在SpringCloud中使用Sleuth+ZipKin

软件版本

SpringBoot

2.1.4.RELEASE

SpringCloud

Greenwich.SR1

zipkin

2.12.2

搭建ZipKin服务

在Pom文件中引入相关依赖

    1.8
    2.12.2


    io.zipkin.java
    zipkin-server
    ${zipkin.version}


    io.zipkin.java
    zipkin-autoconfigure-ui
    ${zipkin.version}


    io.zipkin.java
    zipkin-autoconfigure-storage-mysql
    ${zipkin.version}

Java代码

@SpringBootApplication
@EnableZipkinServer
public class ZipkinServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ZipkinServerApplication.class, args);
    }
}

服务配置

在application.yml添加zipkin配置，指定追踪数据保存在mysql中。

server:
  port: 9441
spring:
  application:
    name: zipkin-server
zipkin:
  storage:
    type: mysql
    mysql:
      jdbcUrl: jdbc:mysql://localhost:3306/zipkin?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=GMT%2B8
      username: root
      password: abcdefg
management:
  metrics:
    web:
      server:
        auto-time-requests: false #不加会启动报错

因为将追踪数据都保存在MySQL中，所以需要数据建表语句。SQL脚本在zipkin-storatge-mysql-v1.2.12.1.jar的mysql.sql中，复制即可。

启动及访问

启动ZipkinServerApplication后，可通过地址

http://localhost:9441

进行访问。

在微服务中使用Sleuth

微服务中引入相关依赖

    org.springframework.cloud
    spring-cloud-starter-sleuth


    org.springframework.cloud
    spring-cloud-sleuth-zipkin

服务配置

在application.xml中设置Sleuth的相关参数

spring:
  application:
    name: sleuth-demo
  zipkin:
    base-url: http://localhost:9441
  sleuth:
    sampler:
      probability: 1.0 

1. spring.zipkin: 指定zipkin服务的地址
2. spring.sleuth.sampler.probability: 指定采样率，默认是0.1，修改为1.0，即全部采样。

启动微服务

启动微服务后并发起请求后，即可在zipKin中看到追踪数据。

PS:zipkin的建表语句
