quartz重复执行的问题

最近用到quartz做集群,需求每隔一段时间执行一次任务。
发现在配置较短的时间间隔,比如15秒钟执行一次时,会出现,服务器启动会有多个线程(不等,有时候2个,多的时候4个,quartz线程数目用的默认的10个)重复执行该任务。
控制台信息如下:图片说明

而当我配置成1min执行一次的时候,就没有问题,不会重发执行。
主要的配置文件如下,求解,感谢感谢。

<bean id="autoRepeatRequestTask"
        class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <property name="jobClass">
            <value>com..job.AutoRequestRepeatJob</value>
        </property>
        <property name="durability" value="true" />
        <property name="requestsRecovery" value="true" />
    </bean>
    <!-- 定义触发时间 -->
    <bean id="autoRepeatRequestDoTime"
        class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail">
            <ref bean="autoRepeatRequestTask" />
        </property>
        <!-- cron表达式 -->
        <property name="cronExpression">
            <value>0 * * * * ?</value>
            <!--每分钟执行一次 -->
        </property>
    </bean>
    <!-- 总管理类 如果将lazy-init='false'那么容器启动就会执行调度程序 -->
    <bean id="startQuartz" lazy-init="false" autowire="no"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean"
        destroy-method="destroy">
        <property name="configLocation" value="classpath:quartz.properties" />
        <property name="triggers">
            <list>
                <ref bean="autoRepeatRequestDoTime" />
            </list>
        </property>
        <property name="startupDelay" value="10" />
        <property name="applicationContextSchedulerContextKey" value="applicationContextKey" />
    </bean>

执行的任务类:


@PersistJobDataAfterExecution
@DisallowConcurrentExecution // 不允许并发执行
public class AutoRequestRepeatJob extends QuartzJobBean {
    private static final Logger LOGGER = LoggerFactory.getLogger(AutoRequestRepeatJob.class);

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        System.out.println(Thread.currentThread().getName()+"------初始化了"+DateTimeUtils.getNowHHmmss());
        RequestRepeatService requestRepeatService = getApplicationContext(context).getBean(RequestRepeatService.class);
        requestRepeatService.autoRepeatRequest();

    }

    private ApplicationContext getApplicationContext(final JobExecutionContext jobexecutioncontext) {
        try {
            return (ApplicationContext) jobexecutioncontext.getScheduler().getContext().get("applicationContextKey");
        } catch (SchedulerException e) {
            LOGGER.error("jobexecutioncontext.getScheduler().getContext() error!", e);
            throw new RuntimeException(e);
        }
    }

}

或者是因为我的具体的任务写的有问题,里面用到了线程池。因为开辟的线程池没有释放? 求解求解

  private static ListeningExecutorService FixedExecutorService = MoreExecutors.listeningDecorator(Executors.newFixedThreadPool(FIXED_THREAD_NUM));
