안녕하세요!   곶감 문제 코드에서 a[h-1]가 왜 행을 기준으로 되는지 궁금합니다 열을 기준으로 표현도 되지않나요? h=2일떄 2행이니 a[h-1]라고 표현하셨는데 a[h-1]이 2열을 표현할수도 있지않나요?   감사합니다

  import android.app.AlertDialogimport android.app.Dialogimport android.content.Contextimport android.content.DialogInterfaceimport android.os.Bundleimport android.util.Logimport androidx.fragment.app.DialogFragmentclass SubFragment : DialogFragment() { lateinit var mainActivity: MainActivity override fun onAttach(context: Context) { super.onAttach(context) mainActivity = activity as MainActivity Log.d("test", "3") } override fun onCreateDialog(savedInstanceState: Bundle?): Dialog { Log.d("test", "4") val builder = AlertDialog.Builder(mainActivity).setTitle("타이틀입니다.").setMessage("메시지입니다.") .setPositiveButton("수락") { dialogInterface: DialogInterface, i: Int -> mainActivity.binding.textView1.text = "Positive" }.setNeutralButton("Neutral") { dialogInterface: DialogInterface, i: Int -> mainActivity.binding.textView1.text = "Neutral" }.setNegativeButton("Negative") { dialogInterface: DialogInterface, i: Int -> mainActivity.binding.textView1.text = "Negative" } Log.d("test", "5") val alert = builder.create() Log.d("test", "6") return alert } 똑같이 따라쳤는데 mainActivity에 값이 들어가지 않더라구요 ... onAttach에서 값을 설정해주니까 잘 됩닏.

제가 아무래도 이해를 제대로 못한 것 같습니다. 2개로 나눠서 질문 드리겠습니다!   1. Member클래스가 있는데 하나로 통일하는 것이 아닌MemberForm클래스를 따로 왜 작성하는지 이해가 잘 안갑니다.  '데이터를 전달받을 폼 객체'라고 설명하시는데 이 부분에 대해 좀 더 자세하게 설명해주실수있을까요?   2.  웹 애플리케이션 계층 구조에서 도메인이 예제의 MemberForm 맞나요...?   답변 주시면 감사하겠습니다.

무엇이 원인인가요? 스택에서도 뚜렷한 답을 얻을수가 없네요;

다운로드는 했는데 실행을 어떻게 하는 건지 모르겠어요. cmd 그것도 따라했는데 탭 키 눌러도 자동완성 되지도 않고.. 백슬러쉬 하면 W가 나오는데 이것도 백슬러쉬래서 썼는데도..

강의를 듣다가 질문이 생겨서 질문드립니다.   빈 사이클에 대해서 살펴보면   스프링 컨테이너 생성 -> 스프링 빈 생성 -> 의존관계 주입 -> 초기화 콜백   -> 사용 -> 소멸전 콜백 -> 스프링 종료   이렇게 설명을 해주셨는데요..   제가 궁금했던 부분은 소스코드에서 의존관계 주입이 어느 부분이냐하는 것인데 다른 분들이 질문하신 것을 보면 setUrl은 의존관계 주입이 아닌 값 주입이라고 하시더라구요   그러면 강의에서의 소스코드에서는 의존관계 주입은 따로 하지 않은 것인가요??

안녕하세요 강사님 강의를 너무나도 재밌게 듣고 있는 학생입니다. 제가 윈도우 환경에서 하려다가 Ubuntu가 더 편해서 WSL를 사용해서 Ubuntu 환경에서 실습을 진행하고 있습니다. 그러던 중 애플리케이션 배포 -Docker Container 챕터에서 config-server를 도커 파일 만들고 배포하는 작업에서 에러가 발생합니다 문제는     docker run -d -p 8889:8889 --network ecommerce-network \ -e "spring.rabbitmq.host=rabbitmq" \ -e "spring.profiles.active=default" \ --name config-service youngkyonyou/config-service:1.0   (포트 8888 대신 8889를 사용함)   위 명령어를 -d 옵션을 빼고 실행해서 실행결과를 보여드리겠습니다.   여기까지 잘 실행되는 것 같으나 url로 접속할 때 문제가 생깁니다.   http://localhost:8889/ecommerce/default 로 접속하게 되면   위 사진과 같이 나오면서 로그가   /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v2.6.2) 2022-01-27 05:40:46.884 INFO 1 --- [ main] c.e.c.ConfigServiceApplication : The following profiles are active: default 2022-01-27 05:40:48.525 INFO 1 --- [ main] faultConfiguringBeanFactoryPostProcessor : No bean named 'errorChannel' has been explicitly defined.

