show details of all orders placed by customer - mysql

Question

I am developing an E-Commerce website(Spring MVC, java, mySql, Hibernate) for my college project. I have various models like customer,product,orders,custOrderHistory, etc.
I am able to show all customer details(in admin page) and all products for a customer to browse through.
But the problem I am facing is, how do I show the Orders and order history of a customer?
My orders table has orderId, productId, quantity and total price. but to show the product name, I have to use the productId and rerieve the Product name from product table.
I have no clue on how to do it.
Till now, i was using the jstl foreach loop to iterate the products in the productList.jsp page and displaying them in a table.
But as i told above, i need to retrieve data from 3-4 tables at once, like productName(from product table), productManuacturer(also from product table), ShippingAddress (from customer table). And I am unsure how to do this.
Edit 1: I asked this question from someone else's computer and didn't have my code with me then.
So, I am giving my code here.

edit 2: how do I store the data in the ustomerorder table and orderhistory table, and also, how do i show it on a jsp page?

Answer 1

you should have a CustomerId column in order table for detecting the order is associated with which customer. Simply insert logged in userid in that and fetch the customer name by making join with customer table.

Answer 2

You should have customerid in your order table. So that you can fetch the customer's order history by providing customerid.
