后台没报错，只有项目启动的时候执行一次，之后就没有执行了，定的是10秒执行一次

 SchedulerFactory sf = new StdSchedulerFactory();
        Scheduler sched = null;
        Date ft = null;
        try {
            sched = sf.getScheduler();
            JobDetail job = JobBuilder.newJob(LoginOutJob.class).withIdentity("logout", "logoutGroup").build();
            CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity("logoutTrigger", "logoutGroup")
                    .withSchedule(CronScheduleBuilder.cronSchedule("0/10 * * * * ?")).build();
            ft = sched.scheduleJob(job, trigger);                                           
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