비동기성은 순차적으로 실행되지 않는 것을 의미하고, 동시성은 switching해가며 한 번에 여러 작업을 하는 것으로 이해했습니다. 따라서 비동기성 예제로 보여주신 코루틴의 경우는 싱글 스레드에서 동시성을 구현한 것이라고 이해했습니다. 제가 궁금한 것은 비동기성은 항상 동시성인지, 그리고 동시성이면 항상 비동기성인지 입니다. (필요충분 관계인 것인지) (동시성이면서 동기성일 수도 있는건가요?) 만약 비동기성<->동시성 이 아니라면(필요충분 관계가 아니라면) 두 개념의 핵심적인 차이가 궁금합니다.

간단한 웹 게시판을 만들때 컨트롤러에서  논리 패스를 /member/join /member/login /member/logout  등 으로 @GetMapping @PostMapping으로  처리했었습니다.   근데 강의에서 보면 리소스만 식별하고 행위는 따로 구분하라 하셨는데요  그러면 논리패스를 /member 로만 설정하고 각 메서드(행위)에 맞는 Mapping으로(get,post,patch,put 등) 구현하는게 더 올바른 방법인가해서 질문드립니다.            

안녕하세요 해당 강의 실습 진행중에 인텔리제이 콘솔 부분에 한글이 깨져서 나오는데 어떻게 하면 정상적으로 나올 수 있을까요?  세팅- 파일 인코딩 - utf-8설정을 다 했는데도 이러네요 ㅠㅠ     늘 감사합니다.  

안녕하세요. 강의 관련이기도 하지만 조금 사이드 관련 질문이기도 한데요. 친절하게 답변해 주시면 감사드리겠습니다.   현재 살펴보고 계시는 중국 언리얼 서적 책을 보니 중국에도 많은 좋은 책들이 출판되고 있는 것 같습니다. 그렇다면 앞으로 중국에서 잘 쓰인 기술서적을 번역하여 수입해올 일도 점점 늘어날 것이라 생각하는데요. 현재 중국의 컴퓨터 프로그래밍 관련 책의 수준들이 어느정도인지 혹시 의견을 주실수 있으신가요?   (영어, 일본어, 한국어 책은 현재 어느정도 사전을 찾아가며 읽고 있어 제가 파악해 가고 있습니다.)   특히 중국은 해킹관련 기술이 많이 발달한 나라로 알고있는데 해킹관련 서적들은 좋은 책들이 중국에 더 많이 출판되는지, 중국에서 컴퓨터 관련 분야에서 출판되는 책들 중 질이 좋은 책들이 출판되는 분야를 알고싶습니다.  조금씩 중국어 공부를 하면서 번역해 보면서 읽고 싶어서요. ㅎㅎ   (예: 게임 클라이언트/서버 프로그래밍, 해킹/보안, AI, 운영체제, 컴파일러, 대용량 서버, DB 등...)

안녕하세요. 초보 개발자 명아주입니다.   궁금한게 있어서 문의드립니다. 제가 공부하다가 놓친걸 수도 있는데 아직 잘 이해가 안되는 부분이 하나 있습니다. 예를들어서   Member member = new Member(); member.setName("hello"); em.persist(member); member.setName("jpa");   이런 코드가 있을때 예상 : member가 영속성 컨텍스트에 들어감 트랜잭션 종료 때, flush할때 변경감지까지 포함해서 한 번의 쿼리만 나감 insert into member values (1, 'jpa'); 실제 : insert into member values (1, 'hello'); update member set name = 'jpa';   영속성 컨텍스트에 들어가있다가 아직 플러시 되지 않은 상태에서 변경되면 마지막에 변경된 사항으로 insert 한번만 나갈 줄 알았는데 실제 동작은 insert, 그리고 변경감지에 의한 update가 발생하더라구요.   저번에 말씀하셨던 것중 얼핏 기억나는 스냅샷? 같은 걸로 영속성에 들어간 상태를 스냅샷 찍어놓고 그거에 대한 insert 쿼리가 나가고 그 후에 변경감지를 처리하는건가요??   궁금합니다! 감사합니다.
