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

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");//Service
		
		timer.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>
