要使用Eclipse用Java语言写商城购物JSP界面,你需要掌握Java EE开发和JSP技术。以下是一个简单的商城购物JSP界面示例,你可以参考:
index.jsp
```jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Shopping Cart</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div class="header">
<h1>Shopping Cart</h1>
</div>
<div class="main">
<div class="product">
<h2>Product Name</h2>
<p>$0.00</p>
<form method="post" action="addToCart.jsp">
<input type="hidden" name="product" value="Product Name">
<input type="hidden" name="price" value="0.00">
<button type="submit">Add to Cart</button>
</form>
</div>
</div>
<div class="cart">
<h2>Cart</h2>
<p><%= session.getAttribute("cartSize") %> items</p>
<form method="post" action="checkout.jsp">
<button type="submit">Checkout</button>
</form>
</div>
</body>
</html>
```
addToCart.jsp
```jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String product = request.getParameter("product");
String price = request.getParameter("price");
List<String[]> cart = (List<String[]>) session.getAttribute("cart");
if (cart == null) {
cart = new ArrayList<>();
}
cart.add(new String[] { product, price });
session.setAttribute("cart", cart);
session.setAttribute("cartSize", cart.size());
response.sendRedirect("index.jsp");
%>
```
checkout.jsp
```jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
List<String[]> cart = (List<String[]>) session.getAttribute("cart");
session.invalidate();
%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Shopping Cart</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div class="header">
<h1>Shopping Cart</h1>
</div>
<div class="main">
<h2>Thank you for your purchase!</h2>
<table>
<thead>
<tr>
<th>Product</th>
<th>Price</th>
</tr>
</thead>
<tbody>
<% for (String[] item : cart) { %>
<tr>
<td><%= item[0] %></td>
<td><%= item[1] %></td>
</tr>
<% } %>
</tbody>
</table>
</div>
</body>
</html>
```
这个示例使用了JSP和Servlet技术,通过表单提交将商品添加到购物车中。购物车中保存了商品名称和价格,结账时将购物车内容显示在结账页面中。你可以根据自己的需求来修改和扩展这个示例。注意,在实际开发中,还需要考虑安全性和性能等问题。
