Spring Boot集成zipkin快速入门Demo

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/zipkin

2.启动

docker run --name zipkin -d -p 9411:9411 openzipkin/zipkin

3.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

config

java">package com.et.zipkin.config;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.ClientHttpRequestFactory;
import org.springframework.http.client.SimpleClientHttpRequestFactory;

@Configuration
public class RestTemplateConfig {@Beanpublic RestTemplate restTemplate(ClientHttpRequestFactory factory){return new RestTemplate(factory);}@Beanpublic ClientHttpRequestFactory simpleClientHttpRequestFactory(){SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();factory.setReadTimeout(5000);//unit is msfactory.setConnectTimeout(5000);//unit is msreturn factory;}
}

以上只是一些关键代码，所有代码请参见下面代码仓库

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
