如何使用spring中的定时任务

<!-- spring 定时任务 begin-->
		<dependency>
			<groupId>opensymphony</groupId>
			<artifactId>quartz-all</artifactId>
			<version>1.6.3</version>
		</dependency>
		<!-- spring 定时任务 end-->

	public class PayJob {

		public void startJob() {
			System.out.println("PayJob开始执行。。。。。。");
		}

	}

	

<!-- 支付的Job作业类 -->
	<bean id="payJobDetailBean" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject">
			<bean class="com.suning.ptoms.controller.order.PayJob" />
		</property>
		<property name="targetMethod" value="startJob" />
		<property name="concurrent" value="false" /><!-- 作业不并发调度 -->
	</bean>


	<!-- 支付的定时调度器 -->
	<bean id="payCronTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail" ref="payJobDetailBean"></property>
		<!-- 每分钟执行一次 -->
		<property name="cronExpression" value="0 0/1 * * * ?"></property>
	</bean>




	<!-- 总调度器 -->
	<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref local="payCronTriggerBean"></ref>
			</list>
		</property>
	</bean>
