JavaEE作业-实验三
目录
1 实验内容
简单的线上图书交易系统的web层
2 实验要求
①采用SpringMVC框架，采用REST风格
②要求具有如下功能：商品分类、订单、购物车、库存
③独立完成，编写实验报告
3 思路
①确保项目结构清晰，按照MVC的结构进行组织
②在pom.xml中添加SpringMVC相关依赖，以及其他可能需要的依赖，比如数据库连接池、模板引擎等：
③配置web.xml文件，配置DispatcherServlet和Spring监听器：
④在WEB-INF目录下创建相关文件，配置相关内容：
⑤在com.exp.controller包下创建控制器类，使用@RestController注解，以REST风格暴露接口
⑥创建JSP文件，用于显示前端页面。
4 核心代码
①BookController类
@RestController
@RequestMapping("/books")
public class BookController {
@Autowired
private BookService bookService;
@GetMapping
public List<Book> getAllBooks() {
return bookService.getAllBooks();
}
@GetMapping("/{id}")
public Book getBookById(@PathVariable Long id) {
return bookService.getBookById(id);
}
@PostMapping
public void addBook(@RequestBody Book book) {
bookService.addBook(book);
}
@PutMapping("/{id}")
public void updateBook(@PathVariable Long id, @RequestBody Book book) {
book.setId(id);
bookService.updateBook(book);
}
@DeleteMapping("/{id}")
public void deleteBook(@PathVariable Long id) {
bookService.deleteBook(id);
}
}
②OrderController类
@RestController
@RequestMapping("/orders")
public class OrderController {
@Autowired
private OrderService orderService;
@GetMapping
public List<Order> getAllOrders() {
return orderService.getAllOrders();
}
@GetMapping("/{id}")
public Order getOrderById(@PathVariable Long id) {
return orderService.getOrderById(id);
}
@PostMapping
public void addOrder(@RequestBody Order order) {
orderService.addOrder(order);
}
@PutMapping("/{id}")
public void updateOrder(@PathVariable Long id, @RequestBody Order order) {
order.setId(id);
orderService.updateOrder(order);
}
@DeleteMapping("/{id}")
public void deleteOrder(@PathVariable Long id) {
orderService.deleteOrder(id);
}
}
③CartController类
@RestController
@RequestMapping("/cart")
public class CartController {
@Autowired
private CartService cartService;
@GetMapping("/{userId}")
public List<CartItem> getCartItemsByUserId(@PathVariable Long userId) {
return cartService.getCartItemsByUserId(userId);
}
@PostMapping
public void addCartItem(@RequestBody CartItem cartItem) {
cartService.addCartItem(cartItem);
}
@PutMapping("/{id}")
public void updateCartItem(@PathVariable Long id, @RequestBody CartItem cartItem) {
cartItem.setId(id);
cartService.updateCartItem(cartItem);
}
@DeleteMapping("/{id}")
public void deleteCartItem(@PathVariable Long id) {
cartService.deleteCartItem(id);
}
}
④InventoryController类
@RestController
@RequestMapping("/inventory")
public class InventoryController {
@Autowired
private InventoryService inventoryService;
@GetMapping("/{bookId}")
public Inventory getInventoryByBookId(@PathVariable Long bookId) {
return inventoryService.getInventoryByBookId(bookId);
}
@PostMapping
public void addInventory(@RequestBody Inventory inventory) {
inventoryService.addInventory(inventory);
}
@PutMapping("/{id}")
public void updateInventory(@PathVariable Long id, @RequestBody Inventory inventory) {
inventory.setId(id);
inventoryService.updateInventory(inventory);
}
@DeleteMapping("/{id}")
public void deleteInventory(@PathVariable Long id) {
inventoryService.deleteInventory(id);
}
}
