Spring, JPA, Hibernate, Postgresql을 사용하고 있습니다. 데이터베이스에 파일을 업로드/삽입 할 수 있습니다. 하지만 파일에 액세스하려고하면 오류가 발생합니다.org.postgresql.util.PSQLException : 대형 객체는 자동 커밋 모드에서 사용할 수 없습니다.

<c:forEach items="${purchaseOrder.purchaseOrderQuotes}" var="document">

I는 PurchaseOrder에 검색 방법 : 여기

@Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW) 
    public PurchaseOrder findById(Integer id) 
    { 
     log.debug((new StringBuilder("getting PurchaseOrder instance with id: ")).append(id).toString()); 
     try 
     { 
      PurchaseOrder instance = entityManager.find(PurchaseOrder.class, id); 
      //   if(instance.getProjectFundingYears() != null) 
      //    log.debug("get successful"); 
      //   log.debug("get successful"); 
      return instance; 
     } 
     catch(RuntimeException re) 
     { 
      log.error("get failed", re); 
      throw re; 
     } 
    }

두 엔티티의 관계 :

01,235,

나는 명확하지 않다. 죄송합니다. 여기 BLOB 파일에 직접 액세스하지 않고 부모 개체를 가져옵니다.

파일을 업로드하고 purchaseOrder를 아무 문제없이 검색 할 수있었습니다. 이 부분 코드를 JSP 파일에 추가 할 때만 오류가보고됩니다. 하지만 FetchType.LAZY를 설정 했으므로 BLOB 필드에 액세스해서는 안됩니다. 혼란스러워. 당신이 @Transactional를 통해 봄 거래를 정의한 이후

<c:forEach items="${purchaseOrder.purchaseOrderQuotes}" var="document"> 
         <tr> 
          <td> 
           ${document.name} 
          </td> 
          <td> 
           ${document.description} 
          </td> 
          <td align="left"> 
           ${document.filename} 
          </td> 
          <td> 
           ${document.created} 
          </td> 

          </td> 
         </tr> 
     </c:forEach>

큰 개체를 실제로 사용해야합니까? 어떤 종류의 바이너리 데이터를 저장하고 있습니까? 1GB 이상을 저장하거나 BLOB의 일부만 액세스해야하는 경우가 아니라면, 'bytea'가 훨씬 더 나은 선택입니다. –

사람들이 크기가 10MB 미만인 파일 만 업로드 할 수있게하면됩니다. 나는 무슨 일이 일어 났는지보기 위해 bytea를 시도 할 것이다. – Alex

, 당신은 자동 커밋 트랜잭션 내에서 실행 기본적으로 있습니다. this other thread에 따라 autocommit = false에서 실행되는 두 번째 세션 팩토리를 만들어 파일을 검색해야합니다.

또한 검색을위한 DAO에는 @Qualifier이라는 주석이 달려 있어야 사용할 세션 팩토리를 알 수 있습니다. 예 :

@Autowired 
public MyDAOImpl(@Qualifier("someSessionFactory") SessionFactory sessionFactory) { 
    setSessionFactory(sessionFactory); 
}
