自触发定时任务，主要在spring容器里面配置组件，调度工厂、触发器、任务等等，下面以web应用常见的日志清理为例

1、设置触发任务

<!-- 日志清理任务 -->
	<bean id="scheduledDelLogTask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject" ref="delLogTask"></property>
		<property name="targetMethod" value="delLog"></property>
		<property name="concurrent" value="false"></property>
	</bean>

2、设置触发器

<!-- 日志清理，每月1日零点启动 --> 
	<bean id="deleteLogTaskTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail" ref="scheduledDelLogTask" />
		<property name="cronExpression" value="0 0 0 1 * ?"/>
	</bean>

3、设置调度工厂

<!-- 任务调度 -->
	<bean id="schedulerFactory" class= "org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="deleteLogTaskTrigger"/>
			</list>
		</property>
	</bean>

触发任务的targetObject,对应后台执行代码类，Method对应执行方法

@Component("delLogTask")
public class DelLogTask {	
    public void delLog(){
    	log.info("开始清理操作日志定时任务！-");
	}
}
