6:30에 test5.number는 왜 안되나요?그리고 println(TestObjectClass().number)도 똑같이 안되던데 println(TestObjectClass.number)하고 println(TestObjectClass().number)가 무슨 차이가 있나요?

안녕하세요~리액트(ts) 공부하고 있는 직장인입니다Link에 target="_blank"를 적용하면로컬에서는 제대로 보여지는데..build만 하면 Not Found 에러가 자꾸 보여집니다ㅠㅠ구글링으로 이것저것 해봤는데도 계속 동일한 현상이 나타나네요... a태그, button onClick까지 적용했지만build에선 에러가 계속 나요ㅠㅠ

안녕하세요. 강의 잘들으면서 많은 도움 받고 있습니다. 부모 프로세스가 fork()를 통해 자식 프로세스를 생성하고, exec()를 호출하여 새로운 프로그램으로 덮어씌어진 후, 부모 프로세스와 자식 프로세스가 병행 실행된다고 하신 것으로 알고 있습니다.이때 병행 실행의 의미가 부모 프로세스와 자식 프로세스 둘 다 실행상태라는 의미인지, 아니면 그냥 자식프로세스가 프로세스 목록에 추가된다는 의미인지 궁금합니다.

안녕하세요. 강사님께서 OrderProduct 클래스를 아래와 같이 작성하셨습니다.Order와 Product는 N:N 양방향 관계인데 이것을 피하기 위해 OrderProduct 클래스를 새로 생성하셨는데요.order 필드가 @ManyToOne이면 product 필드가 @OneToMany가 되어야 하는게 아닌가요?그래야 N:N 구조가 되는 것 같아서요!@Getter @NoArgsConstructor(access = AccessLevel.PROTECTED) @Entity public class OrderProduct extends BaseEntity { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; @ManyToOne(fetch = FetchType.LAZY) private Order order; @ManyToOne(fetch = FetchType.LAZY) private Product product; public OrderProduct(Order order, Product product) { this.order = order; this.product = product; } }

 강사님 제가 토스페이로 테스트를 진행중에결제성공 메시지가 나오는데 db에 데이터 변경점이 없어서 확인해보니까 토큰이 만료된 상태더라구요.토큰 만료됐을때 graphql에서는 unauthorization에러가 나왔는데 html liveServer에서는 따로 알 수 있는 방법 없을까요? 그리고 실제 서비스라면 accessToken이 만료되었을때 자동으로 refreshToken이 accessToken으로 변환되면서 고객이 느낄때는 결제 진행에 아무 무리없는 상태로 표시되나요? 테스트할때는 refreshToken도 직접 요청해서 받아오고 다시 header에 세팅하고 테스트하는거라서 이게 실제 서비스에서는 어떤 로직으로 자동화되는지 궁금합니다.

OptimisticLockStockService 에 decrease 메서드에 @트랜잭션을 사용하지 않는 경우 테스트 코드가 멈추지 않는 문제가 있었습니다.이런 경우 왜 그런건가요??

@InitBinder 에 여러 개의 검증이 등록되고 @Validated에 의해 실행될 때 각 검증을 구분하는 것이 Validator의 supports라고 설명하셨는데그래서 임의로 UserValidator를 추가하고 실행해본 결과 IllegalStateException이 발생하는 것을 확인했습니다. 유사한 질문으로 https://www.inflearn.com/questions/811214/initbinder-%EC%A7%88%EB%AC%B8%EC%9E%88%EC%8A%B5%EB%8B%88%EB%8B%A4또한 확인했습니다. @InitBinder에 모델명을 등록하는 방식, 한 컨트롤러에서 하나의 모델 객체만 사용하는 방식 등 을 사용하게 된다면 결국 Validator의 supports는 다른 타입을 받게되는 경우가 없는 것 같은데 어떤 경우에 사용되는 것 일까요?  

