플라이 웨이 jdbc 마이 그 레이션 연결 문제

플라이 웨이 JDBC 마이 그 레이션에 문제가 있습니다. 모든 문장을 실행 한 후 conn.close(); 메소드로 DB 연결을 닫으려고하는데 org.postgresql.util.PSQLException: This connection has been closed. 예외가 발생합니다. 데이터베이스를 검사 할 때 마이그레이션 내에서 수행 한 모든 변경이 완료되었지만 schema_version 테이블은 업데이트되지 않습니다. 마이그레이션에 대한 항목이 추가되지 않았습니다.
자세한 내용은 여기를 참조하십시오 :
flyway.properties에서 classpath:com/packageone/somepackege/database/migration을 flyway.locations 섹션에 추가했습니다. public class V1_1_1__SomeImportantMigration implements JdbcMigration하고 그런 migrate 방법에 충전 : 그럼 마이그레이션을 수행하는 클래스를 작성한 migrate 방법으로 수행된다
플라이 웨이 jdbc 마이 그 레이션 연결 문제

@Override 
     public void migrate(Connection conn) throws Exception { 
      beforeActions(conn); 
      veryImportantMigration(conn, getData(conn)); 
      afterActions(conn); 
      conn.close(); 
     }

일은인가하지만, 연결을 종료하는 것은 예외로 연결된다.
위에서 설명한 정보로 인해 다음과 같은 질문이 있습니다. 왜이 연결이 닫히기 전에 닫혀 있습니까? 뭘로?

당신은 그들이 부분적으로 완료되었다고 말하고 있습니다. 누락 된 예외가 있습니까? 로그를 제공 할 수 있습니까? – Korgen

당신은 그 연결을 닫아서는 안되며, 그것은 flyway 소유입니다. –

@Korgen, 로그를 공유 할 수 있습니다. 부분적으로 Cocerning - 그건 내 실수 였어 ... –

당신은 철새 이동 경로가 제공 한 연결에 close()를 호출하지 않아야합니다. 이동 경로는 다른 하우스 키핑 작업 (버전 테이블 업데이트 포함)에이 연결 자체를 사용하고 닫으면 이동 경로가 제대로 작동하지 않습니다.
