    <dependency>
            <groupId>org.springframework.kafka</groupId>
            <artifactId>spring-kafka</artifactId>
    </dependency>

        spring.sleuth.sampler.probability=1 

        spring.application.name=dummy

        spring.zipkin.baseUrl=http://localhost:9411

        spring.zipkin.sender.type=kafka

@SpringBootApplication
public class UserApplication {

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

}

@GetMapping("/hello")
public String sayHello() {
    log.info("hey im a log");
    return "hello";
}

当我创建spring.Zipkin.sender.type=web时，Zipkin dashboard中显示了跟踪，这里有没有我缺少的东西。

Answer 1

好的，我终于意识到我用这个命令启动zipkin服务器时犯了什么错误

 java -jar zipkin-server-2.16.2-exec.jar

但我没有指定我的Zipkin服务器，我的Kafka运行的地方，所以当我指定时

 set KAFKA_BOOTSTRAP_SERVERS=localhost:9092
 java -jar zipkin-server-2.16.2-exec.jar 

奏效了
