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()); } }
