## 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>

#### bootstrap.yml ####

--------------------

spring:
      zipkin:
        base-url: http://localhost:9411
