SSM---SpringMVC+Spring+Mybatis項目整合定時器Schedule(手動開啓任務、手動關閉任務、設置定時時間)

1. 編寫定時任務(在任務方法run()中使用service查詢數據庫)，任務類需要實現Runnable接口

public class SchedulerTask implements Runnable{
	/**
	 * DESC : 定時任務邏輯
	 * 
	 * */
	@Override
	public void run() {
		System.out.println("Schedule............");
	}

}

2.編寫開啓/設置定時時間、關閉定時任務接口

@Controller
public class TaskController {
	

	@Autowired
	private ThreadPoolTaskScheduler threadPoolTaskScheduler;

	private ScheduledFuture<?> future;

	
	
	@RequestMapping(value = "/startTask.do", method = RequestMethod.POST)
	@ResponseBody
	public String startTask(String time) throws UnsupportedEncodingException {
		stopTask(); 					//先關閉之前的定時任務					
		String cron = "*/5 * * * * ?";	//定時任務時間表達式
		//開啓定時任務
		future = threadPoolTaskScheduler.schedule(new SchedulerTask(), new CronTrigger(cron));	
		return "startTask";
	}

	
	@RequestMapping(value = "/stopTask.do", method = RequestMethod.POST)
	public String stopTask() {
		stopTimeTask();
		return "stopTask";
	}
	
	

	public void stopTimeTask() {
		if (future != null) {
			future.cancel(true);
		}
	}
}
