spring social quick start sample을 기존 프로젝트에 적용하려고합니다. 데이터베이스 부분을 제외한 모든 것이 잘 작동하는 것 같습니다. 나는 응용 프로그램을 빌드하려고 할 때마다스프링이 데이터 소스 빈을 만들 수 없습니다.
, 나는이 오류 얻을 : 당신이 볼 수 있듯이

이 문제는 데이터베이스를 만드는 동안 발생하는 것 같습니다,하지만 그 이유를 모르겠어요.
"USERCONNECTION"테이블이 이미 있습니다. SQL 문 ... –
어떤 아이디어가 기존 테이블을 제거하는 방법? – fxm
네, 여러 가지 옵션이 있지만 전체 프로젝트를 보지 않고서는 정확하지 않을 수 있습니다. 먼저 모든 실행 전에 전체 데이터베이스를 삭제할 수 있습니다. 이렇게하면 코드가 문제없이 테이블을 다시 작성할 수 있습니다. 둘째, 테이블 이름이 무엇인지 알아 내고 스크립트가 실행될 때마다 스크립트를 실행하면 다시 실행간에 데이터가 삭제됩니다. 셋째, 이렇게하면 데이터베이스 스크립트가 자동으로 실행되지 않습니다. DB 작업을 수동으로 실행하여 시스템을 실행하기 전에 DB를 사양에 맞게 만듭니다. –
