关于为什么要使用java.util.concurrent.ScheduledExecutorService代替Java.util.Timer/TimerTask，请参考：[http://blog.csdn.net/qq\_32786873/article/details/53024056][http_blog.csdn.net_qq_32786873_article_details_53024056]

方式一：使用Spring的任务调度类ScheduledExecutorTask

1.建立一个Java类，并实现Runnable接口

package com.Solin.Timer;
    
    import java.util.Date;
    
    public class StartupTask implements Runnable{
    
    	@Override
    	public void run() {
    		System.out.println(new Date()+" ScheduledExecutorTask...");
    	}
    
    }

2.Spring配置

<bean id="startupTask" class="com.Solin.Timer.StartupTask" />
    	<bean id="startupScheduledTask" class="org.springframework.scheduling.concurrent.ScheduledExecutorTask">
    		
    		<property name="delay" value="3000" />
    		
    		<property name="period" value="0" /> 
    		
    		<property name="runnable" ref="startupTask" />
    	</bean>
    	<bean id="timerFactory" class="org.springframework.scheduling.concurrent.ScheduledExecutorFactoryBean">
    		<property name="scheduledExecutorTasks">
    			<list>
    				<ref bean="startupScheduledTask" />
    				
    			</list>
    		</property>
    	</bean>

3.启动项目后，控制台会打印如下信息：

Thu Nov 03 18:36:24 CST 2016 ScheduledExecutorTask...
