springboot 은 다 중 데이터 원본 을 설정 하고 Druid 와 my batis 를 통합 합 니 다.

my sql,Oacle 등 다양한 데이터 원본 일 수 있 습 니 다.
프로젝트 구조

메모:@Primary 데이터 원본 이 제어 하 는 mapper 파일 에 주석@Mapper 만 있 습 니 다.그렇지 않 으 면 my batis 에서 스 캔 을 전환 할 수 없습니다.즉,본문 에 있 는 mapper/opener 폴 더 에 mapper 주 해 를 추가 합 니 다.
1、pom
드라이브 외 에 druid 와 my batis 등 pom 을 추가 하여 my batis 를 통합 하여 자체 검색 합 니 다.

코드 호출
간단 합 니 다.어떤 데이터 소스 서 비 스 를 사용 하여 어떤 mapper 를 주입 하면 됩 니 다.

이상 은 개인 적 인 경험 이 므 로 여러분 에 게 참고 가 되 기 를 바 랍 니 다.여러분 들 도 저 희 를 많이 응원 해 주시 기 바 랍 니 다.
