SpringBoot 버전 변경 후 매핑 문제

안녕하세요 강의를 보여 따라하던중 

@NotEmpty 어노테이션이 안되는걸보고 질문을 검색하니 SpringBoot 버전을 변경해야 한다고 하셔서

build.gradle 파일을 교재에 나와있는데로 복붙하였습니다. 

근데 그 이후부터 localhost:8080을 들어갈때 마다 아래와 같은 에러가 나면서 들어가지지를 않습니다. 코드에 문제가 있는건지 궁금합니다.

그리고 main밑에 생긴 generated 폴더도 무엇인지 궁금합니다.

혹시 버전때문에 이 글 보시는 분은 아래와 같이 하시면 정상작동합니다!!

build.grdle 의존성에

implementation 'org.springframework.boot:spring-boot-starter-validation'

추가 하시면 

@NotEmpty(message) 쓰실 수 있습니다!!!

안녕하세요. 첫단추님

1. generated는 다음을 참고해주세요. https://www.inflearn.com/questions/153026

2. 다음 링크의 강의 소스 코드를 실행해서 정상 동작하는지 먼저 확인해주세요.

https://www.inflearn.com/course/%EC%8A%A4%ED%94%84%EB%A7%81%EB%B6%80%ED%8A%B8-JPA-%ED%99%9C%EC%9A%A9-1/lecture/86625?tab=curriculum

그리고 해당 소스 코드로 문제가 되는 부분을 찾아서 해결해보시겠어요? 특히 .html 파일들을 복사해서 붙이는 방식으로 어디 부분이 문제가 있는지 확인해주세요.

 

만약 그래도 잘 해결되지 않으면

전체 프로젝트를 압축해서 구글 드라이브로 공유해서 링크를 남겨주세요.

구글 드라이브 업로드 방법은 다음을 참고해주세요.

https://bit.ly/3fX6ygx

 

주의: 업로드시 링크에 있는 권한 문제 꼭 확인해주세요

 

추가로 다음 내용도 코멘트 부탁드립니다.

1. 실행 방법을 알려주세요.

2. 어떻게 문제를 확인할 수 있는지 자세한 설명을 남겨주세요.

감사합니다.
