✏️ 상품 주문
상품 주문 컨트롤러
@Controller
@RequiredArgsConstructor
public class OrderController {
private final OrderService orderService;
private final MemberService memberService;
private final ItemService itemService;
@GetMapping("/order")
public String createForm(Model model) {
List<Member> members = memberService.findMembers();
List<Item> items = itemService.findItems();
model.addAttribute("members", members);
model.addAttribute("items", items);
return "order/orderForm";
}
@PostMapping("/order")
public String order(@RequestParam("memberId") Long memberId,
@RequestParam("itemId") Long itemId,
@RequestParam("count") int count) {
orderService.order(memberId, itemId, count);
return "redirect:/orders";
}
}주문 폼 이동
- 메인 화면에서 상품 주문을 선택하면
/order를 GET 방식으로 호출 - OrderController의 createForm() 메서드
- 주문 화면에는 주문할 고객정보와 상품 정보가 필요하므로 model 객체에 담아서 뷰에 넘겨줌
주문 실행
- 주문할 회원과 상품 그리고 수량을 선택해서 submit 버튼을 누르면
/orderURL을 POST 방식으로 호출 - 컨트롤러의 order() 메서드를 실행
- 이 메서드는 고객 식별자(memberId), 주문할 상품 식별자(itemId), 수량(count) 정보를 받아서 주문 서비스에 주문을 요청
- 주문이 끝나면 상품 주문 내역이 있는
/ordersURL로 리다이렉트
