一、该问题的重现步骤是什么？

1. xxl-job 引入模块 启动报错 Cannot load driver class: com.mysql.cj.jdbc.Driver


二、你期待的结果是什么？实际看到的又是什么？

启动不报错, 不采用跨平台http任务, 就是要引用模块

三、你正在使用的是什么产品，什么版本？在什么操作系统上？


四、请提供详细的错误堆栈信息，这很重要。

    配置文件增加：

    spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: ${gecco.datasource.dev.url}
    username: ${gecco.datasource.dev.username}
    password: ${gecco.datasource.dev.password}

    pom依赖增加：

    <!-- mybatis-starter：mybatis + mybatis-spring + tomcat-jdbc（default） -->
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>${mybatis-spring-boot-starter.version}</version>
    </dependency>
    <!-- mysql -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>

    最好不要引其他项目api，可以使用http方式调用其他服务api实现定时任务
