web 一个简单的监听

<!-- 测试监听，listener-class值为监听的路径 -->
<listener>
<listener-class>com.test.listener.Jurisdictionlistener</listener-class>
</listener>

启动就有用啦

package com.test.listener;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

public class Jurisdictionlistener implements ServletContextListener {

@Override
public void contextDestroyed(ServletContextEvent arg0) {

}

/**
* 测试
*/
@Override
public void contextInitialized(ServletContextEvent arg0) {
System.out.println("1111111111111111111111111");
}
}
