注意点：

< !-- 定时器开关 开始--><task:annotation-driven/>< !-- 定时器开关 结束-->

a)、需要在xmlns里面加入：xmlns:task="http://www.springframework.org/schema/task"b)、在xsi:schemaLocation中加入http://www.springframework.org/schema/taskhttp://www.springframework.org/schema/task/spring-task-3.0.xsd

<!-- 加载应用组件 --><context:component-scan base-package="com.newyulong.spring.scheduling" />

import org.springframework.scheduling.annotation.Scheduled;import org.springframework.stereotype.Component;@Componentpublic class AnnotationQuartz {@Scheduled(cron="0 0/2 * * * ?")public void test() {System.out.println("AnnotationQuartz Testing...");}}
