首先在spring中配置:

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop "
       xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
        xmlns:task="http://www.springframework.org/schema/task"
	xsi:schemaLocation="http://www.springframework.org/schema/beans  
            http://www.springframework.org/schema/beans/spring-beans-3.1.xsd  
            http://www.springframework.org/schema/context   
            http://www.springframework.org/schema/context/spring-context-3.1.xsd  
            http://www.springframework.org/schema/mvc  
            http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
            http://www.springframework.org/schema/tx
            http://www.springframework.org/schema/tx/spring-tx.xsd
	    http://www.springframework.org/schema/aop  
	    http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
            http://www.springframework.org/schema/task  
	    http://www.springframework.org/schema/task/spring-task-3.1.xsd">

	<!-- 定時器開關 開始 -->
	<task:annotation-driven />
</beans>
 

import org.springframework.context.annotation.Lazy;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
@Lazy(false)
public class SpringTaskController {
    /**
     * @throws Exception
     */
    @Scheduled(cron = "0/10 * *  * * ? ")
    public void task() throws Exception {
        System.out.println("我執行了...");
    }
}
