SpringBoot 动态定时任务 基于 ScheduledTaskRegistrar

@Configuration
@EnableScheduling
public class MySchedulingConfig implements SchedulingConfigurer {

    public static ScheduledTaskRegistrar static_scheduledTaskRegistrar;

    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        DynamicSchedulingConfig.static_scheduledTaskRegistrar = taskRegistrar;

        ScheduledThreadPoolExecutor scheduledThreadPoolExecutor = new ScheduledThreadPoolExecutor(1);
        scheduledThreadPoolExecutor.setRemoveOnCancelPolicy(true);
        taskRegistrar.setScheduler(scheduledThreadPoolExecutor);
    }
}

public class MyConfigServiceImpl 
    ScheduledTask resetRoomTask = null;

    @Override
    public void resetScheduler() {
        ScheduledTaskRegistrar taskRegistrar = DynamicSchedulingConfig.static_scheduledTaskRegistrar;

        if (null != resetRoomTask) resetRoomTask.cancel(); // 结合 setRemoveOnCancelPolicy , 取消就会移除 Task 
        String strRoomResetTime = configApi.getConfigValueByKey(ECG_ROOM_RESET_TIME_KEY);
        LocalTime roomResetTime = Utils.parseTime(strRoomResetTime);
        String roomResetCronExpression = String.format("0 %d %d  * * ?", roomResetTime.getMinute(), roomResetTime.getHour());

        resetRoomTask = taskRegistrar.scheduleCronTask(new CronTask(() -> {
            roomService.resetRoom();
        }, roomResetCronExpression));

        taskRegistrar.afterPropertiesSet();
    }

}
