SpringBoot 整合Quartz（集群）实现定时任务调度

如果对quartz集群原理和配置不太了解，大家可参考文章：Quartz集群原理及配置应用，这里我就不细说了

SpringBoot实现定时任务两种方式：

1、基于 spring的@Scheduled注解;

可参考文章：SpringBoot整合Quartz定时任务（基于注解方式），这种方式比较便捷，在单台服务部署情况下可使用，若部署多台机器，到了时间点，便会同时均开始这个执行定时任务（问题）。

2、使用Quartz（集群环境）实现：

2.1 Quzrtz集群的实现方式在于11张表，集群节点相互之间不通信，而是通过相同的数据库表来感知到另一节点的,因此Quartz集群依赖于数据库，必须先创建数据库表，数据表是官方提供的 ，有11张表，如下：

项目结构：

2.2 创建maven项目pom.xml添加依赖：
