YML配置

spring:
  quartz:
    job-store-type: JDBC
    jdbc:
      initialize-schema: ALWAYS #NEVER ，ALWAYS会自动初始化数据库
    properties:
      org:
        quartz:
          overwrite-existing-jobs: true
          scheduler:
            instanceName: clusteredScheduler #调度标识名 集群中每一个实例都必须使用相同的名称
            instanceId: AUTO #ID设置为自动获取 每一个必须不同
          jobStore:
            class: org.quartz.impl.jdbcjobstore.JobStoreTX #数据保存方式为持久化

固定任务

@Configuration
public class HelloJobConfig {

   //quartz数据库设置连接池
    @Bean
    @QuartzDataSource//quartz专用注解
    @ConfigurationProperties(prefix = "spring.quartz.data-source")
    public DataSource quartzDataSource(){
        return new HikariDataSource();
    }

    @Bean
    public JobDetail helloJobDetail() {
        return JobBuilder.newJob(HelloJob.class)
                .withIdentity("jobDetailName", "jobDetailGroup")
                .usingJobData("userName", "zhangsan")//参数
                .storeDurably()
                .build();
    }

    @Bean
    public Trigger helloJobTrigger()
    {
        //每隔5秒执行一次
        CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule("0/5 * * * * ?");
        //创建触发器
        Trigger trigger = TriggerBuilder.newTrigger()
                .forJob(helloJobDetail())//关联上述的JobDetail
                .withIdentity("triggerName","triggerGroup")//给Trigger起个名字
                .withSchedule(cronScheduleBuilder)
                .build();
        return trigger;
    }
}

通过接口添加删除更新自定义任务的触发器

(以用户自定义闹钟模拟)

1) 添加闹钟

   public void addTime(AddFoodRemindDto dto) throws SchedulerException {
        JobDataMap jobDataMap = new JobDataMap();
        jobDataMap.put("deviceId", dto.getDeviceId());
        jobDataMap.put("time", dto.getTime());
        jobDataMap.put("userId", dto.getUserId());

        String jobName = dto.getUserId() + "_" + dto.getTime();
        String jobGroup = FoodRemindJob.NAME_SPACE;

        TriggerKey triggerKey = TriggerKey.triggerKey(jobName, jobGroup);

        Trigger checkExist = scheduler.getTrigger(triggerKey);
        if (checkExist == null) {
            JobDetail jobDetail = JobBuilder.newJob(FoodRemindJob.class)
                    .requestRecovery(false)
                    .usingJobData(jobDataMap)
                    .withIdentity(jobName, jobGroup)
                    .storeDurably(true)
                    .build();
            CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule(getCronByTime(dto.getTime()))
                    .withMisfireHandlingInstructionDoNothing();
            CronTrigger trigger = TriggerBuilder.newTrigger()
                    .withIdentity(jobName, jobGroup)
                    .withSchedule(cronScheduleBuilder)
                    .build();
            scheduler.scheduleJob(jobDetail, trigger);
        }
    }

  private String getCronByTime(String time) {
        String model = "0 {0} {1} * * ?";
        String[] split = time.split(":");
        return MessageFormat.format(model, split[1], split[0]);
   }

2) 删除闹钟

   public void deleteTime(DeleteFoodRemindDto dto) throws SchedulerException {
        String jobName = dto.getUserId() + "_" + dto.getTime();
        String jobGroup = FoodRemindJob.NAME_SPACE;

        TriggerKey triggerKey = TriggerKey.triggerKey(jobName, jobGroup);
        Trigger checkExist = scheduler.getTrigger(triggerKey);
        if (checkExist != null) {
            scheduler.unscheduleJob(triggerKey);
            scheduler.deleteJob(JobKey.jobKey(jobName, jobGroup));
        }
    }

3）工具方法

   //创建job
   public void createJob(Scheduler scheduler, Class<? extends Job> jobClass, String jobName, String jobGroup, String cron, Map<String, Object> param) throws SchedulerException {
        JobDetail jobDetail = JobBuilder.newJob(jobClass)
                .withIdentity(jobName, jobGroup)
                .build();
        if (param != null && !param.isEmpty()) {
            param.forEach((key, value) -> jobDetail.getJobDataMap().put(key, value));
        }
        CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cron);
        CronTrigger build = TriggerBuilder.newTrigger()
                .withIdentity(jobName, jobGroup).withSchedule(scheduleBuilder)
                .build();
        scheduler.scheduleJob(jobDetail, build);
    }

    //刷新job
    public void refreshJob(Scheduler scheduler, String jobName, String jobGroup, String cron) throws SchedulerException {
        TriggerKey triggerKey = TriggerKey.triggerKey(jobName, jobGroup);
        CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cron);
        CronTrigger build = TriggerBuilder.newTrigger()
                .withIdentity(jobName, jobGroup).withSchedule(scheduleBuilder)
                .build();
        scheduler.rescheduleJob(triggerKey, build);
    }

    //恢复job
    public void resumeJob(Scheduler scheduler, String jobName, String jobGroup) throws SchedulerException {
        scheduler.resumeJob(JobKey.jobKey(jobName, jobGroup));
    }

    //暂停job
    public void pauseJob(Scheduler scheduler, String jobName, String jobGroup) throws SchedulerException {
        scheduler.pauseJob(JobKey.jobKey(jobName, jobGroup));
    }

    //删除job
    public void deleteJob(Scheduler scheduler, String jobName, String jobGroup) throws SchedulerException {
        scheduler.unscheduleJob(TriggerKey.triggerKey(jobName, jobGroup));
        scheduler.deleteJob(JobKey.jobKey(jobName, jobGroup));
    }
