二. 核心

1. 核心概念

任务Task(Job)
JobDetail及 Job 类
JobDetail: 任务数据
Job: 任务逻辑
JobExecutionContext: Job运行时上下文信息

public class PrintWordsJob implements Job {

}

 JobDetail jobDetail = JobBuilder.newJob(PrintWordsJob.class)
                                        .withIdentity("job1", "group1").build();

触发器Trigger
Trigger:
SimpleTrigger: 简单触发器
CronTrigger: 基于日历的作业调度

Trigger trigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "triggerGroup1")
                .startNow()//立即生效
                .withSchedule(SimpleScheduleBuilder.simpleSchedule()
                .withIntervalInSeconds(1)//每隔1s执行一次
                .repeatForever()).build();//一直执行
scheduler.scheduleJob(jobDetail, trigger);
