Hibernate + PostgreSQL : 관계가 존재하지 않습니다 - SQL 오류 : 0, SQLState : 42P01

PostgreSQL 및 최대 절전 모드, 특히 제목에서 언급 한 문제로 작업하려고 할 때 문제가 있습니다. 나는 지금 몇 시간 동안 그물을 찾고 있었지만 발견 된 해결책 중 어느 것도 나를 위해 일하지 못했습니다.Hibernate + PostgreSQL : 관계가 존재하지 않습니다 - SQL 오류 : 0, SQLState : 42P01

내가 복사하면 /를 postgre 명령 행에 쿼리를 붙여의 값을 넣어; 그 후에, 그것은 작동합니다.

모든 것이 소문자이므로 그 문제라고 생각하지 않습니다.

MySQL로 전환하면 동일한 코드 (동일한 드라이버, URL, 인증 만 변경)가 작동합니다.

이클립스 데이터 소스 익스플로러에서 DB에 ping을 보내면 성공합니다. 이상한 것은 내가 거기에서 테이블을 볼 수 없다는 것입니다. 공용 스키마를 확장하지만 테이블을 확장하지는 않습니다. 권한 문제 일 수 있습니까?

감사합니다.

JDBC URL은 "jdbc : postgresql : postgres/tommy"입니다. 이는 비정상입니다. documentation은 "jdbc : // hostname/databasename"을 제안합니다. 현대적인 설치에는 거의 확실하게 연결하려는 "postgres"데이터베이스가 있습니다. JDBC 드라이버의 URL 구문 분석이 얼마나 엄격한 지 알 수 없습니다.

데이터베이스 이름과 호스트 이름을 어떻게 예상합니까? 예 : 그런 식으로 데이터베이스에 연결하는 psql의 매개 변수는 무엇입니까?

팁 : postgresql.conf의 일부 설정은 당신이 고려할 수 :

log_connections = on 
log_disconnections = on 
log_line_prefix = '%t %c %q%[email protected]%h:%d '

를 오류가 나는, 이것이 당신의 postgresql.log의 오류와 함께 데이터베이스 이름 등을 기록 할 (잘못된 데이터베이스에 연결하는) 생각하는 경우 파일.

당신이 옳았습니다! conf를 편집하고 postgres 데이터베이스에 연결하고있는 것을 발견했습니다. 데이터 소스 탐색기에서 URL을 얻었습니다. 기본값이었습니다. 그 다음에 '루트'라고 생각하고 데이터베이스 이름 인 tommy를 넣었습니다. 새 URL : jdbc : postgresql : tommy and this 공장. 설명서에 나와있는 양식에 대해 모르겠다. jdbc : // localhost/postgresql/tommy를 시도했지만 작동하지 않았다. 어쨌든, jdbc : postgresql : tommy url과 함께 작동합니다. 정말 고마워요! – user328229

은 데이터베이스가 클라이언트와 동일한 호스트에있는 경우에도 URL 형식을 권장합니다. – araqnid

그 로그는 정말 유용합니다. 필자의 경우, Postgres는 JPA에서 사용하는 << select ... from schema.table >>이라는 형식의 스프링을 좋아하지 않습니다. 대신 Postgres는 << select ... from schema. ""Table ">>을 원합니다. 이제 JPA가 그 형식을 사용하는 방법을 알아 내야합니다. – riverhorse

나는 스키마를 지정하여 동일하거나 유사한 문제를 방금 해결했습니다. 이 질문의 주제 제목 건너 일이 다른 사람을 위해 유용 할 수 있습니다 -

@Entity 
@Table(name = "mytable", schema="myschema") 
public class MyTable implements Serializable { 
    ...

또 다른 대답은 스키마 권한을 확인 할 수 있습니다. 나는 정확한 오류 메시지와 관련된 증상이 있었다.

<SQL Error: 0, SQLState: 42P01> 
<ERROR: relation "tablename" does not exist>

해결 방법은 로그인 할 때 사용한 사용자의 해당 스키마에 대한 사용 권한을 활성화하는 것이 었습니다.

또한 좋은 진단 도구는 프로그램에서 사용하는 것과 동일한 사용자로 postgres 명령 줄 콘솔에 로그인하고 같은 방식으로 테이블과 스키마에 액세스하는 것입니다.
