ListByDayTimerTask代码会执行2次

org.springframework.scheduling.timer.ScheduledTimerTask
如果你用spring，那么你不需要写Timer类了，在schedulingContext-timer
.xml中加入下面的内容就可以了：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
<bean id="timer" class="org.springframework.scheduling.timer.TimerFactoryBean">
<property name="scheduledTimerTasks">
<list>
<ref local="MyTimeTask1"/>
</list>
</property>
</bean>

<bean id="MyTimeTask" class="com.qq.timer.ListByDayTimerTask"/>

<bean id="MyTimeTask1" class="org.springframework.scheduling.timer.ScheduledTimerTask">
<property name="timerTask">
<ref bean="MyTimeTask"/>
</property>
<property name="delay">
<value>10000</value>
</property>
<property name="period">
<value>86400000</value>
</property>
</bean>
</beans>
