导入自定义quartz.properties文件，因为quartz默认使用的是c3p0数据库连接池，我们要使用Druid

自定义的业务表
– 注意：job_name存放的任务类的全路径，在quartz中通过jobName和jobGroup来确定trigger的唯一性，所以这两列为联合唯一索引

<span style="color: #000000;">create table t_schedule_trigger
(
  id int primary key auto_increment,                                -- ID

  unique index(job_name,job_group)

-- 额外添加到任务中的参数
