구상클래스에서 인터페이스 변수를 선언한 이유가 혹시 다형성과 관련이 있나요?

해결됨

나도코딩의 자바 기본편 - 풀코스 (20시간)

클래스의 상속과 관련된 다형성은 부모객체로 인스턴스를 생성하여 부모클래스의 메소드와 자식클래스 메소드 2가지를 업/다운캐스팅하여 자유롭게 호출할 수 있지만, 단일상속이라는 한계 때문에 다른 부모클래스의 메소드는 호출할 수가 없잖아요? 그래서 인터페이스가 존재하는 이유구요. 마찬가지로, 인스턴스를 생성할 때 다형성을 활용하여 인터페이스 객체(부모 객체)로 생성할 수는 있지만, 이것은 ISP(Interface Segregation Principle)원칙에 따라 detect(), report() 2개의 메소드를 호출하려면 Detectable, Reportable 객체 2개를 생성해야 하기 때문에 메모리가 효율적으로 관리되지 못하는거구요. 따라서 구상클래스인 FactoryCam에서 인터페이스 변수를 직접 생성하고 setter함수로 필요한 인터페이스 변수를 주입한 다음(Dependency Injection) , 주입당한 객체는 인터페이스에 의존하기 때문에(Reportable, Detectable) 동시에 기능이 다른 2가지 메소드를 호출할 수 있는거구요.(Dependency Inversion Principle) ... 과정을 이해하였지만 말로 풀어내니까 굉장히 장황하군요 사실 이 부분은 인터페이스 문법이라기보다는 디자인 패턴과 관련이 있지 않나싶습니다.

Next.js GCP App Engine 배포 시 환경변수 분기

미해결

Next.js로 Google Cloud Platform에 App Engine 서비스 배포를 진행하고 있습니다. 문제는 production ( 실 서비스 )와 development ( 개발용 )으로 나누어서 .env.development, .env.production의 두개의 환경변수를 가지고있습니다. 배포 시 실서비스 에서는 .env.production을 사용하도록 개발용 에서는 .env.development를 사용하도록 설정하려는데 이것저것 만져보아도 production만 사용하는 문제가 발생해버리네요. 현재 프로젝트구조와 설정코드는 이렇습니다. project ├── local └── Dockerfile └── docker-compose.yml ├── resource └── .next └── ... (Next.js 빌드 파일) └── node_modules └── package.json └── dev_app.yaml └── prd_app.yaml └── .env.development └── .env.production └── next.config.js └── ... (기타 Next.js 프로젝트 파일) 여기서 package.json의 script설정은 다음과 같습니다. { dev: "next dev", start: "next start", lint: "next lint", deploy: "npm run build && gcloud app deploy --project='production' -q --appyaml=prd_app.yaml", deploy:dev: "npm run build:dev && gcloud app deploy --project='development' -q --appyaml=dev_app.yaml", build: "dotenv -e .env.production next build", build:dev: "dotenv -e .env.development next build" } next.config.js는 특별히 건드리지 않았습니다. dev_app.yaml, prd_app.yaml파일은 서비스명만 각각 설정해 주었습니다. runtime: nodejs20 # or another supported version service: development 질문 1. 현재 app engine 업로드된 용량, 로직을 보니 빌드파일이 아닌 프로젝트 그대로 들어가는 것 같습니다. 빌드는 환경변수파일도 정상적으로 분기되는데 앱엔진에서 해당문제가 발생하는 것으로보아 혹시 Next.js에서 빌드된 파일로 app engine에 배포할 수 있는지 궁금합니다. 질문 2. 빌드파일만 올릴수 없다 라고 하더라도 프로젝트 그대로 올리면서 환경변수를 분기할 방법이 있는지 궁금합니다. 정말 문서건 블로그건 구글서칭, 깃허브검색, GPT 모두 끈질기게 시도해봤지만 능력부족 탓인지 성공하지 못했습니다.. 능력자분들께서 도움주시면 잊지않겠습니다!!
