BookForm 을 setter 대신 생성자로 했는데, int price 와 int stockQuantity 에서 missmatch Error 가 떴어요. CreateForm 도 그렇고 UpdateFrom 도 그렇고 빈 폼을 넘겨줄때 java 기본값이 0 인데 참조변수 기본값 null 이 들어가서 에러가 뜨는것 같은데 맞나요.? 그래서 아래와 같이 @nullable을 넣으니까 해결되긴 했는데, 이렇게 사용해도 다른 사이드에 악영향을 끼칠 가능성은 없을까요..? 답변 항상 감사합니다. public BookForm (Long id , String name , @Nullable int price , @Nullable int stockQuantity , String author , String isbn) { this . id = id ; this . name = name ; this . price = price ; this . stockQuantity = stockQuantity ; this . author = author ; this . isbn = isbn ; }
안녕하세요. 강의 중 단위테스트가 중요하다고 하셔서 진행하고싶은데 방향성이 궁금해서 질문드립니다. 1) Repository를 jpa 사용하지 않고 Map을 이용하던가 해서 순수 java로 만든 후 service에 의존시켜서 진행하는 것인가요?? 2) 그리고 실무에서 test code를 짤 때 controller, service, repository에 대해서 모두 다 짜는지... 아니면 화면단 보다는 비즈니스 로직이 있는 부분 위주로 짜는지도 궁금합니다.
안녕하세요 강사님 언제나 좋은 강의 감사드립니다. 강의 내용을 따라서 열심히 따라 하고는 있는데, TestPropertySources로 우선순위를 먼저 받게끔 작업을 했는데 테스트 코드가 통과를 해서 혹시 뭐가 잘못 됐는지 여쭤보고 싶어서 질문을 남깁니다. 위의 코드를 보면 기존 application.yml의 server.port가 7443이고, test.yml의 설정이 6663인데, 해당 코드를 돌려보니 application.yml의 설정값을 우선순위로 읽어들여서 테스트 코드가 성공하였습니다. 혹시 현재 기준으로 우선순위가 변경이 된건지, 아니면 제가 무슨 실수를 한 것인지 한번만 봐 주시면 감사드리겠습니다
jpashop으로 하면 파일도 만들어지고 연결성공하는데요 여기까지오면 연결이 되지않고 아래와 같은 오류가 뜹니다 뭐가 문제일까요 영상에서 했던 것과 다르게 실시햇던 것은 다운은 받았으나, 터미널로 진행하는 부분을 정확하게 인지하지 못해서 주소창에 localhost:9092(제포트)/h2-console 로 접근해서 jdbc:h2:~/jpashop 연결했습니다. 추가 ++) 위와 같이 실행해서 h2 페이지를 연 후에도 같은 오류가 나더라고요. 전에 다른 강의에서 썼던 db입니다. 해당 데이터 베이스로는 잘 접속이 되는데 이걸로 application에 url설정 넣고 사용해도 되는건가요?
[질문 템플릿] 1. 강의 내용과 관련된 질문인가요? (예/아니오) 2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예/아니오) 3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오) [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

안녕하세요 ! 4:07 쯤에 선생님은 오류나시는데 저는 오류가 안 나서 어디가 문제인지 잘 모르겠어서 질문드립니다 ㅜㅜ 죄송하지만 하나 더 여쭤볼게 있습니다! ctrl + shift + enter 이 코드 자동완성(; 붙이기)인 것으로 알고 있는데 어느 순간 단축키가 안 먹힙니다ㅜ 다른 단축키는 잘 되는데 제가 뭘 잘못 만진건가요?
DB는 Mysql로 사용하고있습니다. SpringConfig에서 JdbcTemplateRepository를 연결하고 테스트를하면 오류가 납니다. org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: Unknown column 'encrypted_password' in 'field list' 오류 나는 지점을 확인해보면 JdbcTemplateRepository의 Number key = jdbcInsert.executeAndReturnKey(new MapSqlParameterSource(parameters)); 이 행을 가르킵니다.
안녕하세요 영한님! 강의가 참 유익합니다 감사합니다. 강의를 다 마치고 개인 프로젝트를 만들어 보고 있는데, 궁금한 것이 생겨서 질문 올립니다. Album이라는 도메인이 여러개의 Theme를 가질 수 있습니다. 이 Theme는 enum으로 {sad, happy, interresting..} 이런 식으로 미리 정해두고, 사용자는 자신의 Album에 맞는 Theme를 최대 5개를 선택하여 저장할 수 있습니다. 생각나는 방법은 다음의 2가지입니다. Album에 String필드로 구분자를 이용해 저장하는 방법. ex) sad%happy%interresting Album에 값타입 컬렉션으로 Set<Theme>을 넣는 방법. Theme는 enum. 저는 테마로 검색도 가능하도록 하고싶습니다. 검색 조건에 여러 Theme를 지정하여 해당 Theme를 모두 가진 Album만 조회하고 싶습니다. 두 방법 모두 제 생각엔 가능할 것으로 보이는데, 제가 궁금한 것은 무엇이 합리적인방법인지, 만약 흑백으로 가려지지 않는다면 장단점이 무엇인지 알 고 싶습니다.
강의해서 1:N 은 페이징처리를 하려고하면 인메모리로 다 올려버린다고 이해하였습니다. 하지만 약간 이해가 안된다고 해야될까요? 결론적으로 정확하게 메커니즘을 제가 이해를 못하는거 같습니다. 강의를 3~4번 다시 보구 있습니다만 몇가지 질문드립니다. 1. jpql에서 1:N으로 fetch join을 하여 뻥튀기? 데이터가 되어 distinct로 해결하였습니다. 여기서 추가로 페이징을 넣으면 인메모리로 바꿘다고하셨는데, 정확하게 jpa에서 예를 들면 select distinct o from order o join fetch o,orderItems oi 이렇게 하구 페이징처리를 하면 인메모리로 된다고하셨는데 distinct를 하기전에 jpql이 1:N인걸 인지하고 인메모리로 일다누올린다는건지 궁금합니다 2. 위에 내용과 동일하게 단순히 1:N 어노테이션만 보구 컬렉션 연관관계가 되는기준으로 페이징을 처리하면 워닝 에러가 나는지 궁금합니다
안녕하세요 제가 다른 강의 때문에 자바 1.8버전을 사용하고 있고 인텔리제이도 잘 알지도 못해서 아무거나 깔다가 인텔리제이 에듀를 깔아서 사용하고 있었슴미다 cmd에서 오류가 생기는 것 같아 인텔리제이 에듀를 삭제하고 커뮤니티를 다시 깔아서 처음부터 하려고 하였는데 "Error running 'All in hello-spring': No junit.jar" 라는 메시지와 함께 실행이 되지 않습니다ㅜㅜ 왜 이러는 것일까요 자바 1.8이나 자바 11버전을 용도에 따라 골라 사용하거나 그럴 수는 없는건가요? ---------------------------------------------------------------------------------------------------------------- https://stackoverflow.com/questions/4757800/configuring-intellij-idea-for-unit-testing-with-junit 페이지를 참고하여 junit을 수동으로 추가한거같은데 "Tests were not found in module 'hello-spring.main'. Use module hello-spring.test instead" 라는 메시지가 뜹니다
