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/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());
}
}
