spring对Java的Timer类和Quartz都提供了一个抽象层，使用我们可以更方便地使用它们。
1）spring对Timer的集成
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"
default-autowire="byName">
<bean id="timer" class="org.springframework.scheduling.timer.TimerFactoryBean">
<property name="scheduledTimerTasks">
<list>
<ref local="schedule" />
</list>
</property>
</bean>
<bean id="schedule" class="org.springframework.scheduling.timer.ScheduledTimerTask">
<property name="timerTask">
<ref bean="myTask" />
</property>
<property name="delay">
<value>1000</value>
</property>
<property name="period">
<value>1000</value>
</property>
</bean>
<bean id="myTask" class="com.test.MyTask" />
</beans>
2）spring对quartz的集成
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"
default-autowire="byName">
<bean id="myTask" class="com.test.MyTask" />
<!-- jobDetail -->
<bean id="quartzJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="myTask" />
<property name="targetMethod" value="run" />
<property name="concurrent" value="false" />
</bean>
<!-- trigger -->
<bean id="quartzTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="quartzJobDetail" />
<property name="cronExpression" value="0/3 * * * * ?"/>
</bean>
<!-- schdule -->
<bean id="quertzSchdule" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="quartzTrigger" />
</list>
</property>
</bean>
</beans>
在spring容器加载配置文件中的bean后，任务调度就会开始。
