1.spring-listener：

a)

import javax.servlet.ServletContextEvent;

import javax.servlet.ServletContextListener;

public class ServletImpl implements ServletContextListener {

@Override

public void contextInitialized(ServletContextEvent sce) {

// TODO Auto-generated method stub

System.out.println("web启动的时候调用此类********************************************************");

}

@Override

public void contextDestroyed(ServletContextEvent sce) {

// TODO Auto-generated method stub

System.out.println("webdestroy的时候调用此类********************************************************");

}

}

b)web.xml配置

<!-- 自定义监听器 -->

<listener>

<listener-class>com.servlet.impl.ServletImpl</listener-class>

</listener>

经过上边简单的两部操作，即可实现web容器启动时候执行某个动作。

2.spring-task

a)task.class,红色标记都是必须的。

import org.springframework.scheduling.annotation.EnableScheduling;

import org.springframework.scheduling.annotation.Scheduled;

import org.springframework.stereotype.Component;

@EnableScheduling

@Component

public class FooTask {

@Scheduled(cron="0 0/1 8-23 * * ?")

public void run(){

System.out.println("start run...........................................................");

}

}

b)spring.xml

<?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"

<!-- auto scan task -->

<task:annotation-driven/>

<context:annotation-config/>

<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>

<context:component-scan base-package="com.task"/>
