Spring Boot JPA 설정 오류 해결: Hibernate Dialect 문제
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment] due to: Unable to determine Dialect without JDBC metadata (please set 'jakarta.persistence.jdbc.url' for common cases or 'hibernate.dialect' when a custom Dialect implementation must be provided)
❗EntityManagerFactory를 생성하는 과정에서 Hibernate가 데이터베이스 Dialect를 결정할 수 없다
✔️ Dialect 설정이 누락되었거나 잘못된 경우 발생
