從Hibernate和Spring連接到多個數據庫

我需要在我的spring hibernate應用程序中連接到兩個數據庫。從Hibernate和Spring連接到多個數據庫

的配置如下：

我試圖讓在代碼中兩個不同的會話工廠，但它不工作我得到這個錯誤：

25731 [23 Jun 2013 15:41:36 512] [qtp259913092-20] [ERROR] errorId=org.hibernate.HibernateException: No Session found for current thread

我試圖定義我的課程如下：

@Repository 
public class UsersBMDao extends HibernateTemplate{ 
    private static Logger LOG = LoggerFactory.getLogger(UsersBMDao.class); 

    @Autowired 
    SessionFactory sessionFactory; 

    @Autowired 
    public UsersBMDao(@Qualifier("sessionFactory2") SessionFactory sessionFactory) { 
     super(sessionFactory); 
    } 

    public List<UsersBM> getAllUsers(){ 
     Criteria crit = sessionFactory.getCurrentSession().createCriteria(UsersBM.class); 
     return crit.list(); 
    } 
}

但它不工作 - 任何方向將有所幫助！

感謝名單

----------------我試圖@Transactional添加到類（的建議），並得到這個異常：

最後我已經解決了它這樣的：

@Repository 
public class TstDao{ 

    private static Logger LOG = LoggerFactory.getLogger(TstDao.class); 

    @Autowired 
    @Qualifier(value="transactionManager2") 
    private PlatformTransactionManager tm; 
    private TransactionTemplate transactionTemplate; 

    @PostConstruct 
    public void init(){ 
     transactionTemplate = new TransactionTemplate(tm); 
     LOG.debug("tm="+tm); 
    } 

    @Autowired 
    @Qualifier(value="sessionFactory2") 
    SessionFactory sessionFactory; 

    public List<Obj_Test> getAllUsers(){ 
     return transactionTemplate.execute(new TransactionCallback<List<Obj_Test>>() { 

      @Override 
      public List<Obj_Test> doInTransaction(TransactionStatus status) { 

       Criteria crit = sessionFactory.getCurrentSession().createCriteria(Obj_Test); 
       return crit.list(); 

      } 

     }); 
    } 
}

在我擁有了一切複製以及配置和它的工作原理類似。
