显示客户下的所有订单的详细信息

Posted 2023-02-24

【中文标题】显示客户下的所有订单的详细信息

【英文标题】：show details of all orders placed by customer

【问题描述】：

我正在为我的大学项目开发​​一个电子商务网站（Spring MVC、java、mysql、Hibernate）。我有各种模型，如客户、产品、订单、custOrderHistory 等。

我能够显示所有客户详细信息（在管理页面中）和所有产品供客户浏览。

但我面临的问题是，如何显示客户的订单和订单历史记录？

我的订单表有 orderId、productId、数量和总价。但要显示产品名称，我必须使用 productId 并从产品表中检索产品名称。

我不知道该怎么做。

到目前为止，我一直在使用 jstl foreach 循环来迭代 productList.jsp 页面中的产品并将它们显示在表格中。 但正如我上面所说，我需要一次从 3-4 个表中检索数据，例如 productName（来自 product 表）、productManuacturer（也来自 product 表）、 ShippingAddress（来自 customer 表）。我不确定该怎么做。

编辑 1：我从别人的电脑上问了这个问题，当时我的代码没有随身携带。 所以，我在这里给出我的代码。

编辑2：如何将数据存储在ustomerorder表和orderhistory表中，以及如何在jsp页面上显示？

【参考方案1】：

您应该在订单表中有一个 CustomerId 列，用于检测订单与哪个客户相关联。只需在其中插入登录的用户 ID，然后通过与客户表连接来获取客户名称。

【参考方案2】：

您的订单表中应该有 customerid。这样您就可以通过提供 customerid 来获取客户的订单历史记录。
