电子商务网站使用MVC模式B/S结构功能不是很全适合初学者看

	if(commodityID!=null){
			DBConnectBean dbBean=new DBConnectBean("sun.jdbc.odbc.JdbcOdbcDriver","jdbc:odbc:shopping","","");
			for (int i=0;i<commodityID.length;i++){
				Hashtable tmptable=new Hashtable();
				System.out.print(" zheggeeeg   "+commodityID[i]);
				tmptable=dbBean.getOneRecord("select card,num,price,picture from commodity where id="+commodityID[i]);
				commodity=new Hashtable();
//少加了这句 就很可怕了，每次的东西都一样哦 注意 去查查
				commodity.put("id".toUpperCase(),commodityID[i]);
				commodity.put("card".toUpperCase(),tmptable.get("card".toUpperCase()));
				commodity.put("num".toUpperCase(),tmptable.get("num".toUpperCase()));
				commodity.put("price".toUpperCase(),tmptable.get("price".toUpperCase()));
				commodity.put("picture".toUpperCase(),tmptable.get("picture".toUpperCase()));
				//out.print(commodityID[i]+"   " +commodityNum);
				commodityList.add(commodity);
			}
			session.setAttribute("commodityList".toUpperCase(),commodityList);
		}
