Spring学习笔记 调度

1.传统的定时器调度

public class MyTimerTask extends java.util.TimerTask{
	@Override
	public void run() {
		System.out.println("Send Message....");
	}
}

<bean id = "myTimerTask" class="study.spring.schedule.MyTimerTask"/>
<bean id ="scheduledTimerTask" class="org.springframework.scheduling.timer.ScheduledTimerTask">
	<!-- 延迟多少毫秒后启动 -->
	<property name="delay" value="2000"/>
	<!-- 间隔时间  -->
	<property name="period" value="1000"/>
	<!-- 任务 -->
	<property name="myTimerTask" ref="timerTask"/>
</bean>
<bean id="timerFactoryBean" class="org.springframework.scheduling.timer.TimerFactoryBean">
	<property name="scheduledTimerTasks">
		<list>
			<ref bean="scheduledTimerTask"/>
		</list>
	</property>
</bean>

ScheduledTimerTask和TimerFactoryBean已标记为过时，在java中可以直接通过new Timer().schedule()来实现
2.Quartz调度
所需类库：
com.springsource.org.quartz-1.6.2.jar
org.springframework.aspects-3.1.0.RELEASE.jar
commons-collections.jar

public class MyQuartz extends QuartzJobBean{
	@Override
	protected void executeInternal(JobExecutionContext context)
			throws JobExecutionException {
		System.out.println("Send message....");
	}
}

<!--对任务进行包装 -->
	<bean id="jobDetailBean" class="org.springframework.scheduling.quartz.JobDetailBean"		>
		<property name="jobClass" value="study.spring.quartz.MyQuartz" />
	</bean>
	<!-- 简单触发器bean，类似定时器任务 -->
	<bean class="org.springframework.scheduling.quartz.SimpleTriggerBean"
		id="simpleTriggerBean">
		<!-- 调度的任务 -->
		<property name="jobDetail" ref="jobDetailBean"/>
		<!--首次启动延迟时间数 -->
		<property name="repeatInterval" value="1000"/>
		<!--周期 -->
		<property name="period" value="2000"/>
	</bean>
	<!--调度工厂 -->
	<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="simpleTriggerBean" />
			</list>
		</property>
	</bean>
<!--更加细腻的调度 
Cron触发器beanCronTriggerBean
org.springframework.scheduling.quartz.CronTriggerBean--> 
<!--cron 表达式（关于格式在spring in action有详细说明）-->
<property name="cronExpression">
<!-- 秒 分 时 日 月 星期 年-->
	<value>0-9,20,30 15 10 25 2 ? * </value>
</property>
