**1. 编写定时任务([在任务方法run()中使用service查询数据库][run_service])，任务类需要实现Runnable接口**

public class SchedulerTask implements Runnable{
    	/**
    	 * DESC : 定时任务逻辑
    	 * 
    	 * */
    	@Override
    	public void run() {
    		System.out.println("Schedule............");
    	}
    
    }

**2.编写开启/设置定时时间、关闭定时任务接口**

@Controller
    public class TaskController {
    	
    
    	@Autowired
    	private ThreadPoolTaskScheduler threadPoolTaskScheduler;
    
    	private ScheduledFuture<?> future;
    
    
    
          @Bean
          public ThreadPoolTaskScheduler threadPoolTaskScheduler() {
              return new ThreadPoolTaskScheduler();
          }
    
    	
    	
    	@RequestMapping(value = "/startTask.do", method = RequestMethod.POST)
    	@ResponseBody
    	public String startTask(String time) throws UnsupportedEncodingException {
    		stopTask(); 					//先关闭之前的定时任务					
    		String cron = "*/5 * * * * ?";	//定时任务时间表达式
    		//开启定时任务
    		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);
    		}
    	}
    }
