此 demo 主要演示了 Spring Boot 如何集成 XXL-JOB 实现分布式定时任务，并提供绕过
xxl-job-admin对定时任务的管理的方法，包括定时任务列表，触发器列表，新增定时任务，删除定时任务，停止定时任务，启动定时任务，修改定时任务，手动触发定时任务。

执行器管理 - 新增执行器
任务管理 - 新增 - 保存
任务列表的操作列，拥有以下操作：执行、启动/停止、日志、编辑、删除
执行：单次触发任务，不影响定时逻辑
启动：启动定时任务
停止：停止定时任务
日志：查看当前任务执行日志
编辑：更新定时任务
删除：删除定时任务
实际场景中，如果添加定时任务都需要手动在 xxl-job-admin 去操作，这样可能比较麻烦，用户更希望在自己的页面，添加定时任务参数、定时调度表达式，然后通过 API 的方式添加定时任务
