Quartz配置数据库+springboot

//1.创建触发器
CronTrigger cronTrigger1 = TriggerBuilder.newTrigger()
        .withIdentity(jobName,jobGroup)
        .withSchedule(CronScheduleBuilder.cronSchedule(cron))
        .build();
//2.创建jobDetail
//反射获取类对象的三种方式：类.class、 Class.forName(类路径)、对象.getClass()
JobDetail jobDetail = JobBuilder.newJob((Class<? extends Job>) Class.forName(jobName))
        .withIdentity(jobName, jobGroup)
        .build();
//3.将触发器和jobDetail加入到调度器中
scheduler.scheduleJob(jobDetail,cronTrigger1);
//启动
