      是這樣的，客戶有個需求是可以自己修改任務(wù)的間隔時間的！(這個值是設(shè)置到數(shù)據(jù)庫中的)，因為SimpleTriggerBean必須設(shè)置repeatInterval屬性，而這個值因為是保存在數(shù)據(jù)中的，所以我想設(shè)置兩個定時任務(wù)CMSTransformCRMTrigger和ScheduleInfoActionTrigger，ScheduleInfoActionTrigger在CMSTransformCRMTrigger任務(wù)執(zhí)行前觸發(fā)：其目的是為CMSTransformCRMTrigger根據(jù)數(shù)據(jù)庫的值設(shè)置其repeatInterval屬性，配置文件如下：

    

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

                <property name="targetSource">

                    </list>         

                </property>

            </bean>
    

    

    ScheduleInfoAction是動態(tài)設(shè)置間隔時間的接口： 
    

    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;

        }    

    

    }
    

      但是不知為和兩個任務(wù)都不執(zhí)行？
    

    后面我再在程序啟動時就通過ScheduleInfoAction的factoryBean
    

    設(shè)置CMSTransformCRMTrigger其repeatInterval屬性,只保留一個定時任務(wù)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>
    

    

    但總感覺到有點笨拙，你幫忙參考下，為什么repeatInterval不能通過繼承SimpleTriggerBean復(fù)寫getRepeatInterval方法去設(shè)置呢？
