Spring-@Scheduled

@Scheduled：定时任务的注解

定时任务的配置：

1.xml配置

添加task的xml的命名空间

xmlns:task="http://www.springframework.org/schema/task"   

http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.1.xsd  

2.启用注解驱动的定时任务

<task:annotation-drivenscheduler="threadPoolTaskScheduler"/>

3.配置定时任务的线程池（如果不配线程池，默认定时任务为单线程）

<beanid="threadPoolTaskScheduler"class="org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler">

<propertyname="poolSize"value="16"/>

<propertyname="threadNamePrefix"value="taskScheduler_"/>

<propertyname="awaitTerminationSeconds"value="10"/>

</bean>

代码：

packagecom.caocao.web.job;

importorg.slf4j.Logger;

importorg.slf4j.LoggerFactory;

importorg.springframework.scheduling.annotation.Scheduled;

importorg.springframework.stereotype.Component;
