이전 강의에서 서블릿과 jsp 각각의 비효율적인 부분 때문에 MVC 패턴이 등장하게 된 것으로 이해를 했습니다. MVC 패턴이 동작하기 위해서는 RequestDispatcher 를 통하여 jsp 부분으로 forwarding 해주는 기능이 필수적으로 필요해 보이는데요. 이 기능이 서블릿의 단점을 보완하기 위해 서블릿 버전이 업데이트 되면서 MVC 를 지원하기 위해 나중에 나온 기능인지, 원래 부터 있었던 기능인데, "고대 개발자"들이 모르고 비효율적으로 쓰고 있었던 건지 궁금합니다.

허나 강의를 촬영하신 시기와 지금의 차이가 있어서 그런지 강의 내용보다 버전차이에서 오는 다름을 찾는 것이 더욱 어려웠던 강의입니다. 그래서 강사님의 깃 중 https://github.com/jaewonhimnae/boiler-plate-ko을 클론하여 완벽히 돌아가는 상태를 보려고 하는데 config폴더에 dev.js를 잘 넣고 맞는 디렉토리에서 npm install을 하였습니다. 하지만 이리저리 시도를 해봐도 npm install에서 다량의 오류가 발생하여 답답해하던 중 여기에 질문을 올려봅니다.  ero@Kimui-MacBookAir:~/Downloads/boiler-plate-ko-master » npm install   > bcrypt@3.0.7 install /Users/ero/Downloads/boiler-plate-ko-master/node_modules/bcrypt > node-pre-gyp install --fallback-to-build   node-pre-gyp WARN Using needle for node-pre-gyp https download node-pre-gyp WARN Tried to download(404): https://github.com/kelektiv/node.bcrypt.js/releases/download/v3.0.7/bcrypt_lib-v3.0.7-node-v83-darwin-x64-unknown.tar.gz node-pre-gyp WARN Pre-built binaries not found for bcrypt@3.0.7 and node@14.18.1 (node-v83 ABI, unknown) (falling back to source compile with node-gyp) No receipt for 'com.apple.pkg.CLTools_Executables' found at '/'.   No receipt for 'com.apple.pkg.DeveloperToolsCLILeo' found at '/'.   No receipt for 'com.apple.pkg.DeveloperToolsCLI' found at '/'.   gyp: No Xcode or CLT version detected! gyp ERR! configure error gyp ERR! stack Error: `gyp` failed with exit code: 1 gyp ERR! stack     at ChildProcess.onCpExit (/usr/local/lib/node_modules/npm/node_modules/node-gyp/lib/configure.js:351:16) gyp ERR! stack     at ChildProcess.emit (events.js:400:28) gyp ERR! stack     at Process.ChildProcess._handle.onexit (internal/child_process.js:282:12) gyp ERR!

일반 데스크탑화면일때 뷰량 모바일일때 뷰량 헤더부분(네비게이션) 을 다르게 구성해서 모바일로 가면 화면을 다른걸로 보여줘야되는데 어떻게 해야되나요?

a instanceof Promise ? a.then(a=> f(acc,a), e=> e == nop ? acc : Promise.reject(e)) reduceF함수 내부에서 e => e== nop이라면 acc를 반환하기로 되어있는데, 쉼표를 하고 e가 nop과 같은지 검사하는 이유는 앞에 a=>f(acc,a)가 실패했을 때 호출이 되고 이것이 nop인지 아니면 함수 전체를 reject하려고하는 건지를 확인하려는 의미인 것인가요?  그리고 위의 코드에서 nop은 Lfilter로 부터 전달된 게 맞나요?

예를들면 UserSimpleDto 클래스로 id, name, joinDate만 내려주고 전체 데이터는 User에서 가져오는 방식은 문제가 있을까요? 제가 rest api를 처음 제대로 접해봐서 뜬금없는 질문인것 같긴한데 궁금해서 질문드립니다. 

오류로 지금까지 작성했던게 안보이네요 이유가 뭘까요?

  강의를 따라하면서 편집 할때도 동일한 에러가 나서 신택스 에러라길래 원래의 파일대로 빌드 해도 같은 에러가 반복됩니다...

