SpringCloud sleuth 链路追踪的使用

zipkin 官网

一、下载

1.docker

docker pull openzipkin/zipkin
docker run -d -p 9411:9411 openzipkin/zipkin
访问地址：http://localhost:9411
注意：localhost 为你的实际ip

2.windows

二.启动依赖

 <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-sleuth</artifactId>

    </dependency>

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

SpringCloud配置文件中设置：

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

三.访问微服务

http://localhost:8080/jobHunting/listJobHunting/sendEmail
http://localhost:7777/auth-service/user/insertGoodsByFeign 此接口是gateway–>auth-service +openfeign —>GoodsService

四.访问zipkin的UI界面，观察效果

五.ZipKin数据持久化

zipkin 持久化建表sql地址

docker  run --name zipkin -d  -p 9412:9411 -e MYSQL_USER=root -e MYSQL_PASS=123456 -e MYSQL_HOST=192.168.170.130 -e STORAGE_TYPE=mysql -e MYSQL_DB=zipkin -e MYSQL_TCP_PORT=3306 openzipkin/zipkin:2.21.7
