포스트 목적: 스프링 부트와 AWS로 혼자 구현하는 웹 서비스 3장 따라하기
데이터베이스만 책이랑 다르게 해봄. 그래서 개삽질중... 책 내용은 좋은데 내가
설정을 다르게 해서 삽질중이기도 하고, 책에 오타가 많다 ㅋㅋㅋㅋㅋㅋㅋㅋ
ibatis, mybatis - SQL 매핑
JPA - 객체 매핑
스프링 진영에서는 Spring Data JPA를 권장하고 있답니다.
관계형 데이터베이스 외에 다른 저장소로 쉽게 교체하기 위함.
Spring Data JPA, Spring Data Redis, Spring Data MongoDB 등등 하위 프로젝트들은 기본적으로 CRUD 인터페이스가 같기 때문에 저장소 교체되어도 기본적인 기능은 변경할 것이 없음.
JPA 단점: OOP, 관계형 데이터베이스 둘다 이해해야함
JPA 장점:
- CRUD 쿼리 작성 안해도됌
- 클래스로 부모 - 자식 관계 표현 가능
- 1 : N 테이블 관계 표현 가능
- OOP를 사용할 수 있음
Spring Data JPA 적용하기

application.properties에 mysql 연동하는 정보를 작성해두는데, 주석처리해둔 것에 serverTimezone을 추가해주니까.. 동작해요 ㅠㅠㅠㅠㅠㅠ 다행이다 그래도
#spring.datasource.url=jdbc:mysql://localhost:3314/springboot2?useSSL=false
spring.datasource.url=jdbc:mysql://localhost:3314/springboot2?useSSL=false&serverTimezone=Asia/Seoul왜 이런일이 일어났냐면...
도커로 mysql 올렸는데 docker-compose.yam에 TZ부분을 자랑스럽게 넣어서 그렇다..
ports:
- "3314:3306"
environment:
- MYSQL_DATABASE=<database>
- MYSQL_ROOT_PASSWORD=<password>
- TZ=Asia/Seoul 에러2
