Quartz 基本使用,Sprignboot使用Quartz

1.引入依赖

<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>2.3.1</version>
</dependency>

2.创建任务内容

public class Lizhi implements Job {
    @Autowired
    IStaffBaseService iStaffBaseService;
    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        JobDataMap jobDataMap = context.getJobDetail().getJobDataMap();
        log.info("离职审批过的人："+jobDataMap.get("staffBaseId"));
    }
}

3.启动并创建定时任务

            @Autowired
            private Scheduler scheduler;

            String jobName = "离职审批任务"+staffBase.getId();
            String suerid = staffBase.getId();
            String dodate  = map.get("lizhi_date");
            String date = "";
            try {
                date = FlowUtils.getCron(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse(dodate));
            } catch (ParseException e) {
                e.printStackTrace();
            }
            log.info("执行的时间为："+date);
            JobDetail jobDetail = JobBuilder.newJob(Lizhi.class).withIdentity(jobName).usingJobData("staffBaseId",suerid).build();
            Trigger trigger = TriggerBuilder.newTrigger().withIdentity(jobName).withSchedule(CronScheduleBuilder.cronSchedule(date)).build();
            //3、创建调度器Scheduler并执行
            Scheduler scheduler = null;
            try {
                scheduler = new StdSchedulerFactory().getScheduler();
                scheduler.scheduleJob(jobDetail, trigger);
                log.info("创建离职定时任务：["+suerid+"]ID:"+staffBase.getId());
                scheduler.start();
            } catch (SchedulerException e) {
                e.printStackTrace();
            }

4.Flowutils

    /**
     * 获取指定时间的cron表达式
     * @param date
     * @return
     */
    public static String getCron(Date date) {
        String dateFormat = "ss mm HH dd MM ? yyyy";
        SimpleDateFormat sdf = new SimpleDateFormat(dateFormat);
        String formatTimeStr = null;
        if (date != null) {
            formatTimeStr = sdf.format(date);
        }
        return formatTimeStr;
    }
