如何使用 MySQL 配置 Spring Cloud Zipkin Server 以实现持久性？

Question

Spring Boot/Cloud Zipkin 服务器（可能是 Zipkin Stream 服务器）需要哪些确切的依赖项和 application.yml 配置才能使用 MySQL 持久化跟踪数据？

Answer 1

官方文档很有帮助，但我认为它并没有明确包含所有依赖项（至少到目前为止）。我必须对样本进行一些额外的研究，才能将所有必需的依赖项和配置放在一起。我想分享它，因为我相信它可能对其他人有所帮助。

Spring Boot 版本： 1.4.0.RELEASE

Spring Cloud 版： Brixton.SR4

POM：

    ...
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>
    <dependency>
        <groupId>io.zipkin.java</groupId>

    </dependency>
    <dependency>
        <groupId>io.zipkin.java</groupId>

    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>

    </dependency>
   ...
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>

                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

Java：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import zipkin.server.EnableZipkinServer;

@SpringBootApplication
@EnableZipkinServer
public class ZipkinServerApplication {

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

application.yml：

spring:
  datasource:
    schema: classpath:/mysql.sql
    url: jdbc:mysql://localhost:3306/zipkin?autoReconnect=true
    username: root
    password: admin
    driver-class-name: com.mysql.jdbc.Driver
    initialize: true
    continue-on-error: true
  sleuth:
    enabled: false
zipkin:
  storage:
    type: mysql
