+# 🌱 SPRING BOOT 세션2 실습
+
+## 1. 코드 파헤치기
+
+### 1.1 Entity 클래스에서 빌더 패턴 사용하기
+
+#### domain에서 Member 클래스 정의하기
+```java
+@Builder
+@Entity
+@NoArgsConstructor
+@AllArgsConstructor
+@Getter
+@EntityListeners(AuditingEntityListener.class)
+public class Member {
+    @Id
+    @GeneratedValue(strategy = GenerationType.IDENTITY)
+    @Column(name="member_id")
+    private Long id;
+
+    private String name;
+
+    private String email;
+
+    @CreatedDate
+    private LocalDateTime createdAt;
+}
+```
+
+#### 빌더 패턴 사용하여 service에 객체 생성 옵션 제공하기
+```java
+public Member createMember(MemberRequestDTO memberRequestDTO) {
+    Member member = Member.builder()
+          .name(memberRequestDTO.name())
+          .email(memberRequestDTO.email())
+          .build();
+
+    Member savedMember = memberRepository.save(member);
+    return savedMember;
+}
+```
+
+#### 빌더 패턴을 사용하는 이유
+- __불변성__ : setter를 사용하는 대신에, 빌더 패턴을 사용하여 객체를 불변으로 만들 수 있다. 상태가 변하지 않기 때문에 안전성을 보장한다.
+- __유연성__ : 필드의 종류와 순서를 선택적으로 유연하게 설정할 수 있다.
+
+---
+
+### 1.2 Controller로 클라이언트의 요청(url, 메소드) 매핑하고 처리하기
+
+#### @RequiredArgsConstructor 어노테이션 사용하기
+- Lombok 라이브러리에서 제공하며, 클래스 내의 final 필드를 초기화할 수 있는 생성자를 자동으로 생성한다.
+- final 필드로 선언된 의존성을 생성자를 통해 주입할 수 있게 된다.
+  - 스프링에서는 의존성 주입 시 생성자 주입을 권장한다!
+
+#### @RestController 어노테이션 사용하기
+- 스프링 프레임워크에서 주로 __RESTFUL__ 한 웹 서비스를 만들기 위해 사용한다.
+- 기본적으로 __Controller__ 역할을 하며 __JSON__ 이나 __XML__ 등의 데이터 형식을 반환하는 데 최적화된 기능을 제공한다.
+- 뷰를 반환하지 않고, JSON이나 XML 같은 데이터만을 반환한다.
+
+#### @RequestMapping("url명") 사용하여 url 매핑하기 + 
+#### @PostMapping, @GetMapping 사용하여 메소드 매핑하기
+```java
+@RequiredArgsConstructor
+@RestController
+@RequestMapping("/members")
+public class MemberController {
+
+    private final MemberService memberService;
+
+    @PostMapping
+    public ResponseEntity<?> createMember(@RequestBody MemberRequestDTO memberRequestDTO) {
+        Member member = memberService.createMember(memberRequestDTO);
+        return ResponseEntity.status(201).body(member);
+
+    }
+
+    @GetMapping
+    public ResponseEntity<?> getMemberList() {
+        try {
+            List<Member> response;
+            response = memberService.getMemberList();
+            if (response.isEmpty()) {
+                return ResponseEntity.status(200).body("사용자가 존재하지 않습니다.");
+            }
+            return ResponseEntity.ok(response);
+        } catch(Exception e) {
+            return ResponseEntity.status(500).body("서버 내부 에러");
+        }
+    }
+}
+```
+
+---
+
+### 1.3 JpaRepository 사용하기
+
+#### JPA는 뭘까?
+- __JPA__ 는 자바 객체와 데이터베이스 테이블 사이의 매핑을 정의하고, 데이터베이스의 데이터를 객체로 다루는 방법을 제공하는 ORM 표준
+- SQL 없이도 데이터베이스의 데이터를 다룰 수 있게 해준다.
+
+#### JpaRepository는 뭘까?
+- JPA에서 제공하는 기본적인 CRUD 작업과 데이터베이스 쿼리를 처리할 수 있는 Repository 인터페이스
+- 기본 CRUD 작업 기능
+  - save(), findById(), deleteById(), ...
+- 페이징 및 정렬
+  - findAll(Pageable pageable)
+- 사용자 정의 쿼리 메소드
+  - 사용자가 선언한 메소드에 대해 자동으로 해당 조건에 맞는 SQL 쿼리를 생성한다.
+
+#### JpaRepository 상속받기
+```java
+@Repository
+public interface MemberRepository extends JpaRepository<Member, Long> {
+}
+```
+
+- 이 레포지토리가 관리하는 entity 클래스인 Member의 PK 타입이 Long으로 설정한다는 의미이다.
+- __JpaRepository__ 를 상속받았으므로 별도의 구현 없이 기본적인 CRUD 작업 사용 가능하다.
+
+---
+
+### 1.4 DTO 사용하기
+
+#### DTO는 뭘까?
+- Data Transfer Object의 약자로, 데이터를 전송하고 관리하는 역할을 한다.
+- 주로 데이터 계층과 애플리케이션의 다른 계층 간에 데이터를 전송할 때 사용된다.
+- 데이터 유효성 검사와 변환을 중앙 집중화하여 일관된 방식으로 데이터를 처리할 수 있게 한다.
+
+#### Record를 사용하여 DTO 정의하기
+```java
+public record MemberRequestDTO(String name, String email) {
+}
+```
+
+- name과 email 필드를 가진 Record를 생성하며, Record 클래스를 통해 DTO를 정의하고 있다.
+- DTO 객체를 정의하면서 자동으로 필요한 메소드들을 생성한다. 
+
+---
+
+## 2. 코드 구현 도중 있었던 이슈
+
+### 2.1 h2 데이터베이스 실행
+- 윈도우 h2 실행 커맨드는 __h2.bat__
+- H2\bin\ 디렉토리 들어가서 h2.bat 입력
+
+### 2.2 ⚠️Response Body의 createdAt 필드가 null로 반환되는 문제⚠️
+- __LocalDateTime__ 사용할 때는 __main__ 클래스에서 __@EnableJpaAuditing__ 어노테이션 추가해줘야 한다!
+  ```java
+  public class Member {
+    @Id
+    @GeneratedValue(strategy = GenerationType.IDENTITY)
+    @Column(name="member_id")
+    private Long id;
+
+    private String name;
+
+    private String email;
+
+    @CreatedDate
+    private LocalDateTime createdAt;
+  }
+  ```
+
+  ```java
+  import org.springframework.data.jpa.repository.config.EnableJpaAuditing;
+
+  @EnableJpaAuditing
+  public class DemoApplication {
+
+	  public static void main(String[] args) {
+		  SpringApplication.run(DemoApplication.class, args);
+	  }
+  }
+  ```
+

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       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
