以下是您提供的代码的翻译部分：
@RestController
@Component
public class Greeting {
private static final Logger logger = Logger.getLogger(Greeting.class.getName());
@Autowired
Tracer tracer;
@RequestMapping("/greeting")
public String greeting() {
logger.info("Hello info from from spring sleuth");
logger.info("tracer is -----> " + tracer.currentSpan().context().traceIdString());
System.out.println("tracer-id :" + tracer.currentSpan().context().traceIdString());
return "Hello";
}

英文:
I am calling my Springboot app from another micro service to get the trace & span id's but getting error while starting the app.
What I want to do is create Trace & Span in app1 and then call app2 and get the Trace id passed from app1 in app2. In app1 I am able to get the trace & span but in app2 where I want to fetch that trace its failing. I have tried to refer this.
Error that I get is:
> Description:
>
> Parameter 0 of constructor in com.test.demo1.filter.MyFilter required a bean of type 'brave.Tracer' that could not be found.
>
> Action:
>
> Consider defining a bean of type 'brave.Tracer' in your configuration."
I also tried creating the bean but is giving error "The constructor Tracer() is undefined"
Below is my simple RestController & pom.xml
package com.test.demo1.controller;
import java.util.logging.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import brave.Tracer;
@RestController
@Component
public class Greeting {
private static final Logger logger = Logger.getLogger(Greeting.class.getName());
@Autowired
Tracer tracer;
@RequestMapping("/greeting")
public String greeting() {
logger.info("Hello info from from spring sleuth");
logger.info("tracer is -----> "+tracer.currentSpan().context().traceIdString());
System.out.println("tracer-id :"+ tracer.currentSpan().context().traceIdString());
return "Hello";
}
}

得分: 1
你已经提供了版本为1.0.0的Sleuth，该版本已经有几年了。请访问start.spring.io生成一个项目，并将Sleuth作为其依赖。然后你就可以确保没有手动混淆依赖关系。

英文:
You've provided Sleuth in version 1.0.0 which is a couple of years old. Please go to start.spring.io to generate a project with Sleuth as its dependency. Then you'll be sure that you don't have mixed up the dependencies manually.
