+# 🏷️WEEK 2 회원 관리 예제, 스프링 빈과 의존 관계
+[스프링 입문 - 코드로 배우는 스프링 부트] 섹션 4-5을 수강하고 TIL을 작성하였습니다.
+## 🔎 회원 관리 예제 - 백엔드 개발
+### 1️⃣ 비즈니스 요구사항 정리
+---------------------
+데이터: 회원ID, 이름 / 기능: 회원 등록, 조회
+![일반적인 웹 애플리케이션 구조](https://github.com/user-attachments/assets/204e3b0c-62b5-4391-a4df-4207910669df)
+
+![인터페이스, 데이터 저장소](https://github.com/user-attachments/assets/bd7fe7d6-7da1-41ba-94c1-980f5063ca27)
+
+### 2️⃣ 회원 도메인과 리포지토리 만들기
+-----------------------
+src/main/java/hello.yunakang 에 `domain` 패키지 생성 → 그 안에 `Member` 클래스 생성
+
+
+또한, hello.yunakang 안에 `repository` 패키지 생성 → 그 안에 class로 하는데 `MemberRepository` 인터페이스로 생성
+
+`Optional` ; java 8에 들어감, null 처리 방식 다룸
+
+repository 패키지 안에 `MemoryMemberRepository` 클래스 생성
+
+### 3️⃣ 회원 리포지토리 테스트 케이스 작성
+--------------------------
+테스트 시, 자바의 main 메서드를 통해 실행 or 웹 애플리케이션의 컨트롤러를 통해 해당 기능을 실행.
+
+<= 준비하고 실행하는데 오래 걸리고, 반복 실행하기 어렵고 여러 테스트를 한번에 실행하기 어려움.
+
+⇒ 자바는 `JUnit`이라는 프레임워크로 테스트를 실행하며 문제 해결!!
+
+test/hello.hellospring에 `repository` 패키지 생성 ⇒ 그 안에 `MemoryMemberRepositoryTest` 클래스 생성
+
+`get()` : Optional 쓸 때 값 꺼내는 함수, 좋은 방법은 x
+
+test별로 돌릴 수도 있고, 전체 다 test 돌릴 수 o
+
+but, 모든 test는 순서가 정해져 있지 x ⇒ 순서에 의존적이면 x,
+
+`afterEach()` 실행 : test 끝날 때마다 실행, 여기서는 메모리 DB에 저장된 데이터를 삭제한다.
+
+**정상 출력**
+![정상 출력](https://github.com/user-attachments/assets/3dfcfdc8-bb2c-4323-bc5c-cfbff5d7b04e)
+
+**코드 순서 의존적이어서 나타나는 error**
+![코드 순서 의존적이어서 나타난 에러](https://github.com/user-attachments/assets/b3e60554-6041-4165-89a9-6c5938d4116b)
+
+**error 수정 후 전체 test 돌리기**
+![전체 test 돌리기](https://github.com/user-attachments/assets/54ba1345-931b-44b3-8426-dbd840d1af3d)
+
+### 4️⃣ 회원 서비스 개발
+main/java/hello.yunakang에서 `service`  패키지 생성 ⇒ 그 안에 `MemberService` 클래스 생성
+
+ctrl + t로 따로 메서드 뽑아내기 `validateDuplicateMember` 함수 뽑아내기
+
+**⇒ service는 용어가 비즈니스 방향, repository는 비교적 개발자 친화적인 용어**
+
+### 5️⃣ 회원 서비스 테스트
+class 가리키고, `alt+enter` ⇒ CREATE new test
+
+testing library : Junit5 밑에 함수 다 체크!
+
+test 함수명은 한글로 적어도 됨!
+
+test 코드 작성 시 given, when, then(검증) 주석 많이 사용, test는 정상 flow보다 예외 flow가 더 중요함
+
+중복_회원_예외 함수에서 try-catch문 잘 쓰지 x
+
+`@BeforeEach`: 각 테스트 실행 전에 호출된다.
+
+테스트가 서로 영향이 없도록 항상 새로운 객체를 생성하고, 의존관계도 새로 맺어준다 + `@AfterEach` 도 추가해주기
+
+**회원 서비스 테스트**

+
+
+## 🌱스프링 빈과 의존 관계
+### 1️⃣ 컴포넌트 스캔과 자동 의존 관계 설정
+---------------------
+main/java/hello.yunakang/controller에서 `MemberController` class 생성
+
+`MemberService`에서 **@Service, @Autowired** 넣어주고, `MemoryMemberRepository`에서는 **@Repository** 넣어주기
+
+**컴포넌트 스캔 코드 추가 이후 실행 확인**
+![코드 추가 이후 실행 확인](https://github.com/user-attachments/assets/13e4a140-ef92-41da-9b97-151382fb12f5)
+
+
+**<스프링 빈을 등록하는 2가지 방법>**
+
+** 스프링 빈 등록 이미지**
+![스프링 빈 등록 이미지](https://github.com/user-attachments/assets/ed7289d1-1683-4be0-8ec8-4f9a8fe17dac)
+
+- 컴포넌트 스캔(위의 방법처럼 @ 사용하는 방법)⇒ 자동 의존관계 설정
+- 자바 코드로 직접 스프링 빈 등록하기
+
+  **<컴포넌트 스캔 원리>**
+    - @Component 있으면 스프링 빈으로 자동 등록된다.
+    - @Controller 컨트롤러가 스프링 빈으로 자동 등록된 이유도 컴포넌트 스캔 때문이다.
+    - @Component를 포함하는 다음 애노테이션도 스프링 빈으로 자동 등록된다.
+        - @Controller
+        - @Service
+        - @Repository
+
+  스프링은 스프링 컨테이너에 스프링 빈을 등록할 때, 기본으로 **싱글톤으로 등록**(유일하게하나만 등록해서 공유)
+
+  따라서 같은 스프링 빈이면 모두 같은 인스턴스! 설정으로 싱글톤이 아니게 설정할 수 있지만, 특별한 경우를 제외하면 대부분 싱글톤을 사용
+
+
+### 2️⃣ 자바 코드로 직접 스프링 빈 등록하기
+---------------------------
+회원 서비스와 회원 리포지토리의 @Service, @Repository, @Autowired 애노테이션을 제거하고 진행
+
+1. memberservice와 memorymemberrepository에서도 애노테이션 다 제거
+2. main/java/hello.yunakang에서 `SpringConfig` 클래스 추가
+3. 실행해보기
+
+**실행 결과**
+![실행 결과](https://github.com/user-attachments/assets/28776789-e27c-4777-993e-188bdd05cdb9)
+
+DI(dependency Injection) 에는 필드 주입, setter 주입, 생성자 주입 이렇게 3가지 방법이 존재 의존 관계가 실행중에 동적으로 변하는 경우는 거의 없으므로 **생성자 주입을 권장!!**
+
+← setter 주입으로 하는 경우, public으로 열려 있어야 하는데 훼손될 가능성 o
+
+실무에서는 주로 정형화된 컨트롤러, 서비스, 리포지토리 같은 코드는 컴포넌트 스캔을 사용, 그리고 정형화 되지 않거나, 상황에 따라 구현 클래스를 변경해야 하면 설정을 통해 스프링 빈으로 등록; 직접 설정 파일을 가질 때의 장점!

+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
