Monday cause I'm writing from my mobile — Marcin Grzejszczak, Feb 11 '17 at 19:22
Ok I will try, but I need to ask you that, can I use spring-cloud-sleuth without @SpringBootApplication annotation? , cause I tried it with spring boot application and all things go smoothly — Ibrahim, Feb 11 '17 at 19:28
I really doubt it. Theoretically you could set everything up yourself but I don't guarantee that it will work. So let's assume that the answer is no — Marcin Grzejszczak, Feb 11 '17 at 19:31

i copy/paste your code and it works, but i should mention some diferences:

first and most important, i run it with a main witch of course have and springboot anotation:

@SpringBootApplication(scanBasePackages="com.cloud")

second, i delete your Config class, becaouse it doesnt do anything.

thirt, mi spring version its 1.5.1.RELEASE and the spring cloud version its Dalston.BUILD-SNAPSHOT

this are the logs:

2017-03-07 10:48:29.716 INFO [traceId,2488a4c8d3f7238a,2488a4c8d3f7238a,false] 4179 --- [nio-8080-exec-1] com.cloud.Controller : span id is 2632535164654658442 and trace id is 2632535164654658442 2017-03-07 10:48:45.162 INFO [traceId,2488a4c8d3f7238a,f5e476485b30fd85,false] 4179 --- [nio-8080-exec-2] com.cloud.Controller : span id is -728327186587517563 and trace id is 2632535164654658442

Yes, this works only if I used @Springbootapplication annotation, I moved to use spring boot with the application worked on and all things are good — Ibrahim, Mar 08 '17 at 18:59
