.properties 파일이

jdbc.driverClassName=org.postgresql.Driver

이 spring.xml이에

    <bean id="transactionManager" 
      class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

    </bean> 

어떤 도움이 많이 감사합니다, 나는이 때문에 이상한 오류로 진행하는 단지 수없는 오전 파일 이상해.

Answer 1

아직 시도하지 않았다면, pg_hba.conf 파일을 검토하십시오.

/etc/postgresql/9.6/main/pg_hba.conf (Ubuntu 16.04) 
/var/lib/pgsql/9.3/data/pg_hba.conf (Fedora 20); 

find/-name pg_hba.conf를 사용하여 찾을 수 있습니다.

파일 맨 아래에서 METHOD 값을 로컬 테스트에 대한 신뢰로 변경하십시오 (자세한 내용은 postgres docs 참조). 포스트그레스를 다시 시작하여 모든 것이 깨끗하게 시작되고 새 매개 변수가 읽히도록하십시오.

sudo systemctl restart postgresql  # ubuntu 

이렇게하면 문제를 해결할 수 있기를 바랍니다. 그것은 우분투/페도라에서 내 문제를 해결.
