Spring定时任务

配置文件配置

<!--计划任务配置，用 @Service @Lazy(false)标注类，用@Scheduled(cron = "0 0 2 * * ?")标注方法-->

    <task:executor id="executor" pool-size="10"/> <task:scheduler id="scheduler" pool-size="10"/>

    <task:annotation-driven scheduler="scheduler" executor="executor" proxy-target-class="true"/>

启动tomcat即可
