J2EE,struts2 拦截器中获取 server

xml配置，监听器一定要在ContextLoaderListener后面

<listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 定时器 --><listener><listener-class>com.alpha.util.TimerListener</listener-class></listener>

 

推荐方法：

import java.util.Timer;import java.util.TimerTask;import javax.servlet.ServletContextEvent;import javax.servlet.ServletContextListener;import org.springframework.context.ApplicationContext;import org.springframework.web.context.support.WebApplicationContextUtils;/** * 安排指定的任务task在指定的时间firstTime开始进行重复的固定速率period执行 * @author JavaAlpha * @date 2013-10-30 13:46:15 */public class TimerListener implements ServletContextListener{private Timer timer = null;public void contextInitialized(ServletContextEvent servletContextEvent) {//在这里初始化监听器，在tomcat启动的时候监听器启动，可以在这里实现定时器功能timer = new Timer(true);//添加日志，可在tomcat日志中查看到servletContextEvent.getServletContext().log("定时发布Timer已启动！");ApplicationContext ac1 = WebApplicationContextUtils.getRequiredWebApplicationContext(servletContextEvent.getServletContext());//ApplicationContext ac2 = WebApplicationContextUtils.getWebApplicationContext(servletContextEvent.getServletContext());final EquipmentMaintainService emSvc = (EquipmentMaintainService) ac1.getBean("emService");//Servicetimer.scheduleAtFixedRate(new TimerTask() {            public void run() {                //设备维护管理--定时提醒EquipmentMaintainAction em = new EquipmentMaintainAction();System.out.println("-------定期检修提醒任务--------");em.timerTaskTbFTServiceRemind(emSvc);System.out.println("-------定期注油提醒任务--------");em.timerTaskTbFTOilingRemind(emSvc);System.out.println("-------维修工单提醒任务--------");em.timerTaskTbFTMaintainlistRemind(emSvc);System.out.println("-------报警提醒任务--------");em.timerTaskTbAlarmRemind(emSvc);            }}, 30000, 2000);// 这里设定将延时每十分钟固定执行//}, 1000 * 60 * 60 * 1, 1000 * 60 * 60 * 1);// 这里设定将延时每小时固定执行    //}, time, 1000 * 60 * 60 * 24);// 这里设定将延时每天固定执行//添加日志，可在tomcat日志中查看到servletContextEvent.getServletContext().log("已经添加定时发布任务！");}public void contextDestroyed(ServletContextEvent event) {// 在这里关闭监听器，所以在这里销毁定时器。timer.cancel();event.getServletContext().log("定时发布定时器销毁！");}}// web.xml配置内容//<!-- 定时器 -->//<listener>//<listener-class>com.alpha.util.TimerListener</listener-class>//</listener>
