[코드캠프] 부트캠프에서 만든 고농축 백엔드 코스
따라하고있는데 Connection부분이 저렇게 줄이 찍 가져있고 사용되지않음으로 표시된다고 뜹니다. import부분도 그렇구요. 무엇때문에 이럴까요?

코딩으로 학습하는 리팩토링
안녕하세요 강사님 레코드 캡슐화 설명을 들으면서 궁금한 점이 생겨 질문 드립니다. 강의에서, 퍼블릭 필드를 감추는 용도로 퍼블릭 메서드를 사용할 수 있는데, 그 이유로는 퍼블릭 필드(ex, String name) 와 퍼블릭 메서드(ex, String setLastName()) 의 이름이 완전히 동일하다는 보장이 없기 때문입니다. 위 문장을, 퍼블릭 메서드는 퍼블릭 필드를 감추는 용도로 사용할 수 있다고 이해했습니다. 궁금한 점은, 그렇다면 필드를 감추는 것이 중요한 이유는 클라이언트단에서 데이터 클래스의 필드에 무작위적인 접근을 방지하기 위함인가요? 무작위적인 필드의 접근은 데이터를 쉽게 수정할 수 있게 때문이라고 추측했습니다. 감사합니다.

실전! 스프링 부트와 JPA 활용1 - 웹 애플리케이션 개발
JPA와 DB 설정, 동작확인의 테스트코드를 실행하는 중 오류가 나서 질문 드립니다. 가끔 jpashop.mv .db를 삭제 후 처음부터 생성을 다시하면 첫 테스트 실행시에는 에러가 나지 않을때가 있으나, 두번째 실행부터는 같은 오류가 다시 반복됩니다. Rollback(false)를 사용하지 않아도 콘솔창에서 롤백한다는 메시지도 나오지 않았습니다. MVCC=true 부분도 삭제해봤고, application.yml이랑 build.gradle도 여러번 확인했습니다. MemberRepository 입니다. Member 클래스 입니다. 오류가 나는 테스트코드 입니다. 처음 생성시 Junit4로 만들었습니다. application.yml 입니다. build.gradle 입니다. h2는 실행중이며, 1.4.200 버전 입니다. 강의자료에서 해당 버전 사용하라고 명시되어 있어 다른 버전으로는 사용해보지 않았습니다. 아래는 오류 전문입니다.

스프링 시큐리티 OAuth2
KeyCloak 을 인가서버로 활용하고 Resource 자원 사용하는 Data API 인가 처리를 하는 Auth API (Gateway) 를 구현해서 진행하고 있습니다. 그런데 너무 여러가지 방식이 많다보니 혼돈이 와서 선생님이 가르쳐주신 방식으로 인가와 인증을 구현하려고하는데, 인가 서버 -> KeyCloak 사용 게이트 웨이에 Oauth2 를 넣으려고 하는데 개념적으로 궁금한 점이 있어 여쭤봅니다. 공개 클라이언트 방식과 기밀 클라이언트 가 구현함에 있어 어떤 차이를 가지는지 의문입니다. 가령 react -> KeyCloak 요청 시 token 을 바로 가져오려고 하는데, 이 토큰을 받는 것 까진 문제가 없습니다. 하지만 영상에서 보여주신 것과 같이 자원 API 로 접근하는 권한을 획득하기 위해서 기밀 클라이언트 방식으로 구현하면 code 를 리다이렉트 받은 uri 와 token 요청시 리다이렉트 uri 가 같아야하는 문제가 있어서 code 를 auth api 로 받은 뒤 토큰 엔드포인트를 찍어 스프링 프로젝트에서 가져올 때 오류가 발생합니다. react -> keycloak -> code 반환 받은 것 -> spring -> redirect uri 문제로 토큰 발급 불가 가 되는데 어떤 형식으로 처리해야 맞는 것인지 궁금합니다.

나도코딩의 자바 기본편 - 풀코스 (20시간)
안녕하세요 챕터 6 부분을 공부하고 있는데 void를 쓰는 경우와 안쓰는 경우의 차이가 잘 와닫지 않습니다. 리턴값이 없으면 void를 쓰고, 리턴값이 있으면 void를 안쓴다고 알고 있는데 리턴값부터 이해가 잘 가지 않네요! 예를 들어서 // 호텔 주소 public static String getAdress() { return "서울시 어딘가"; } 과 셋째 줄에 sout "서울시 어딘가" 를 쓰는 것은 무엇이 다른건지요? 감사합니다 :)

