Springboot 整合 SpringCloud组件-ZipKin &Sleuth 服务链路追踪 (五)

spring-boot-starter-parent

2.1.4.RELEASE

com.cloud

zipkin-server

0.0.1-SNAPSHOT

zipkin-server

Demo project for Spring Boot

<java.version>1.8</java.version>

org.springframework.boot

spring-boot-starter

io.zipkin.java

zipkin-server

2.11.8

io.zipkin.java

zipkin-autoconfigure-ui

org.springframework.cloud

spring-cloud-starter-netflix-eureka-server

2.0.0.RELEASE

org.springframework.boot

spring-boot-starter-test

test

org.springframework.boot

spring-boot-maven-plugin

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：

org.springframework.cloud

spring-cloud-starter-sleuth

2.0.0.RELEASE

org.springframework.cloud

spring-cloud-starter-zipkin

2.0.0.RELEASE

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%

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
