# 응용 애플리케이션

음.. 다른건 모르겠지만 코틀린 봐본김에\
<https://spring.io/guides/tutorials/spring-boot-kotlin/\\>
공식으로 제공해주고 있는 기본 SpringBoot + Gradle + Kotlin + Spring JPA로 구성<br>

하는건 일단 깃에 올리면서 하는게 맞는듯 : <https://github.com/kyu9/JPA-Book-Practice>

프로젝트의 설정에서\
groupId : 프로젝트 그룹명 artifactId : 프로젝트를 식별하는 아이디 version : 프로젝트 버전 name : 프로젝트 이름 packaging : 빌드, 패키징 방법

일단 application-properties를 제거하고 application.yml 으로 수정을 바꿔봤음<br>

```yaml
spring:
  datasource:
    driver-class-name: org.h2.Driver
    url: jdbc:h2:mem:testdb
    username: sa
    password:
  jpa:
    database-platform: H2
    hibernate:
      ddl-auto: create
    properties:
      hibernate:
        show_sql: true
        format_sql: true

logging:
  level:
    org.hibernate.sql: debug
```

<br>

swagger-ui를 여기를 참고\
<https://www.baeldung.com/kotlin/swagger-spring-rest-api\\>
<http://localhost:8080/swagger-ui/index.html> 여기에서 확인 가능!<br>

h2를 기본으로 사용할 예정\
<http://localhost:8080/h2-console> 로 접속!!\ <br>
