이송 경로 데이터 가져 오기는 H2 용이 아닌 MySQL에서만 작동합니다.

Question

약간의 스프링 부팅 응용 프로그램이 있습니다. 기본 프로필과 mysql 프로필. 기본적으로 inMemory 모드에서 H2 데이터베이스를 시작하려고합니다. 두 데이터베이스 모두 두 개의 flyway 파일로 초기화합니다 (데이터베이스 설정 및 일부 테스트 데이터). mysql 모드에서 응용 프로그램을 실행하면 정상적으로 작동합니다. 기본 모드에서 응용 프로그램을 실행하면 testdata는없고 emtpy 테이블 만 얻습니다. 유일한 차이점은 콘솔에서 4 개의 최대 절전 모드 외래 키 오류가 발생한다는 것입니다.

Answer 1

솔루션 :

application.properties

spring.jpa.hibernate.ddl-auto=none

가에 생성 놓기 전에

. flyway가 데이터베이스를 설정하고, 최대 절전 모드에서 데이터베이스를 삭제 한 다음 다시 만듭니다. mysql 데이터베이스에서 mysql 모드로 작동하는 이유는 무엇입니까?

Answer 2

는 외래 키와 대소 문자 변환의 이름에 문제가 없습니다. 처럼 FKS 이름을보십시오 :

CONSTRAINT FK_ADDRESS_COMPANY FOREIGN KEY (COMPANY_ID) REFERENCES COMPANY(ID)
