[질문 내용]

memberController 부분은 @NotEmpty가 잘 동작 하였고

itemController 에서 item을 생성할 때에도 member와 

동일하게 @Valid 체크를 해주려고 했습니다.

그런데 오류가 발생하는데 어느부분에서 문제인지 잘 모르겠습니다 ㅠ

Field error in object 'bookForm' on field 'name': rejected value []; codes [NotBlank.bookForm.name,NotBlank.name,NotBlank.java.lang.String,NotBlank]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [bookForm.name,name]; arguments []; default message [name]]; default message [공백이면 안됩니다.]

저도 비슷하게 동일한 문제 겪었는데 해결했고 방법은 다음과 같습니다.

기본적으로 강의를 따라가다보면 createItemForm.html 에 있는 form태그의 th:object="${form}" 으로  되어있으실거에요

여기를 th:object="${bookForm}" 으로 바꿔주세요

그리고 itemController의 Get매핑 /items/new에서 검증에 사용하기 위한 빈 객체를 모델로 넘기는데 이때 애트리뷰트의 이름을 "bookForm"으로 해주세요

그러면 잘 되실거에요

결국 현재 원리는 공부중이지만 (김영한 선생님께서 알려주실수도!!!) 처음에 등록화면에 접근할 떄 넘기는 객체의 이름이 DTO로 사용하는 클래스의 이름과 동일해야 하는것이 아닌가?? 하는 추측을 하고있어요

안녕하세요. 박시균님

앞에 한상우님께서 답을 남겨주신 부분이 맞습니다.

기존 코드

@PostMapping("/items/new")
public String create(@Valid BookForm form , BindingResult result){

수정 코드

@PostMapping("/items/new")
public String create(@Valid @ModelAttribute("form") BookForm form , BindingResult result){

관련해서 MVC1편 강의에서 자세히 알려드립니다^^

(@ModelAttribute 생략시 어떻게 되는지 복습해보시면 이해가 되실거에요.)

감사합니다.

안녕하세요. 시균님

전체 프로젝트를 압축해서 구글 드라이브로 공유해서 링크를 남겨주세요.

구글 드라이브 업로드 방법은 다음을 참고해주세요.

https://bit.ly/3fX6ygx

추가로 다음 내용도 코멘트 부탁드립니다.

1. 실행 방법을 알려주세요.

2. 어떻게 문제를 확인할 수 있는지 자세한 설명을 남겨주세요.

감사합니다.

1.db키고 localhost:8080 으로 접속

2.로그인 버튼을 누른후 아이디 : test  비번 :123 입력후 로그인

3.상품등록 버튼 클릭

4. 상품명을 제외하고 가격,수량,저자,isbn칸에는 값을 넣어주고  submit 버튼 클릭을 하면 

오류 확인가능합니다.

안녕하세요. 박시균님

name 값이 서버에 정상적으로 전달되지 않은 듯 합니다.

이 부분을 확인해주세요.

감사합니다.

name값이 서버에 정상적으로 전달되지 않았다는 말이 정확히 어떤 뜻인지 잘 모르겠네요 ㅠ

상품명을 정상적으로 입력하면 저장도 잘되고 잘 동작합니다.

그런데 회원가입 할때처럼 공백을 입력해주면 저런식으로  validation 해주는 기능을 작동하게 해주려고 질문한 코드를 작성했는데 상품을 등록할때는 공백을 입력해주면 질문글에 작성한 오류가 뜹니다.

회원가입과 상품등록 할때의 차이가 무엇일까요??ㅠ
