无法正常停止quartz的线程

JOB是

@IocBean
public class StockJob implements Job{

	@Override
	public void execute(JobExecutionContext arg0) throws JobExecutionException {
		// TODO Auto-generated method stub
		System.out.println("任务正在执行，执行时间: " + Calendar.getInstance().getTime());
	}
	
}

Schedule是

    private void stockSchedule() throws Throwable{
    	sf = new StdSchedulerFactory();  
        // 从工厂里面拿到一个scheduler实例  
        sched = sf.getScheduler();  
        // 计算任务的开始时间，DateBuilder.evenMinuteDate方法是取下一个整数分钟  
//        Date runTime = DateBuilder.evenMinuteDate(new Date());  
        // 真正执行的任务并不是Job接口的实例，而是用反射的方式实例化的一个JobDetail实例  
        job = JobBuilder.newJob(StockJob.class).withIdentity("job1", "group1").build();  
        // 定义一个触发器，startAt方法定义了任务应当开始的时间  
//        Trigger trigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "group1").startAt(runTime).build();  
        // 定义触发时间
        CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "group1")  
                .withSchedule(CronScheduleBuilder.cronSchedule("0/5 * * * * ?")).build(); 
        // 将任务和Trigger放入scheduler  
        sched.scheduleJob(job, trigger);  
        sched.start();  
    }

在Nutz SetUp里面

	@Override
	public void destroy(NutConfig config) {
		// TODO Auto-generated method stub
		System.out.println("关闭服务");
////		//定时任务
//		MainSchedule mainSchedule=new MainSchedule();
//		mainSchedule.shutdownSchedule();
		try {
			config.getIoc().get(Scheduler.class).shutdown(true);
		} catch (Exception e) {
		}
	}

用的是tomcat8.0.9,启动服务的时候正常，也能正常运行线程，但是在关闭服务的时候，线程无法关闭
控制台报错

请问是为什么会有11个线程？然后为什么会关不掉会有内存溢出？
谢谢了

你自己new的啊, 自行关掉啊

private void stockSchedule() throws Throwable{
    	sf = new StdSchedulerFactory();  
        // 从工厂里面拿到一个scheduler实例  
        sched = sf.getScheduler();  
		//.................
		
// 在MainSetup里面

public void destroy(NutConfig config) {
        sched.shutdown(true); // 这里的sched指向stockSchedule方法那个sched
}

qq_411db427 2楼•3082天前

@wendal 我在我的MainSchedule类里面有一个

    public void shutdownSchedule() {
        if (null != sched) {  
            try {  
                sched.shutdown();  
                try {
					Thread.sleep(1000);
				} catch (InterruptedException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
            } catch (SchedulerException e) {  
                e.printStackTrace();  
            }  
        }  
    }

这样的方法，我在destroy（）里面直接调用这个方法也不行

	@Override
	public void destroy(NutConfig config) {
		// TODO Auto-generated method stub
		System.out.println("关闭服务");
////		//定时任务
		MainSchedule mainSchedule=new MainSchedule();
		mainSchedule.shutdownSchedule();
		try {
//			config.getIoc().get(Scheduler.class).shutdown(true);
		} catch (Exception e) {
		}
	}

@wendal 依然是无法关闭线程

我晕啊, new个新的然后关,那老的关吗??!!!!

		MainSchedule mainSchedule=new MainSchedule();
		mainSchedule.shutdownSchedule();

起码改成单例

public class MainSchedule {
      public static MainSchedule me; // 放在一个静态变量里面
	  public MainSchedule() {
	       me = this; // 或者用其他单例方式也行.
	  }
	  // 其他方法
}

// 然后在MainSetup里面取这个实例来调用
@Override
	public void destroy(NutConfig config) {
		MainSchedule.me.shutdownSchedule();
	}

@wendal 哦哦哦。我懂了。。谢谢大神。。我new了一个新的来管。。老的还在继续运行。。谢谢大神。。

qq_411db427 6楼•3079天前

@wendal 大神，我还有一个问题，我在job里面的execute方法里面使用dao，然后用您之前教我的

	@Inject
	protected Dao dao;
	public Dao dao() {
	    if (dao == null)
		    dao = Mvcs.getIoc().get(Dao.class);
	    return dao;
	}

程序里面用this.dao()来调用
但是在运行的时候还是会报空指针异常，请问这个需要怎么解决呢？

 dao = Mvcs.ctx().getDefaultIoc().get(Dao.class);
