jsp中监听器和定时器的结合的程序

package Unit.Test;

import javax.servlet.ServletContext;
import javax.servlet.ServletContextAttributeEvent;
import javax.servlet.ServletContextAttributeListener;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

import test.TimerTest;

public class ServletConextListener implements ServletContextListener,
		ServletContextAttributeListener {

	private ServletContext servletContext;

	private String AttributeName;

	private Object AttributeValue;

	public void contextDestroyed(ServletContextEvent sce) {
		System.out.println("####ServletContext上下文销毁");

	}

	public void contextInitialized(ServletContextEvent sce) {
		servletContext = sce.getServletContext();
		
		TimerTest test=new TimerTest();
		//这个是定时器的内容
		
		System.out.println("####上下文初始化");
		
		System.out.println("####ServletContext当前初始目录为:"
				+ this.servletContext.getRealPath("/"));
		
	}

	public void attributeAdded(ServletContextAttributeEvent sce) {
		AttributeName = sce.getName();
		AttributeValue = sce.getValue();
		System.out.println("####ServletContext增加一个属性:");
		System.out.println("AttributeName:" + AttributeName);
		System.out.println("AttributeValue:" + AttributeValue);

	}

	public void attributeRemoved(ServletContextAttributeEvent sce) {
		AttributeName = sce.getName();
		AttributeValue = sce.getValue();
		System.out.println("####ServletContext删除一个属性:");
		System.out.println("AttributeName:" + AttributeName);
		System.out.println("AttributeValue:" + AttributeValue);
	}

	public void attributeReplaced(ServletContextAttributeEvent sce) {
		AttributeName = sce.getName();
		AttributeValue = sce.getValue();
		System.out.println("####ServletContext替换一个属性:");
		System.out.println("AttributeName:" + AttributeName);
		System.out.println("AttributeValue:" + AttributeValue);
	}

}

 

上面是监听器的内容，下面是定时器的内容

package test;

import java.io.IOException;
import java.util.Date;
import java.util.Timer;

public class TimerTest {
	public TimerTest(){
		Date time=new Date();
		time.setHours(17);
		time.setMinutes(48);
		time.setSeconds(20);
		Timer timer = new Timer();
		timer.schedule(new MyTask(),time);//在1秒后执行此任务,每次间隔2秒
}

static class MyTask extends java.util.TimerTask{
   @Override
   public void run() {
 
    System.out.println("我是来测试的。。我两秒出来一次");
   }
}
}

 下面是xml的配置方法

<listener>
    <listener-class>Unit.Test.ServletConextListener</listener-class>
</listener>
