Spring Timer实现

定时器：继承java.util.TimerTask类实现run方法

package com.zbb.framework.util.timer;

import java.util.TimerTask;

import com.zbb.business.user.service.IUsOrderService;
/**
 * 
 * @author Vortex
 * 继承java.util.TimerTask类实现run方法
 * 该类实现spring定时器功能，spring配置文件spring-util.xml
 * 该定时器功能实现限制用户在规定时间内支付订单，否则取消支付权限
 */
public class TimerTaskExample extends TimerTask{
	private static boolean isrunning = true;
	
	private IUsOrderService usOrderService;
	@Override
	public void run() {
		  if(!isrunning){
			  isrunning = true;
			  /*
			   * 业务实现区
			   */
			try {
				  usOrderService.updateByIds();
			} catch (Exception e) {
				e.printStackTrace();
			}
			  isrunning = false;
		  }else{
			  System.out.println("定时器启动。。。");
			  isrunning = false;
		  }
	}
	public IUsOrderService getUsOrderService() {
		return usOrderService;
	}
	public void setUsOrderService(IUsOrderService usOrderService) {
		this.usOrderService = usOrderService;
	}