  안녕하세요, 항상 양질의 답글 감사드립니다. 이번 강의를 들으면서 싱글톤 스코프, 프로토타입 스코프를 같이 사용할 때 발생하는 일이 정확히 어떤지 궁금해서 문의드립니다.   public class SingletonTypeTestWithProtoTyepBean { @Test void prototypeTest(){ AnnotationConfigApplicationContext ac = new AnnotationConfigApplicationContext(PrototypeBean.class); PrototypeBean prototypeBean1 = ac.getBean(PrototypeBean.class); PrototypeBean prototypeBean2 = ac.getBean(PrototypeBean.class); prototypeBean1.addCount(); prototypeBean2.addCount(); System.out.println("prototypeBean2.getCount() = " + prototypeBean2.getCount()); System.out.println("prototypeBean1.getCount() = " + prototypeBean1.getCount()); Assertions.assertThat(prototypeBean1.getCount()).isEqualTo(prototypeBean2.getCount()); } @Test void SingletonTestWithProto(){ AnnotationConfigApplicationContext ac = new AnnotationConfigApplicationContext(ClientBean.class, PrototypeBean.class); ClientBean bean1 = ac.getBean(ClientBean.class); ClientBean bean2 = ac.getBean(ClientBean.class); int count1 = bean1.logic(); int count2 = bean2.logic(); System.out.println("count1 = " + count1); System.out.println("count2 = " + count2); Assertions.assertThat(count1).isNotEqualTo(count2); ac.close(); } @RequiredArgsConstructor @Scope("singleton") static class ClientBean{ private final PrototypeBean prototypeBean; public int logic(){ prototypeBean.addCount(); return prototypeBean.getCount(); } @PostConstruct public void initSingleton(){ System.out.println("ClientBean.initSingleton"); } @PreDestroy public void singltonend(){ System.out.println("ClientBean.singltonend"); } } @Scope("prototype") static class PrototypeBean { private int count = 0 ; public void addCount() { count++; } public int getCount(){ return count; } @PostConstruct public void init(){ System.out.println("PrototypeBean.init"); } @PreDestroy public void destory(){ System.out.println("PrototypeBean.destory"); } }} 위 코드의 실행 결과는 아래와 같습니다. 코드 실행 결과를 바탕으로 실행 과정을 유추해보면 다음과 같은 것 같은데, 제가 생각하는 것이 맞는지 한번 알려주실 수 있을까요?   1. 스프링 컨테이너 생성과 함께 클라이언트 클래스의 빈 객체는 생성된다. 2. 클라이언트 클래스의 빈 객체는 생성자 주입을 통해서 되기 때문에, 생성되는 시점에서 프로토타입 클래스 빈 객체를 호출한다 3. 이 때 프로토타입 빈 객체는 생성되고, 의존관계 주입되고, 초기화 메서드까지 진행되고 스프링 컨테이너에 저장된다. (프로토타입 초기화 메서드 실행 로그 확인) 4. 스프링 컨테이너에서 프로토타입 빈 객체를 찾아와 클라이언트 클래스 빈 객체에 주입시켜준다. 이 때 스프링 컨테이너에서 프로토타입 빈 객체는 사라진다. 5. DI 단계는 이미 완료되었으며, 클라이언트 초기화 메서드 실행됨.  위의 단계로 진행되는 것이 맞을까요? 앞에 설명해주신 내용을 좀 더 생각해봐서 위와 같이 정리했는데... 뇌피셜로는 맞는 것 같은데, 정말로 맞을지 궁금합니다. 항상 감사드립니다.

기본적인 아이디어는 걍 각 막대기마다 가지고 있는 레이저의 개수를 기록하자 이게 다임   function solution(s){     let a = s.split('');     let laser = sum = originPos = 0;     let stack = [];     for(let i=0; i<s.length; ++i) {           if(a[i] === '(' && a[i+1] === '(') {             originPos = i;             do {                 if(a[i] === '(') sum++;                 else sum--;                 if(a[i] === '(' && a[i+1] === ')')                     laser++;                 ++i;             } while (sum !== 0);             i = originPos;             stack.push([i,laser+1]);             sum = laser = 0;         }     }     sum = stack.reduce((acc,v)=>{return acc + v[1];},0)     return sum; } let b ='(((()())(())()))'; let a="()(((()())(())()))(())"; console.log(solution(a));

해당 영상에 소리가 너무 작게 들리는 것 같아서  게시판에 글 남깁니다. 확인 부탁드려요~

스택 안쓰고 괄호를 카운트해서 다음과 같이 해도 될까요? function solution(s) { let answer = "YES"; let cnt = 0; for (let i of s) { if (i === "(") cnt++; if (i === ")") cnt--; if (cnt < 0) return "NO"; } if (cnt !== 0) { return "NO"; } return answer; } let a = "(()(()))(()"; console.log(solution(a));

선생님~! 예를들어 계단 3번까지 오를때는   1번에서 3번을 갈때 바닥에서 1번까지 가는 경우의수는 1개이지만, 1번에서 3번까지 가는 방법은 1->2->3 한칸씩 이동하는 방법 한개와 1->3 두칸 이동해서 한번에 가는 방법 한개 이렇게해서 1번에서 3번까지 가는 방법이 총 두개가 되지 않나요?
