Spring+quartz删除超时订单的测试

建立一张简单的表：myorder（order是保留字不能做数据库表名），字段：id,和date（下订单的时间）

status(是否支付的状态)，uid（外键，关联下订单的人）。

applicationContext.xml文件：

    import domain.Order;
    
    import interfa.OrderInter;
    
    public class OrderImp implements OrderInter {
    private SessionFactory sessionFactory;
    public void setSessionFactory(SessionFactory sessionFactory) {
    	this.sessionFactory = sessionFactory;
    }
    	public void addOrder() {
    		// TODO Auto-generated method stub
    		Session s=sessionFactory.openSession();
    		Transaction t=s.beginTransaction();
    		Order order=new Order(new Date());
    		s.save(order);
    		System.out.println("加一条订单");
    		t.commit();
    		s.close();
    	}
    	public void delete() {
    		// TODO Auto-generated method stub
    		Session s=sessionFactory.openSession();
    		Transaction t=s.beginTransaction();
    		List<Order> list=s.createQuery("from Order order by id desc").list();
    		for(int i=0;i<list.size();i++){
    			Date date=new Date();
    			if((date.getTime()-list.get(i).getDate().getTime())/1000>3*60){
    				 Query query=s.createQuery("delete from Order where id="+list.get(i).getId()+"");
    				 query.executeUpdate();
    				 System.out.println("删除一条存在3分钟的订单");
    				t.commit();
    			} 
    			else{
    				System.out.println("没有可删除的订单");
    			}
    		
    			}
    		}
    	}

test

package test;
    
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    import interfa.OrderInter;
    
    public class Test {
    public static void main(String[] args) {
    	ApplicationContext applicationContext= new ClassPathXmlApplicationContext("applicationContext.xml");
    	System.out.println("begin ");
    }
    }

这样就每隔一分钟添加一条数据库，删除一条未支付时间超过三分钟的订单：
