Spring 3.x 和 Hibernate 4 中的事务管理

Question

您好，我在尝试使用 Spring 3.x 和 Hibernate 4 进行事务管理时遇到了障碍。
我在互联网上搜索过，但在 Hibernate 3 中有一些方法可以做到这一点，而在 Hibernate 4 中没有这么多。
我很困惑，我不确定这个设置是否有效。

我正在使用的东西...
春天 3.x
休眠 4

我读过这些
http://static.springsource.org/spring/docs/2.0.x/reference/transaction.html#transaction-declarative
spring, hibernate and declarative transaction implementation: there is no active transaction
还有更多...

跟进
我已经成功地运行了我的课程。我已将proxy-target-class="true" 添加到

<aop:config>

但我不确定这是否在事务中运行。当我使用

时，它会显示 true

TransactionSynchronizationManager.isActualTransactionActive()

但是当我故意在 save 方法中抛出错误时，它不会回滚。

编辑
正如 NimChimpsky 所建议的那样，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

我希望我越来越近了。

log4j 是这么说的。

它确实说 ' Configured SessionFactory: null' 和 'TransactionFactoryInitiator - HHH000399: Using default transaction strategy (direct JDBC transactions)' 但是 c3p0 连接池如何初始化不出错？

我的 Spring 应用程序上下文如下所示。

    <property name="dataSource"><ref bean="dataSource"/></property>
    <property name="configLocation">

TXTestDAO.java
我的 DAO 没有实现 HibernateDAOSupport。我必须实现它吗？

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;
    }

我的测试类
我刚刚使用 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。
我也尽量不使用注释。
我感到很失落 @。@ ！
你能指出我正确的方向吗？

Answer 1

XMLBean 工厂已被弃用，如果可以的话，我建议使用注释和最新最好的 spring 版本（spring 3.2 的测试功能很棒）。它会为你简化一些事情，dao/repository 可以有这个

@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，并在您的配置中添加：

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