Spring Boot集成zipkin快速入门Demo

1.什么zipkin

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

controller

package com.et.zipkin.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

import java.net.URI;
import java.util.HashMap;
import java.util.Map;
@RestController
public class HelloWorldController {
    private static Logger log = LoggerFactory.getLogger(HelloWorldController.class);


    @Autowired
    private RestTemplate restTemplate;

    @RequestMapping("ping")
    public Object ping() {
        log.info("进入ping");
        return "pong study";
    }

    @RequestMapping("log")
    public Object log() {
        log.info("this is info log");
        log.error("this is error log");
        log.debug("this is debug log");
        log.warn("this is warn log");
        log.trace("this is trace log");

    }

    @RequestMapping("http")
    public Object httpQuery() {

        String studyUrl = "http://localhost:8088/ping";
        URI studyUri = URI.create(studyUrl);
        String study = restTemplate.getForObject(studyUri, String.class);
        log.info("study:{}", study);

        String floorUrl = "http://localhost:8088/log";
        URI floorUri = URI.create(floorUrl);
        String floor = restTemplate.getForObject(floorUri, String.class);
        log.info("floor:{}", floor);

        String roomUrl = "http://localhost:8088/ping";
        URI roomUri = URI.create(roomUrl);
        String room = restTemplate.getForObject(roomUri, String.class);
        log.info("room:{}", room);
        return study + "-------" + floor + "-------" + room + "-------";
    }


}

config

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;
import org.springframework.web.client.RestTemplate;

/**
 * RestTemplate  config
 */
@Configuration
public class RestTemplateConfig {
 
    @Bean
    public RestTemplate restTemplate(ClientHttpRequestFactory factory){
        return new RestTemplate(factory);
    }
 
    @Bean
    public ClientHttpRequestFactory simpleClientHttpRequestFactory(){
        SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
        factory.setReadTimeout(5000);//unit is ms
        factory.setConnectTimeout(5000);//unit is ms
        return factory;
    }
}
