一、 构建Zipkin Server,官方推荐下载jar即可:

https://dl.bintray.com/openzipkin/maven/io/zipkin/java/zipkin-server/

java -jar zipkin-server-2.12.9-exec.jar

默认端口是9411 启动完成后访问:http://localhost:9411/

二、创建service-hi

       org.springframework.boot
                 
      
       spring-boot-starter
             
            
                
      
       org.springframework.cloud
                 
      
       spring-cloud-starter-zipkin
             
        
       
           
                
                     
       
        org.springframework.cloud
                      
       
        spring-cloud-dependencies
                      
       
        ${spring-cloud.version}
                      
       
        pom
                      
       
        import
                  
             
        
       
           
                
                     
       
        org.springframework.boot
                      
       
        spring-boot-maven-plugin
                  
             
        
    
   

application.properties

server.port=8988spring.zipkin.base-url=http://localhost:9411spring.application.name=service-hi

通过引入spring-cloud-starter-zipkin依赖和设置spring.zipkin.base-url就可以了。

接口暴露:

package com.xiaobu;import brave.sampler.Sampler;import lombok.extern.slf4j.Slf4j;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Value;import org.springframework.boot.CommandLineRunner;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.annotation.Bean;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import org.springframework.web.client.RestTemplate;/** * @author xiaobu */@SpringBootApplication@RestController@Slf4jpublic class ServiceHiApplication implements CommandLineRunner {
       public static void main(String[] args) {
           SpringApplication.run(ServiceHiApplication.class, args);    }    @Value("${server.port}")    private String port;    @Override    public void run(String... args) throws Exception {
           System.out.println("service-hi在端口： " +port+"启动完成....." );    }    @Autowired    private RestTemplate restTemplate;    @Bean    public RestTemplate getRestTemplate(){
           return new RestTemplate();    }    @GetMapping("/hi")    public String callHome(){
           log.info("calling trace service-hi  ");        return restTemplate.getForObject("http://localhost:8989/miya", String.class);    }    @GetMapping("/info")    public String info(){
           log.info("calling trace service-hi ");        return "i'm service-hi";    }    @Bean    public Sampler defaultSampler() {
           return Sampler.ALWAYS_SAMPLE;    }}

三、 创建service-miya

相同的依赖,修改下server port端口以及服务名即可

接口暴露:

package com.xiaobu;import brave.sampler.Sampler;import lombok.extern.slf4j.Slf4j;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Value;import org.springframework.boot.CommandLineRunner;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.annotation.Bean;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import org.springframework.web.client.RestTemplate;@SpringBootApplication@Slf4j@RestControllerpublic class ServiceMiyaApplication implements CommandLineRunner {
       public static void main(String[] args) {
           SpringApplication.run(ServiceMiyaApplication.class, args);    }    @Value("${server.port}")    private String port;    @Override    public void run(String... args) throws Exception {
           log.info("service-miya在端口:{} 启动完成....." ,port);    }    @RequestMapping("/hi")    public String home(){
           log.info( "hi is being called");        return "hi i'm miya!";    }    @GetMapping("/miya")    public String info(){
           log.info("info is being called");        return restTemplate.getForObject("http://localhost:8988/info",String.class);    }    @Autowired    private RestTemplate restTemplate;    @Bean    public RestTemplate getRestTemplate(){
           return new RestTemplate();    }    @Bean    public Sampler defaultSampler() {
           return Sampler.ALWAYS_SAMPLE;    }}

访问http://localhost:8989/miya 出现:

i’m service-hi
