Spring 3.x和Hibernate 4中的事务管理

Question

您好我已经面对一堵墙，而我试图使用Spring 3.x和hibernate4.做交易管理
我搜索在互联网上，但有办法在hibernate3要做到这一点，没有那么多的hibernate4.
I”我很困惑，我不确定此设置是否有效。

我正在使用的东西…
Spring 3.x
Hibernate 4

我已经阅读了这些
http://static.springsource.org/spring/docs/2.0.x/reference/transaction.html#transaction-
declarative spring，hibernate和声明式事务的实现：没有活动的事务
，还有更多事务 …

后续
我已经成功地运行了我的课程。我已添加proxy-target-class="true"到

<aop:config>

但是我不确定这是否正在事务中运行。它说true我使用时

TransactionSynchronizationManager.isActualTransactionActive()

但是当我有意在save方法中引发错误时，它不会回滚。

编辑
如NimChimpsky所建议，我尝试通过Spring MVC（dispatcher servlet）调用相同的方法，它说

    Cannot convert value of type 
[$Proxy19 implementing kr.co.sgis.services.web.cooingbee.Crudable,org.springframework.aop.SpringProxy,
org.springframework.aop.framework.Advised] to required type
[test.TXTestDAO] for property 'dao': 
no matching editors or conversion strategy found

我希望我越来越近。

log4j这样说。

它会说' Configured SessionFactory: null'，'TransactionFactoryInitiator - HHH000399: Using default transaction strategy (direct JDBC transactions)'但是c3p0连接池如何初始化而不会出现错误？

我的spring应用程序上下文看起来像这样。

hibernate.cfg.xml

TXTestDAO.java 我的DAO没有实现HibernateDAOSupport。我必须执行它吗？

public int save(CooingbeeFetchable bean) {
        // TODO Auto-generated method stub
        try{

            sessionFactory.getCurrentSession().getTransaction().begin();
            //Using sessionFactory is low level
            sessionFactory.getCurrentSession().save(bean);

            sessionFactory.getCurrentSession().getTransaction().commit();
            System.out.println("committed");

        }catch(Exception e){
            e.printStackTrace();
        }
        return 0;
    }

我的测试课程只是使用FileSystemResource进行测试。

public class Tester {       
public static void main(String[] args){

            FileSystemResource fSysSrc = new FileSystemResource("C:\\SGI_Project\\eclipseWorkspace\\SPSWeb\\WebContent\\WEB-INF\\SpringDispatcher-servlet.xml");
            BeanFactory xmlBeanFactory = new XmlBeanFactory(fSysSrc);
            TXTestService txDAO= (TXTestService) xmlBeanFactory.getBean("testTxService");

            TXTestBean bean = new TXTestBean();

            bean.setName("bodybody");
            txDAO.save(bean);

        }
    }






public class TXTestService implements Crudable{

    private TXTestDAO dao;

    public void setDao(TXTestDAO nDAO){
        dao = nDAO;
    }
public int save(CooingbeeFetchable bean) {
        // TODO Auto-generated method stub
        return dao.save(bean);
    }
}

到目前为止，我没有找到当前线程异常的会话。 我也试图不使用注释。 我感到很失落 @。@ ！
你能指出我正确的方向吗？

Answer 1

不推荐使用XMLBean工厂，如果可以的话，我建议您使用注释和最新最好的Spring版本（spring 3.2的测试功能很棒）。它将为您简化一些事情，Dao/存储库可能有此功能

@Resource(name = "sessionFactory")
private SessionFactory sessionFactory;

@Transactional(propagation = Propagation.REQUIRED)
 public T save(final T o) {
        return (T) sessionFactory.getCurrentSession().save(o);
    }

然后可以将其本身注入，并在yr config中添加以下内容：

 <tx:annotation-driven transaction-manager="transactionManager"/>
