前言：将springboot升级至2.0后，发现zipkin2使用mysql做日志存储出错，现将解决过程做个笔记。
注：2.0之后官方不再建议自定义zipkin，建议使用官方提供的zipkin.jar包，至于下载地址去百度吧。

建立zipkin-server项目

• application.yml

spring:
  application:
    name: microservice-zipkin
  sleuth:
    enabled: false

management:

• 启动类

@SpringBootApplication
@EnableZipkinServer
public class MicroserviceZipkinApplication {

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

    @Bean
    public MySQLStorage mySQLStorage(@Qualifier("druidDatasource") DataSource dataSource) {
        return MySQLStorage.newBuilder().datasource(dataSource).executor(Runnable::run).build();
    }
}

• 调用客户端可以看见zipkin-server
