已经解决了，算是一下临时方案，哪位大神有更好的方法可以交流一下，代码如下：

    Properties props = new Properties();
    props.put(StdSchedulerFactory.PROP_THREAD_POOL_CLASS,
            "org.quartz.simpl.SimpleThreadPool");
    props.put("org.quartz.threadPool.threadCount", "50");       //任务线程个数

    StdSchedulerFactory factory = new StdSchedulerFactory();
    factory.initialize(props);
    Scheduler scheduler = factory.getScheduler();

【spring+quartz框架】scheduler.reschedulejob后执行了多次: 关于spring+quartz框架配置多线程调度任务，小弟有一事一直没搞明白一、quartz.properties中配置： #=============================================================== #Configure Main Scheduler Properties #=============================================================== org.quartz.scheduler.instanceName = QuartzScheduler org.quartz.scheduler.instanceId = AUTO #=============================================================== #Configure ThreadPool #=============================================================== org.quartz.threadPool.threadCount = 8 org.quartz.threadPool.threadPriority = 5 org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool #=============================================================== #Configure JobStore #=============================================================== org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore org.quartz.jobStore.misfireThreshold = 60000 二、XML配置文件中配置了jobDetail： <bean id="monitorSMSJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <property name="targetObject" ref="server"/> <property name="targetMethod" value="monitorSMS"/> <property name="concurrent" value="true"/> </bean> <bean id="monitorSMSCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail" ref="monitorSMSJobDetail"/> <property name="cronExpression"> <value>0/15 * * * * ?</value> </property> </bean> 三、实现类调度方法 public void monitorSMS() { //scheduler.rescheduleJob(monitorSMSCronTrigger.getName(), Scheduler.DEFAULT_GROUP, monitorSMSCronTrigger); System.out.println("enter.."); } 问题是：因配置了15秒执行一次调度，如果屏蔽掉scheduler.rescheduleJob这行代码，则每次是一个线程执行，如15:30:00 work_1执行,15:30:15 work_2执行,以此类推；如果不屏蔽，则每次8个线程并发执行，且每个线程执行N多次(N无规律，几十次到上百次吧) 求教大神，1 这是什么原因？ 2 如果想让8个线程每次执行一遍应该如何做？

" + new Date()); (更改前) ------>>>>>>>(更改后) System.out.println("in the UpdateFellingCount !!! " + new Date() + "!!!!"); 然后重新部署应用,清空tomcat的work目录,重启Eclipse, 结果还是每10秒执行一次，console内容如下: in the UpdateFellingCount !!! Wed Jul 15 15:35:00 CST 2009 in the UpdateFellingCount !!!
