1.配置web.xml檔案：

<listener>
<listener-class>
監聽器的路徑
</listener-class>
</listener>

2.編寫java 類

package com.ronhe.romp.core.listener;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.http.HttpServlet;

import com.ronhe.romp.core.utils.HtcSyncUtils;

public class NewsListener extends HttpServlet implements ServletContextListener{

	/**
	 * 
	 */
	private static final long serialVersionUID = -8135741626468992930L;

	//伺服器停止時執行該事件
	@Override
	public void contextDestroyed(ServletContextEvent arg0) {
		
	}

	//伺服器啟動時執行該事件
	@Override
	public void contextInitialized(ServletContextEvent arg0) {
		Thread thread = new Thread(new Runnable(){  
            public void run(){  
            	while (true) {
            		try {
            			Thread.sleep(6 * 1000);//休眠1分鐘
            			HtcSyncUtils.syncNewsTables();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
				}
            }});  
		thread.start();
	}

}
 

啟動即可
