SpringCloud：Zipkin链路追踪，并将数据写入mysql

1.zipkin server

1.1.新建Springboot项目，zinkin

1.2.添加依赖

        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-server</artifactId>
        </dependency>
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-autoconfigure-ui</artifactId>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-autoconfigure-storage-mysql</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-storage-mysql</artifactId>
            <version>2.4.9</version>
        </dependency>    

 1.3.修改配置文件

zipkin:
  storage:
    type: mysql

spring:
  datasource:
    schema: classpath*:sql/mysql.sql
    url: jdbc:mysql://127.0.0.1:3306/altair_tmp?useUnicode=true&characterEncoding=utf8&autoReconnect=true
    username: root
    password: 123456
    # Switch this on to create the schema on startup:
#    initialize: true
#    continueOnError: true
  sleuth:
    enabled: false


server:
  port: 9944

eureka:
  client:
    service-url:
      defaultZone: http://th-blog.cn:7000/eureka/

1.4.主启动类

package com.chinawayltd.altair.zipkin;

import org.apache.tomcat.jdbc.pool.DataSource;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.Bean;
import zipkin.server.internal.EnableZipkinServer;
import zipkin.storage.mysql.MySQLStorage;


@SpringBootApplication
@EnableEurekaClient
@EnableZipkinServer
public class ZipkinApplication {

    public static void main(String[] args) {
        SpringApplication.run(ZipkinApplication.class, args);
    }
    @Bean
    public MySQLStorage mySQLStorage(DataSource datasource) {
        return MySQLStorage.builder().datasource(datasource).executor(Runnable::run).build();
    }
}

1.5.新建表

2.zipkin client

2.1.添加依赖
