//                开启一个定时任务，如果两天后用户没有手动关闭这次咨询，则自动关闭
                JobDataMap jobDataMap = new JobDataMap();
                jobDataMap.put("consultingId", consultingId);
                jobDataMap.put("consultationService", consultationService);
                JobDetail detail = JobBuilder.newJob(ManualCancelConsultationTask.class)
                        .withIdentity("job-" + consultingId, "group-" + consultingId)
                        .usingJobData(jobDataMap)
                        .build();
                Trigger trigger = TriggerBuilder.newTrigger()
                        .forJob(detail)
                        .withSchedule(
                                SimpleScheduleBuilder
                                        .simpleSchedule()
                                        .withIntervalInSeconds(10)
                                        .withRepeatCount(1)
                        ).build();
                scheduler.scheduleJob(detail, trigger);
                scheduler.start();

代码如上，我想让定时任务只执行一次，10秒后执行。但scheduler.start()后执行了一次，10秒后又执行了一次。
