안녕하세요.
이번엔 spring controller 에서 에러를 발견했습니다.

바로 이부분 인데요. 파라미터에 이름이 없다고 하는걸 보니 @PathVariable 이부분에 이름이 명시적을 안들어가서 그런걸로 보입니다.
제가 알기론 url의 itemId 와 @PathVariable 의 itemId 가 이름이 같으면 안적어줘도 된다고 알고 있는데 스프링 버전이 3으로 올라가면서 바뀐걸까요??
이렇게 수정하니 화면이 잘 나왔습니다.
@GetMapping("/{itemId}")
public String item(@PathVariable("itemId") Long itemId, Model model) {
System.out.println("BasicItemController.item");
Item item = itemRepository.findById(itemId);
model.addAttribute("item", item);
return "basic/item";
}
저처럼 안되는 분들이 많은것같아요.