[코드캠프] 부트캠프에서 만든 고농축 백엔드 코스
안녕하세요. 제가 찾고 기다리던 내용의 강의라 매우 만족하며 수강하고 있는 수강생입니다! ㅎ products.service.ts 파일에서 create와 update 메서드 작성할 때 typescript 에러에 대해 질문드립니다. products.service.ts 파일 create 메서드에서 productTags를 등록하는 과정에 const result2 = [] 부분을 const result2: string[]로 작성하면 await productRepository.save (...) 에서 No overload matches this call이 뜨고 update 메서드에서 updateProductInput에 UpdateProductInput로 타입을 지정하면 위와 마찬가지로 await productRepository.save (newProduct)에서 No overload matches this call이 뜹니다. 두 경우 모두 Type 'string' is not assignable to type 'ProductTag' 문제로 product.entity.ts에서는 productTag를 아래와 같이 등록하고 @Field(() => [ProductTag]) @JoinTable() @ManyToMany(() => ProductTag, (productTags) => productTags.products) productTags: ProductTag[]; createProduct.input.ts에서는 CreateProductInput에서 productTag를 아래와 같이 등록해서 발생하는 문제라고 추측했습니다. @Field(() => [String]) productTags: string[]; 두 경우 모두 타입을 지정하지 않고 any로 두면 문제는 사라지긴 합니다. any로 두고 사용할 수밖에 없는 것인지 아니면 타입 지정을 해서 사용하는 방법이 있는지 궁금합니다.

yarn start:dev 실행 하고 나면 아래와 같이 나오면서 에러가 뜨고 있어요 ERROR [TypeOrmModule] Unable to connect to the database. Retrying (1)... 아래 코드도 정상적으로 기입 했는데, 계속 접속 오류로 연결이 되지가 않습니다. import { ApolloDriver, ApolloDriverConfig } from '@nestjs/apollo' import { Module } from '@nestjs/common' import { GraphQLModule } from '@nestjs/graphql' import { TypeOrmModule } from '@nestjs/typeorm' import { BoardsModule } from './apis/boards/boards.module' import { Board } from './apis/boards/entities/board.entity' @Module({ imports: [ BoardsModule, GraphQLModule.forRoot<ApolloDriverConfig>({ driver: ApolloDriver, autoSchemaFile: 'src/commons/graphql/schema.gql', }), TypeOrmModule.forRoot({ type: 'mysql', host: 'localhost', port: 3306, username: 'root', password: 'test1234', database: 'myproject03', entities: [Board], synchronize: true, logging: true, }), ], // controllers: [AppController], // providers: [AppService], }) export class AppModule {} 현재 brew 확인시 Mysql 서버도 정상적으로 켜져 있는것을 확인 할 수 있어요 디비버에서도myproject03 이라고 정확하게 만들었습니다. 선생님의 강의하고 다른부분을 못 찾았는데, 데이터 베이스가 연결이 안될 때는 어느부분을 더 점검 해 봐야 할지요?

실전! 스프링 부트와 JPA 활용1 - 웹 애플리케이션 개발
안녕하세요 영한님 강의 잘 듣고 있습니다^^ 전부터 궁금해 왔던 것인데요, 팩토리를 만들 때 정적으로 올리는 이유에 대해서 궁금합니다 영한님이 다른 QnA에서 추천해 주신 내용들을 읽어보았으나 굳이 왜 "정적"영역으로 보내는 가에 대한 의문은 쉽게 풀리지 않습니다 ㅜㅜ 일단 정적 팩토리 메서드로 보내면 생성자들에 대한 응집도가 크게 떨어지는 느낌입니다. "엘레강트 오브젝트"라는 책을 보면 생성자는 10~15개 까지도 만들고 퍼블릭 메서드를 최대한 적게 가져가라고 가이드를 주는데요, 정적 영역으로 보내면 주/부 생성자로 보낼 수 없기 때문에 그 많은 생성자들이 다 흩어지고, 생성자들 간 관계를 맺을 수 없기 때문에 유연성이 떨어지고 코드 중복이 자주 일어나는 효과가 나는 것 같습니다 이는 굳이 정적 영역으로 보내지 않고 주/부 생성자로 구분하면 쉽게 해결될 일이 아닌가? 하는 생각도 들어 질문을 드립니다

