一、构建项目

用到的依赖直接看pom.xml的注释吧

<?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>

        <relativePath /> <!-- lookup parent from repository -->

    <build>
        <plugins>
            <plugin>

                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>


</project>

二、配置文件

因为已经有了配置中心，所以大多数配置现在开始放在SVN下，先展示一下项目内的配置文件

application.yml

只指定一个运行端口

server:  
  port: 9003

现在多引用了一个

bootstrap.yml

bootstrap.yml 是先于 application.yml 加载的，所以连接配置中心的参数需要在bootstrap.yml 设置

spring: 
  cloud: 
    config:
      uri: http://10.180.206.254:8999/ 
      profile: dev
      name: cloud-zipkin

 uri 设置的就是配置中心的地址

profile 设置版本，开发/测试/验收/生产

name 配置文件名

svn下的配置文件配置: cloud-zipkin-dev.yml

#Application name  
spring:  
  application:  
    name: cloud-zipkin
    
#注册中心      
eureka:
  client:   
    serviceUrl:
      defaultZone: http://10.180.206.254:9000/eureka/
  instance:
    ip-address: 10.180.206.254
    prefer-ip-address: true
    instance-id: ${eureka.instance.ip-address}:${server.port}

三、开启服务

package cnex.cloud.zipkin;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import zipkin.server.EnableZipkinServer;


@SpringBootApplication
@EnableZipkinServer //开启链路追踪
public class CloudZipkinApplication {

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

 

四、客户端
