一个简单网上商城系统。实现有购物车等。
1.设计一个Item类,包括:一个商品对像,一个数量,一个小计
2.设计一个servlet类
先从session中取,看有没有Hashmap类,这是一个购物车
Hashmap类结构
键 值
商品id Item类
从session中取出HashMap:
1.先看session中有没有,有则取出,没有则创建
2.看HashMap中的键有没有这个商品的id号,如果表示第二次购买,则数量加1,没有则新建一个HashMap类
3.跳转页面-->显示购物车详细-A simple online store system. Realization of shopping carts.
Design an Item class, including: a commodity like a number, a small meter
(2) design a servlet class
Start the session to take to see if there Hashmap class, which is a shopping cart
The structure of the HashMap class
Key value
Goods the id the Item class
Remove the HashMap from the session:
A. Look at the session there, remove, did not create
2. HashMap key id of the commodity, if the second purchase, the number 1, does not create a new HashMap class
Jump page-> show cart in detail
