一、结算购物车

建立实体类order

package com.zking.entity;

//订单实体类

	private long id;
	private long uid;
	private Date orderTime;
	private String consignee;
	private String phone;
	private String postalcode;
	private String address;
	private int sendType;
	private Date sendTime;
	private float orderPrice;
	private int orderState;
	
	public long getId() {
		return id;
	}
	public void setId(long id) {
		this.id = id;

}

orderitem

package com.zking.entity;
 
public class OrderItem {
	
	private long id;
	private long oid;
	private String bid;
	private int quantity;
	
	public long getId() {

	}
	
}

orderDao

package com.zking.dao;
 
import java.util.List;
 
import com.zking.entity.Order;
import com.zking.util.baseDao;
import com.zking.util.PageBean;
 
//订单
public class OrderDao extends baseDao{
	
	
	public void add(Order order) throws Exception {

		String sql = " select * from t_easyui_order order by orderTime desc ";
		return super.executeQuery(sql, Order.class, pageBean);
	}
 
}

oerderitemDao

package com.zking.dao;
 
import com.zking.entity.OrderItem;
import com.zking.util.baseDao;
 
//订单项
public class OrderItemDao extends baseDao{

}

购物车结算思路：
1、数据入订单表
2、数据入订单项表
3、下单结束后，要将商品的销售数量发生改变

shoppingVoAction

//  购物车结算
	public void createOrder(HttpServletRequest req, HttpServletResponse resp) {	
		//获取用户id（uid）
		User cuser = (User) req.getSession().getAttribute("cuser");
		//判断是否登录
		if(cuser==null) { return; }
		//组装数据
		Order order=new Order();
		order.setAddress(shoppingVo.getAddress());
		order.setConsignee(shoppingVo.getConsignee());
		//订单价格总计
		float orderPrice=0;
		String pageStr = shoppingVo.getPageStr();//获取购物车信息
		if(StringUtils.isNotBlank(pageStr)&&pageStr.length()>1) {
			for (String item:pageStr.substring(1).split(",")) {//进行截取分割
				String[] itemEle = item.split("-");
					orderPrice += Float.valueOf(itemEle[3]);
			}
		}
		order.setOrderPrice(orderPrice);
		order.setOrderState(1);
		order.setPhone(shoppingVo.getPhone());
		order.setPostalcode(shoppingVo.getPostalcode());
		order.setSendType(shoppingVo.getSendType());
		order.setUid(cuser.getId());
		try {
			orderDao.add(order);
			//取最新的一条订单
			Order newest = orderDao.list(null, null).get(0);
			if(StringUtils.isNotBlank(pageStr)&&pageStr.length()>1) {
				for (String item:pageStr.substring(1).split(",")) {
					OrderItem orderItem=new OrderItem();
					String[] itemEle = item.split("-");
					orderItem.setBid(itemEle[0]);
					orderItem.setOid(newest.getId());
					orderItem.setQuantity(Integer.valueOf(itemEle[2]));
					orderItemdDao.add(orderItem);
					
					//修改销量
					Book book=new Book();
					book.setName(itemEle[0]);
					book.setSales(Integer.valueOf(itemEle[2]));
					bookDao.editSales(book);
				}
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
