0 0-15 23 * * ? 每天23:00至23:15每分钟触发一次
0 0/5 * * * ? 每隔5分钟触发一次

bean配置的顺序:
定时器的工厂bean-->cronbean-->具体实现的bean

<bean
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="cronExpReport" />
            </list>
        </property>
    </bean>

    
    <bean id="cronExpReport"
        class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail">
            <ref bean="detailBean" />
        </property>
        <property name="cronExpression">
            <value>0 0-15 23 * * ?</value>
        </property>
    </bean>

<bean id="detailBean"
        class="org.springframework.scheduling.quartz.JobDetailBean">
        <property name="jobClass">
            <value>com.bo.detailBO</value>
        </property>
        <property name="jobDataAsMap">
            <map>
                 <entry key="baseBO">
                    <ref bean="baseBO" />
                </entry>
            </map>
        </property>
</bean>
