java-在方法开始时启动固定的延迟计划,在方法完成时停止

我有一个Spring Boot Web应用程序.

我想在方法启动时启动fixedDelayed计划作业.当someMethod方法完成时,停止计划的作业.我阅读了文档,但我不明白该怎么做.我想在someMethod仍在工作时每隔30秒将dbing到db.

这是伪代码.有人有主意吗？

public void someMethod() {

    //Start scheduledLogger() to work every 30 seconds

    //...
    //Do something taking long time

    //Stop scheduledLogger() job
}

private void scheduledLogger() {
    //Log to database
}

解决方法:

您可以执行以下操作：

public void someMethod() 
   {
       //Start scheduledLogger() to work every 30 seconds
       TimerTask tasknew = new TimerTask(){
            @Override
            public void run()
            {
                scheduledLogger();

            }
        };
       Timer timer = new Timer();

       // scheduling the task
       timer.scheduleAtFixedRate(tasknew, new Date(), 3000);      

        //Do something taking long time
        try
        {
            Thread.sleep(20000);
        } catch (InterruptedException e)
        {
            e.printStackTrace();
        }
        //Stop scheduledLogger() job
        // terminating the timer
        timer.cancel();
    }

    private void scheduledLogger() {
        //Log to database
        System.out.println("Log to database at "+new Date());
    }
