ZipKin 服务端

pom.xml

添加

io.zipkin.java:zipkin

、

io.zipkin.java:zipkin-server

、

io.zipkin.java:zipkin-autoconfigure-ui

三个依赖

<dependency>
    <groupId>io.zipkin.java</groupId>
    <artifactId>zipkin</artifactId>
    <version>2.10.1</version>
</dependency>
<dependency>
    <groupId>io.zipkin.java</groupId>
    <artifactId>zipkin-server</artifactId>
    <version>2.10.1</version>
</dependency>
<dependency>
    <groupId>io.zipkin.java</groupId>
    <artifactId>zipkin-autoconfigure-ui</artifactId>
    <version>2.10.1</version>
</dependency>
           

Application

通过

@EnableZipkinServer

注解开启 ZipKin Server 功能

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import zipkin.server.internal.EnableZipkinServer;

@SpringBootApplication
@EnableEurekaClient
@EnableZipkinServer
public class ZipKinApplication {
    public static void main(String[] args) {
        SpringApplication.run(ZipKinApplication.class, args);
    }
}
           

bootstrap.yml

设置端口号为：

9411

，该端口号为 ZipKin Server 的默认端口号

spring:
  application:
    name: hello-spring-cloud-zipkin

server:
  port: 9411
      
management:
  metrics:
    web:
      server:
        auto-time-requests: false
           

ZipKin 客户端

pom.xml

在所有需要被追踪的项目，添加

spring-cloud-starter-zipkin

依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zipkin</artifactId>
    <version>2.10.1</version>
</dependency>