http://localhost:3000/graphql 실행 후 query > getHello 시 오류가 있습니다. 코드는 오타 없이 동일 한데, 저는 실행시 http://localhost:3000/graphql 여기서 아래와 같은 오류가 뜨는데 어떤 상황인지 파악이 잘 되지가 않습니다. { "errors": [ { "message": "Cannot return null for non-nullable field Query.getHello.", "locations": [ { "line": 2, "column": 3 } ], "path": [ "getHello" ], "extensions": { "code": "INTERNAL_SERVER_ERROR", "exception": { "stacktrace": [ "Error: Cannot return null for non-nullable field Query.getHello.", " at completeValue (/Users/back/study/20230119_nestjs/class/13-01-nestjs-with-graphql/node_modules/graphql/execution/execute.js:594:13)", " at /Users/back/study/20230119_nestjs/class/13-01-nestjs-with-graphql/node_modules/graphql/execution/execute.js:486:9", " at processTicksAndRejections (node:internal/process/task_queues:95:5)", " at async Promise.all (index 0)", " at execute (/Users/back/study/20230119_nestjs/class/13-01-nestjs-with-graphql/node_modules/apollo-server-core/src/requestPipeline.ts:501:14)", " at processGraphQLRequest (/Users/back/study/20230119_nestjs/class/13-01-nestjs-with-graphql/node_modules/apollo-server-core/src/requestPipeline.ts:407:22)", " at processHTTPRequest (/Users/back/study/20230119_nestjs/class/13-01-nestjs-with-graphql/node_modules/apollo-server-core/src/runHttpQuery.ts:436:24)" ] } } } ], "data": null } app.module.ts 에도 정상적으로 연결 해 두었습니다. import { Module } from '@nestjs/common' // import { AppController } from './app.controller'; // import { AppService } from './app.service'; import { BoardsModule } from './apis/boards/boards.module' import { GraphQLModule } from '@nestjs/graphql' import { ApolloDriver, ApolloDriverConfig } from '@nestjs/apollo' @Module({ imports: [ BoardsModule, GraphQLModule.forRoot<ApolloDriverConfig>({ driver: ApolloDriver, autoSchemaFile: 'src/commons/graphql/schema.gql', }), ], // controllers: [AppController], // providers: [AppService], }) export class AppModule {}

(예/아니오) [질문 내용] 일대다[1:N] 강의의 16분 29초 쯤에 연관관계의 주인이 양쪽에 모두 있으면 망한다라는 언급이 있으신데, 순서가 꼬이거나 예측이 안된다는게 구체적으로 어떤 의미인지 예시가 있을까요? 정말 단순하게 생각하면 어쨋든 연관관계의 주인이 아닌 쪽에서 mappedby를 통해 읽기 전용으로 설정하지 않아도 Member에서 추가하나 Team에서 추가하나 반영될 수 있다면 오히려 좋지 않나 싶은 의구심이 들어서 질문드립니다 감사합니다 :)

따라하며 배우는 NestJS
#7-2 회원가입 기능구현에서 강의 내용 전체 작성 후 회원가입 진행하였는데, username과 password가 컨트롤러에서 console.log(authCredentialDto)를 찍으니 빈 객체만 내뱉고 있고 db에 정상적으로 저장이 되지 않았습니다. 이리저리 코드를 수정해보니. dto 구성 단게에서 validator import 후에 정상적으로 출력이 됩니다. 강의 영상에서는 문제 없이 되던데 왜 이렇게 되는지 궁금합니다.

안녕하세요, 우선 2023년도 버전 강의 업데이트에 감사하다는 말씀부터 드리고 싶습니다. 2022년도 버전만큼을 새로 찍어서 올려주시다니... 새해부터 마음이 뜨끈해지네요. 다른게 아니라, 언뜻 보기엔 섹션 6(prisma 쿼리 알아보기)이 Prisma에 대한 기본적인 개념을 잡는 섹션으로 보이는데 2023년도 강의 버전이 업데이트되면서 우선 PG실습부터 하는 순서로 변경된 것 같습니다. 이게 강사님께서 의도하시고, 또 추천하시는 수강 순서가 맞는지 궁금합니다!

스프링 입문 - 코드로 배우는 스프링 부트, 웹 MVC, DB 접근 기술
스프링 강의 선행으로 요구되는 지식이 자바, 관계형 데이터베이스 기초라고 되어 있는데요 자바랑 MySQL은 공부했습니다. 그런데 JDBC나 JSP, 서블릿, 디자인 패턴 등에 대한 지식이나 웹 개발에 대한 지식은 모른 채로 로드맵 시작해도 상관없나요?

[질문 템플릿] 1. 강의 내용과 관련된 질문인가요? 예 2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? 잘모르겠습니다 ㅎㅎ.. 3. 질문 잘하기 메뉴얼을 읽어보셨나요? 예 [질문 내용] 1. 데이터 삽입 순서 관련 질문 서버가 여러 대 있다고 가정했을 때, 각 서버에 하단의 이미지처럼 메모리에 50개씩 값을 올려둘 경우, DB에 들어가는 데이터가 순차적으로 안들어가지 않나요? 구체적으로 생각해보지는 않았지만, 순차적으로 데이터가 들어가지 않을 경우에 대한 이슈가 있지 않을까 싶어서 질문드립니다! 2. 중간에 비어있는 구간 관련 질문 위와 마찬가지로 서버가 여러 대 있고 각 서버마다 50개씩 메모리에 할당했다고 가정했을 때, 특정 서버가 죽게되면 죽은 서버의 메모리가 가지고있던 개수만큼의 공백이 생기지 않나요? (거의 그럴 일은 없겠지만) 서버가 시도때도없이 다운될 경우 아무리 Long 타입을 지정했음에도 수가 넘어가는 케이스가 생기지 않을까 싶습니다.
