前一段时间，在工作中要使用定时器功能

1、首先web.xml中配置

<!-- 配置spring核心servlet -->
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

2、开 启定时启开 关在

spring-servlet.xml 中开启

<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:task="http://www.springframework.org/schema/task" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans   
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd    
    http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd    
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd    
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd    
    http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd">

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

	<!-- 自动扫描的包名 -->
	<context:component-scan base-package="com.zxl78585.springtask.task" />

	<bean id="myTask" class="com.zxl78585.springtask.task.MyTask"></bean>

	<task:scheduled-tasks>
		<!-- 这里表示的是每隔五秒执行一次 -->
		<task:scheduled ref="myTask" method="show" cron="*/10 * * * * ?" />
	</task:scheduled-tasks>

</beans>

 3、写自己的定时器

public class MyTask {

	public void show(){
		System.out.println(new Date().getTime());
	}
}
