corn表达式生成:http://www.pppet.net/
1.注解方式
添加命名空间
xmlns:task="http://www.springframework.org/schema/task"
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-4.0.xsd
task任务扫描注解
<task:annotation-driven/>
spring扫描位置
<context:annotation-config/>
<context:component-scan base-package="com.test"/>
定时任务
@Scheduled(cron="0/5 * * * * ? ") //每5秒执行一次
public void myTest(){
System.out.println("进入测试");
}
注意:定时器的任务方法不能有返回值(如果有返回值,spring初始化的时候会告诉你有个错误、需要设定一个proxytargetclass的某个值为true)
2.xml方式
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-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-3.1.xsd"> <!-- 定时任务 --> <bean id="venueLockerRecordJob" class="com.rdkl.qmjs.job.VenueLockerRecordJob"/> <bean id="venueLockerRecordJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <property name="targetObject" ref="venueLockerRecordJob" /> <property name="targetMethod" value="updateStatus" /> <!-- false:不允许并发执行 --> <property name="concurrent" value="false" /> </bean> <bean id="venueSettlementJobTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean"> <property name="description" value="更新储物柜租用状态" /> <property name="jobDetail" ref="venueLockerRecordJobDetail" /> <!-- 凌晨2点执行 0 0 2 * * ? --> <property name="cronExpression" value="0 0 12 * * ?" /> </bean> <!-- 定时任务配置 结束 --> <!-- schedulerFactory --> <bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref bean="venueSettlementJobTrigger" /> </list> </property> </bean> </beans>