안녕하세요 호돌맨님 :) 좋은 강의 늘 감사드립니다.Controller Test 할 때 질문이 있습니다. 강의에서 호돌맨님께서는 @SpringBootTest 사용하셨는데 저는 한 번 @WebMvcTest를 사용해보고 있습니다.그러다보니 문제가 하나 발생을 하더라구요. 우선 PostController 쪽 코드를 보여드리겠습니다.@GetMapping("/posts") public ApiResponse<List<PostResponse>> getAll(@ModelAttribute PostSearch postSearch) { List<PostResponse> posts = postService.getAllPost(postSearch); return ApiResponse.ok(posts); }보시면 게시글을 전체 조회하는 이 메서드의 경우에는 인증이 따로 필요없이 바로 조회가 되게 했는데요. Insomnia 라는 프로그램을 통해서 테스트했을 때 따로 인증하지 않아도 전체 조회 요청이 성공하는 것을 확인했습니다.그런데 테스트코드를 작성할 때 인증 처리를 해주지 않으면 계속해서 401 에러가 발생을 하더라구요.@DisplayName("게시글을 전체 조회한다.") @CustomMockUser //todo 실제로는 인증이 필요없는데도 테스트 통과를 위해서 인증 처리를 해줘야 하는 것인가? @Test void getAllPosts() throws Exception { // given List<Post> posts = IntStream .range(1, 5) .mapToObj(i -> Post.of(FREE, i + "번 제목입니다.", i + "번 내용입니다.")) .toList(); List<PostResponse> response = changePostListToPostResponseList(posts); // when when(postService.getAllPost(any())).thenReturn(response); //then mockMvc.perform( MockMvcRequestBuilders.get("/api/posts") ) .andDo(MockMvcResultHandlers.print()) .andExpect(MockMvcResultMatchers.jsonPath("$.code").value(200)) .andExpect(MockMvcResultMatchers.jsonPath("$.message").value("OK")) .andExpect(MockMvcResultMatchers.jsonPath("$.status").value("OK")) .andExpect(MockMvcResultMatchers.jsonPath("$.data").isArray()) .andExpect(MockMvcResultMatchers.status().isOk()); }@CustomMockUser 어노테이션을 붙여줘야 테스트 통과가 되는 상황입니다. 실제 원하는 기능은 인증없이 전체 조회 되게 하는 것이 목표인데 테스트 통과를 위해서 @CustomMockUser 어노테이션을 붙여주는 것이 올바른 테스트인지 궁금합니다! 혹시 이게 @WebMvcTest와 관련없는 다른 문제라면 알려주시면 한 번 제가 더 찾아보겠습니다..!

