Schedule存在spring-context.jar包中。
实现简单步骤:
1、配置bean.xml开启定时任务支持。
<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd "> <!-- 开启定时任务 --> <task:annotation-driven /> <context:component-scan base-package="com.jsoft.testspring" /> <context:annotation-config /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix"> <value>/WEB-INF/jsp/</value> </property> <property name="suffix"> <value>.jsp</value> </property> </bean> </beans>
代码实现:
package com.jsoft.testspring.testmvchelloworld; import java.text.SimpleDateFormat; import java.util.Date; import org.springframework.scheduling.annotation.Scheduled; import org.springframework.stereotype.Component; @Component public class ScheduleTest { @Scheduled(cron = "0/5 * * * * ?") public void schTest1() { Date date = new Date(); SimpleDateFormat sim = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String dateStr = sim.format(date); System.out.println("这是spring定时器1,每五秒执行一次,当前时间:" + dateStr); } }
注意要加@Component这类的注解。
