接下来开始：
我们创建一个springboot项目，起名zipkin-server：
pom.xml：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.4.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.cloud</groupId>
<artifactId>zipkin-server</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>zipkin-server</name>
<description>Demo project for Spring Boot</description>
<properties>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>io.zipkin.java</groupId>
<artifactId>zipkin-server</artifactId>
<version>2.11.8</version>
</dependency>
<dependency>
<groupId>io.zipkin.java</groupId>
<artifactId>zipkin-autoconfigure-ui</artifactId>

</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
然后是application.yml：
server:
port: 9411
spring:
application:
name: zipkin-server
management:
metrics:
web:
server:
auto-time-requests: false
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
instance:
preferIpAddress: true
instance-id: ${spring.cloud.client.ip-address}:${server.port}
到这里，其实ZipKin Server这一段我们已经完成了。
我们可以将项目跑起来（记得前提eureka注册中心是正常运行的，我们有做注册），访问?[http://localhost:9411/](()? :
ZipKin服务端是正常部署运行了，那么我们需要在各个微服务上也整合这个组件，这样才能将微服务与ZipKin Server互通。
我们在网关服务，gateway的pom.xml导入依赖：
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-sleuth</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-zipkin</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>
在application.yml上添加相关的配置项后：
server:
port: 8081
spring:
application:
name: gateway-service
zipkin:
base-url: http://localhost:9411
sender:
type: web
sleuth:
sampler:
#采样100%
probability: 1.0
cloud:
gateway:
discovery:
locator:
enabled: false
#开启小写验证，默认feign根据服务名查找都是用的全大写
lowerCaseServiceId: true
routes:
- id: client-test
