Spring的@schedule注解实现定时任务

SPRing配置文件：springmvc-servlet.xml中

xmlns加入

xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation中加入
     http://www.springframework.org/schema/task     http://www.springframework.org/schema/task/spring-task-3.0.xsd"
spring扫描注解的配置：即扫描base-package包下所有注解
<context:component-scan base-package="com.imwoniu.*" />
任务扫描注解
<task:executor id="executor" pool-size="5" />  <task:scheduler id="scheduler" pool-size="10" />  <task:annotation-driven executor="executor" scheduler="scheduler" />
在实现中：
	 /*每天16点38分执行一次这个方法。*/
        @Scheduled(cron = "0 38 16 * * ?")	 public void addAwardPool(){		GiftUtil.AWARD_POOL[0]=GiftUtil.AWARD_POOL[0]+10;		GiftUtil.AWARD_POOL[1]=GiftUtil.AWARD_POOL[1]+50;		GiftUtil.AWARD_POOL[2]=GiftUtil.AWARD_POOL[2]+30;				GiftUtil.writeAwardMessageToFile(GiftUtil.AWARD_POOL,GiftUtil.AWARD_COUNT);//写到文件	}
