1.什么zipkin
Zipkin是一款开源的分布式实时数据追踪系统（Distributed Tracking System），基于 Google Dapper的论文设计而来，由 Twitter 公司开发贡献。其主要功能是聚集来自各个异构系统的实时监控数据。Zipkin默认支持Http协议，除此之外，它还支持kafka,rabbitmq以及scribe协议：
2.搭建zipkin环境
1.获取镜像
docker pull openzipkin/zipkin2.启动
docker run --name zipkin -d -p 9411:9411 openzipkin/zipkin3.web端查看
浏览器打开 http://127.0.0.1:9411
3.代码项目
实验目的：实现监控数据上报到zipkin，并分析每个方法的执行时间

4.测试
启动Spring Boot应用
访问controller
浏览器输入http://127.0.0.1:8088/http，可以看到控制台生成traceID 和spanid

可以看到刚刚访问trace id，以及调用的3个方法耗时，以及具体的代码位置信息
