SSM---SpringMVC+Spring+Mybatis项目整合定时器Schedule(手动开启任务、手动关闭任务、设置定时时间)-蒲公英云

SSM---SpringMVC+Spring+Mybatis项目整合定时器Schedule(手动开启任务、手动关闭任务、设置定时时间)

1. 编写定时任务(在任务方法run()中使用service查询数据库)，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);
        }
    }
}
