jsp实现购物程序

王朝java/jsp·作者佚名  2006-12-16
窄屏简体版  字體: |||超大  

下面是我用JSP和数据库做的购物车的源程序:

注意:

1、重新计费部分还没有做好,大家自己动手吧!

2、下一版本将用session做。

//shop_cart.jsp

<%@ page contentType="text/html;charset=gb2312"%>

<%@ page session="true" %>

<%@ page language="java" import="java.sql.*" %>

<jsp:useBean id="bka" scope="page" class="shop.bka" />

<%

String product_type;

String action;

int product_id;

int curpage;

//商品类型

if (request.getParameter("product_type")==null){

product_type="all";

}else{

product_type=request.getParameter("product_type");

}

//页数和商品类型参数,可以在“继续购物”时返回到上次购物的页面

if (request.getParameter("curpage")==null){

curpage=1;

}else{

curpage=java.lang.Integer.parseInt(request.getParameter("curpage"));

}

//动作

if (request.getParameter("action")==null){

action="view";

}else{

action=request.getParameter("action");

}

//商品编号

if (request.getParameter("product_id")==null){

product_id=0;

}else{

product_id=java.lang.Integer.parseInt(request.getParameter("product_id"));

}

int bbb;

bbb=1;

Integer num = new Integer(bbb);

//商店编号

session.putValue("shop_id",num);

//顾客username

session.putValue("guest_name","asp2001");

String guest_name=(String)session.getValue("guest_name");

Integer shop_id=(Integer)session.getValue("shop_id");

java.lang.String sql;

java.sql.ResultSet rs;

if (action.compareTo("add")==0) {

sql="select cart_quantity from shop_cart where cart_shop_id=" + shop_id

+ " and cart_guest_id='" + guest_name + "' and cart_product_id=" + product_id ;

rs = bka.executeQuery(sql);

if (rs.next()){

int cart_quantity;

cart_quantity=java.lang.Integer.parseInt(rs.getString("cart_quantity"))+1;

sql="update shop_cart set cart_quantity=" + cart_quantity + " where cart_shop_id="

+ shop_id + " and cart_guest_id='" + guest_name + "' and cart_product_id=" + product_id ;

rs = bka.executeQuery(sql);}

else

{

sql="insert into shop_cart (cart_shop_id,cart_guest_id,cart_product_id,cart_quantity) values ('" + shop_id + "','"

+ guest_name + "','" + product_id + "',1)";

rs = bka.executeQuery(sql);

}

}

if (action.compareTo("clear")==0) {

sql="delete from shop_cart where cart_shop_id=" + shop_id + " and cart_guest_id='" + guest_name + "'";

rs = bka.executeQuery(sql);

}

if (action.compareTo("delete")==0) {

sql="delete from shop_cart where cart_shop_id=" + shop_id + " and cart_guest_id='"

+ guest_name + "' and cart_product_id=" + product_id ;

rs = bka.executeQuery(sql);

}
