一、添加服务跟踪微服务项目zipkin-server

父pom添加zipkin相关依赖

</project>

本身pom文件依赖

<dependency>
   <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--zipkin中包含spring-cloud-starter-sleuth,无需再次引入-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>
<dependency>
    <groupId>io.zipkin.java</groupId>
    <artifactId>zipkin-server</artifactId>
</dependency>
<dependency>
    <groupId>io.zipkin.java</groupId>
    <artifactId>zipkin-autoconfigure-ui</artifactId>
</dependency>

配置文件

server:
  port: 9411
spring:
  application:
    name: zipkin-server
eureka:
  instance:
    hostname: localhost
  client:
    serviceUrl:
      defaultZone: http://localhost:8000/eureka/
management:
  metrics:
    web:
      server:
        auto-time-requests: false

启动类添加@EnableZipkinServer

package com.lxt.zipkin;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import zipkin2.server.internal.EnableZipkinServer;

@SpringBootApplication
@EnableZipkinServer
public class ZipkinServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ZipkinServerApplication.class, args);
    }

}

二、改造service-consumer、service-provider和zuul

分别添加依赖

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zipkin</artifactId>
        </dependency>

配置文件分别添加

  #重点
  zipkin:
    #        base-url:当你设置sleuth-cli收集信息后通过http传输到zinkin-server时，需要在这里配置
    base-url: http://localhost:9411
    enabled: true
  sleuth:
    sampler:
      #收集追踪信息的比率，如果是0.1则表示只记录10%的追踪数据，如果要全部追踪，设置为1（实际场景不推荐，因为会造成不小的性能消耗）
      probability: 1.0

注意：添加完毕依赖之后，刷新maven。

运行测试

• 分别启动注册中心、网关、服务跟踪、服务提供和服务消费者
• 访问服务跟踪界面http://localhost:9411
  
• 浏览器访问http://localhost:8006/spring-cloud-pr/hello/1?token=2,查看服务跟踪界面
