springboot zipkin调用链

一.服务端(最新版本官方不建议自己写服务端,建议直接使用编译好的jar，通过启动参数来配置)

2.yaml文件配置

spring:
  application:
    name: zipkin-server
server:
  port: 9411
           

3.启动类

SpringBootApplication
@EnableZipkinServer
public class Application {
    public static void main(String[] args) {
        SpringApplication springApplication=new SpringApplication(Application.class);
        springApplication.run(args);
    }
}
           

 4.验证

输入：localhost:9411

2. yml文件

server:
  port: 8080
spring:
  application:
    name: eureka-client
  zipkin:
    base-url: http://localhost:9411
  sleuth:
    trace-id128: true
    sampler:
      percentage: 1
#健康检查
management:
  security:
    enabled: false
endpoints:
  actuator:
    enabled: true
  health:
    sensitive: true
           

3.需要注意点：需要配置http请求相关的bean

@Component
public class HttpConfig {
    @Bean
    public RestTemplate restTemplate(){
        return  new RestTemplate();
    }
}
           

 4.测试

@RequestMapping("hello")
    public String hello() throws InterruptedException {
        Thread.sleep(3000L);
        String s=restTemplate.getForEntity("http://www.baidu.com",String.class).getBody();
        System.out.println(s);
        Thread.sleep(1000L);
        return restTemplate.getForEntity("http://www.baidu.com",String.class).getBody();
    }
