由于B2C商城系统的编码比较复杂,无法在短时间内给出完整的源代码。以下是一个简单的B2C商城系统的编码示例,供参考:
1. 后端代码(Java语言,基于Spring和MyBatis框架):
```
// 定义商品实体类
public class Product {
private int id;
private String name;
private String description;
private double price;
// 省略getter和setter方法
}
// 定义商品DAO接口
public interface ProductDao {
List<Product> getAllProducts();
Product getProductById(int id);
void addProduct(Product product);
void updateProduct(Product product);
void deleteProduct(int id);
}
// 定义商品服务接口
public interface ProductService {
List<Product> getAllProducts();
Product getProductById(int id);
void addProduct(Product product);
void updateProduct(Product product);
void deleteProduct(int id);
}
// 实现商品服务接口
@Service
public class ProductServiceImpl implements ProductService {
@Autowired
private ProductDao productDao;
@Override
public List<Product> getAllProducts() {
return productDao.getAllProducts();
}
// 省略其他方法的实现
}
// 定义订单实体类
public class Order {
private int id;
private int userId;
private List<Product> products;
private double totalPrice;
// 省略getter和setter方法
}
// 定义订单DAO接口
public interface OrderDao {
void addOrder(Order order);
}
// 定义订单服务接口
public interface OrderService {
void addOrder(Order order);
}
// 实现订单服务接口
@Service
public class OrderServiceImpl implements OrderService {
@Autowired
private OrderDao orderDao;
@Autowired
private ProductService productService;
@Override
public void addOrder(Order order) {
// 计算订单总价
double totalPrice = 0;
List<Product> products = order.getProducts();
for (Product product : products) {
totalPrice += product.getPrice();
}
order.setTotalPrice(totalPrice);
// 扣减库存
for (Product product : products) {
Product p = productService.getProductById(product.getId());
p.setStock(p.getStock() - product.getQuantity());
productService.updateProduct(p);
}
// 保存订单信息
orderDao.addOrder(order);
}
}
// 定义RESTful API控制器
@RestController
@RequestMapping("/api")
public class ApiController {
@Autowired
private ProductService productService;
@Autowired
private OrderService orderService;
// 获取所有商品信息
@GetMapping("/products")
public List<Product> getAllProducts() {
return productService.getAllProducts();
}
// 根据商品ID获取商品信息
@GetMapping("/products/{id}")
public Product getProductById(@PathVariable int id) {
return productService.getProductById(id);
}
// 添加商品信息
@PostMapping("/products")
public void addProduct(@RequestBody Product product) {
productService.addProduct(product);
}
// 更新商品信息
@PutMapping("/products")
public void updateProduct(@RequestBody Product product) {
productService.updateProduct(product);
}
// 删除商品信息
@DeleteMapping("/products/{id}")
public void deleteProduct(@PathVariable int id) {
productService.deleteProduct(id);
}
// 下单
@PostMapping("/orders")
public void placeOrder(@RequestBody Order order) {
orderService.addOrder(order);
}
}
```
2. 前端代码(HTML、CSS、JavaScript):

<!-- 引入Vue.js -->

addToCart: function(product) {

if (item) {

} else {

},
// 从购物车中删除商品