질문은 아니지만 다른 분들도 쉽게 보시고 이해하실 수 있도록 해당 수업의 질문으로 남기도록 하겠습니다.설명에 앞서 그냥 강사님께서 하신 말씀처럼 외우는게 제일 나을수도 있습니다. 그냥 저처럼 이해하지 못하면 못 넘어가는 사람들을 위해 남깁니다.공변성과 반공변성에 대하여 매개변수와 리턴타입의 대입가능성에 대해 설명하고자 합니다. 강의에서 사용된 예제를 사용하겠습니다.function a(x: string | number): number{ return 0; } type B = (x: string) => number | string; let b: B = a; b("asdf") // B타입에 맞음 정상 b(123) //B타입에 맞지 않는 매개변수 이므로 //typescript가 오류를 잡아줄 수 있음먼저 매개변수에 대한 이야기입니다. 변수 b의 B 타입으로 정의되었습니다. 즉, 매개변수로는 x: string만 오도록 강제할 것입니다. 이는 b("asdf")로 사용했을 때 a("asdf")를 사용한 것과 같은 상황이니 문제가 없습니다. 하지만 반대면 어떨까요?function a(x: string): number{ return 0; } type B = (x: string | number) => number | string; let b: B = a; b("asdf") // 타입 B에 대해서도 정상 //a함수가 실행될때도 정상 b(123); // B타입상으로만 보면 정상임 //그러나 실제로 a함수가 실행될 때 오류 //따라서 이런 상황이 발생하지 않도록 //타입스크립트는 타입B에 함수 a를 할당할 수 없도록 함만약 이 상황이라면 변수 b는 B타입이기 때문에 매개변수로 number도 사용하능 합니다. 즉 타입상으로는 b(123)이 가능하다는 것이죠, 하지만 이 경우 a(123)이 실행되는 것과 같은데 a의 매개변수로는 string만 가능하기 때문에 문제가 발생합니다.정리하자면 실제로 대입된 함수의 매개변수가 허용하지 않는 타입을 넣으면 안 되기 때문에, (대입되는 함수의 매개변수)는 (타입의 매개변수)와 같거나 더 넓어야합니다.리턴값도 비슷한 원리입니다.function a(x: string | number): number{ return 0; } type B = (x: string) => number | string; let b: B = a; let result = b("asdf"); //result의 타입은 B타입에 의해 number|string 으로 추론됨 //실행결과 실제 타입은 number로 추론과 일치타입스크립트 입장에서 b("asdf")의 예상 결과는 number | string 이겠죠. b는 타입 B 니까요. 그리고 실제로 b("asdf")는 실제로 a("asdf")를 실행하는 것과 같으니 실제로는 number가 리턴됩니다. 타입스크립트는 number | string를 예상하고 있고, 거기에 number가 온 것이니 문제가 없습니다.반대 상황을 봅시다.function a(x: string | number): number | string { return 0; } type B = (x: string) => number; let b: B = a; let result = b("asdf"); //타입 B만 보고 추론하면 result는 number임 //근데 실제 실행결과로 result는 string이 될 수도 있음타입스크립트는 b("asdf")의 결과로 number 만을 기대할 것입니다. 근데 실제로 a("asdf")는 number | string 이에요. 그러면 원래는 b의 실행결과로는 number만 예상하고 있었는데 실제 결과로 number | string 이면 문제가 있겠죠?정리하자면 실제로 대입된 함수가 리턴한 값이 타입의 리턴값에 포함되지 않으면 안 되기 때문에, (대입되는 함수의 리턴값)는 (타입의 리턴값)와 같거나 더 좁아야합니다.위 모든 원칙은, 타입스크립트가 실제로 대입된 함수의 타입은 신경쓰지 않고, 현재 정의된 타입이 뭔지만 신경쓰기 위해서 존재한다고 생각하시면 이해가 편하실수도 있을 것 같네요... 타입스크립트의 타입검사기 입장에서 let b: B = a;이후에 b를 쓸 때, a에 대해서 신경1도 안쓰고 B에 대해서만 타입 검사를 해주려고 처음 대입할때 매개변수의 범위와 리턴값의 범위를 저렇게 제한했다고 보시면 된다는 뜻입니다.

안녕하세요.이글루스 블로그가 서비스를 종료해 글을 볼 수가 없어요.찾아보니 작성자가 다른 블로그에 글을 옮겨놓은것 같더라구요. 링크 수정하시면 좋을 것 같아요.https://www.donghyun53.net/ahb-%eb%8c%80%eb%b9%84-axi-%ed%94%84%eb%a1%9c%ed%86%a0%ec%bd%9c%ec%9d%98-%ec%9e%a5%ec%a0%90-%eb%aa%87-%ea%b0%80%ec%a7%80/

5번째 줄에 있는 문자열과, 7번째 줄에 있는 문자열은, 같은 문자열입니다.(당연히 같은 메모리 공간에 존재)이 부분에서 궁금한 점이 생겨 질문을 하게 되었습니다. 다른 문자열로 일일이 메모리에 저장하지 않고, 굳이 같은 문자열로 저장하는 이유가 있을까요?(제 추측으로는 속도 향상을 위해서 같습니다. 하지만 개발자가 같은 메모리에 위치한다는 사실을 잘 인지하지 못한다면 오류도 빈번히 발생할 것 같은데 이유가 궁금합니다.) 같은 문자열이 아닌 다른 문자열로, 즉 다른 메모리 공간에 각각 존재시키고 싶다면, 어떻게 해야할까요? 1번에서 '개발자가 같은 메모리에 위치한다는 사실을 잘 인지하지 못한다면 오류도 빈번히 발생할 것 같은데' 라고 제가 추측했었습니다. 실제로 이러한 예시가 있는지 궁금합니다.
