新建docker目录
新建docker-compose.yml

version: "3.1"
services:

EXPOSE 9411

新建src/main/java目录
新建com.funtl.cbj.zipkin包
新建ZipKinApplication启动类

package com.funtl.cbj.zipkin;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import zipkin.server.internal.EnableZipkinServer;


@SpringBootApplication
@EnableEurekaClient
@EnableZipkinServer
public class ZipKinApplication {
    public static void main(String[] args) {
        SpringApplication.run(ZipKinApplication.class, args);
    }

}
