Question

我正在将工作的hibernate项目转换为Spring hibernate Project。在现有的项目会话中，工厂创建已经通过加载hibernate cfg文件来完成。因为即时春天我通过在java中配置通过Localsessionfactory修改了会话创建。我正在获取一个奇怪的例外如下

ORA-00942: table or view does not exist

但在hiberate cfg查找中同样正常工作。

我正在使用两个transcation manager .Below是我的代码存储库clas

@Repository
public class TestImpl implements
        TestRepository {

    @Autowired
    @Qualifier("fSessionFactory")
    SessionFactory sessionFactory;  

    @Autowired
    @Qualifier("dSessionFactory")
    SessionFactory sessionFactory2;


    @SuppressWarnings("unchecked")
    @Transactional("dTransaction")
    public  Recordse getOrders(String code, int id   ) throws PersistenceException {
            Session session = null;
        try {
            session =sessionFactory.getCurrentSession();
            List<Order> orderList  =  session
                    .createQuery("FROM Orders WHERE CODE = :code  AND NUM_CC = :id " )
                    .setParameter("code", code)
                    .setParameter("id", id)
                    .list();            
                    }
        catch (Exception e) {
            throw new PersistenceException(e);
        }


        return empSickTime ;
    }

    @Transactional("fTransaction")
    @Override
    public SelectedRecords getRecords(String code, String grpId) throws PersistenceException {
        Session session = null;

        try {
            session = sessionFactory2.getCurrentSession();

            List<Records> recList  =  session
                    .createQuery("FROM Records WHERE CODE = :code  AND GRP_CC = :id " )
                    .setParameter("code", code)
                    .setParameter("id", id)
                    .list();            
                    }


        }
        catch (HibernateException e) {
            throw new PersistenceException(e);
        }

        return qualifiedFleet;
    }

    }

        HibernateTransactionManager txManager = new HibernateTransactionManager();
        txManager.setSessionFactory(sessionFactoryFCDS().getObject());

        return txManager;
    }



    Properties hibernateProperties() {
        return new Properties() {
            {
                setProperty("hibernate.hbm2ddl.auto",
                        env.getProperty("hibernate.hbm2ddl.auto"));
                setProperty("hibernate.dialect",
                        env.getProperty("hibernate.dialect"));
                setProperty("hibernate.globally_quoted_identifiers", "true");
            }
        };
    }
}

我错过了什么吗？

Answer 1

@Bean(name="    ")
public LocalSessionFactoryBean sessionFactory() {

看起来您的bean名称不正确？

另一件事是fTransaction您在宣布dSessionFactory

时使用sessionFactory2中的会话工厂

@Autowired
@Qualifier("dSessionFactory")
SessionFactory sessionFactory2;

然后在fTransaction

中使用

@Transactional("fTransaction")
@Override
public SelectedRecords getRecords(String code, String grpId) throws PersistenceException {
    Session session = null;

    try {
        session = sessionFactory2.getCurrentSession();

我猜你指的是错误的数据库连接。

下次我建议为您的属性提供更有意义的名称，例如paymentSessionFactory，geoSessionFactory＆amp;等等，这样你就不会混淆var1 vs session2
