应用程序在尝试获取 Sleuth 的踪迹时失败并显示 "required a bean of type 'brave.Tracer' that could not be found"

Question

我正在从另一个微服务调用我的 Springboot 应用程序以获取跟踪和跨度 ID，但在启动应用程序时出现错误。我想要做的是在 app1 中创建 Trace & Span，然后调用 app2 并在 app2 中获取从 app1 传递的 Trace id。在 app1 中，我能够获取跟踪和跨度，但在 app2 中，我想获取跟踪失败的地方。我试过参考 this.

我得到的错误是：

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"

下面是我简单的 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";
    }

}

Answer 1

您在 1.0.0 版本中提供了 Sleuth，该版本已有几年历史。请到 start.spring.io 生成一个以 Sleuth 作为依赖项的项目。然后您将确定您没有手动混淆依赖项。
