spring配置Quartz定时器时出现的异常如下：

spring中的配置:

<bean id="secondTimerTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
	<property name="jobDetail" ref="secondTimerJob" />  
	<property name="cronExpression" value="0 0 1 * * 2" /> 
</bean>

异常原因是： Day of month 用的是*号匹配表示的每一天，而我Day of week中又指定了哪一天所以造成了冲突（反之也会报错）。

解决办法：
如果Day of month或Day of week这2个其中一个指定的日期，那么另外一个则要用?来占位，表示不确定的。如

<property name="cronExpression" value="0 0 1 ? * 2" />
