spring-listener&spring-task注解版本
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"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"

http://www.springframework.org/schema/task/spring-task-3.1.xsd">
<!-- auto scan task -->
<task:annotation-driven/>
<context:annotation-config/>
<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
<context:component-scan base-package="com.task"/>
