  是这样的，客户有个需求是可以自己修改任务的间隔时间的！(这个值是设置到数据库中的)，因为SimpleTriggerBean必须设置repeatInterval属性，而这个值因为是保存在数据中的，所以我想设置两个定时任务CMSTransformCRMTrigger和ScheduleInfoActionTrigger，ScheduleInfoActionTrigger在CMSTransformCRMTrigger任务执行前触发：其目的是为CMSTransformCRMTrigger根据数据库的值设置其repeatInterval属性，配置文件如下：

    <bean id="CMSTransformCRMEngine" class="org.springframework.aop.framework.ProxyFactoryBean">
        <property name="targetSource">

ScheduleInfoAction是动态设置间隔时间的接口：

public class ScheduleInfoAction {

    private Scheduler scheduler;

    public void setTaskTimeByPreference() throws SchedulerException {
        if (isStartCMSTransformCRMTask()) {
            SimpleTriggerBean trigger = (SimpleTriggerBean) scheduler.getTrigger("ScheduleInfoActionTrigger",
                            Scheduler.DEFAULT_GROUP);
            trigger.setRepeatInterval(Long.parseLong(Application.getSystemSettingService().getPrefValue("CMSPeriod")));
            scheduler.rescheduleJob("ScheduleInfoActionTrigger",
                    Scheduler.DEFAULT_GROUP, trigger);
        } else {
            scheduler.shutdown();
        }
    }

    public boolean isStartCMSTransformCRMTask() {
        return Application.getSystemSettingService().getPrefValue("CMSPeriod") != null;
    }

    public Scheduler getScheduler() {
        return scheduler;
    }

    public void setScheduler(Scheduler scheduler) {
        this.scheduler = scheduler;
    }

}

  但是不知为和两个任务都不执行？

后面我再在程序启动时就通过ScheduleInfoAction的factoryBean

设置CMSTransformCRMTrigger其repeatInterval属性,只保留一个定时任务就可以了，

配置如下：


<bean id="ScheduleInfoAction" class="com.wisecrm.server.business.cms.ScheduleInfoAction">         
        <property name="scheduler" ref="schedulerFactory"/>     
    </bean>
    
    <bean id="ScheduleInfoActionFactory" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="CMSTransformCRMEngine"/>
        <property name="targetMethod">
             <value>run</value>
        </property>
        <property name="concurrent" value="false"/>
    </bean>
    
    <bean id="ScheduleInfoActionTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">         
        <property name="jobDetail">
            <ref bean="ScheduleInfoActionFactory"></ref>
        </property>    
        <property name="startDelay">
            <value>80000</value>
        </property>
        <property name="repeatInterval">
            <value>80000</value>
        </property>
    </bean>
    
    <bean id="schedulerFactory" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">         
        <property name="triggers">             
            <list>            
                <ref bean="ScheduleInfoActionTrigger"/>             
            </list>         
        </property>
    </bean>


但总感觉到有点笨拙，你帮忙参考下，为什么repeatInterval不能通过继承SimpleTriggerBean复写getRepeatInterval方法去设置呢？

SELECT wjbh,wjmc FROM (SELECT row_.*, rownum rownum_ FROM (select wjbh,wjmc,rownum rn from y_wjlx) row_ WHERE rownum <= #end#) WHERE rownum_ > #start#
中的select wjbh,wjmc,rownum rn from y_wjlx不会造成很大的效率问题吗？
