Question

我已经看过几个类似的问题，但没有一个建议的解决方案对我有帮助。

详情，这是一个简单的例子：

文件： MandatTypeBean.xml

<bean id="mandatTypeDAO" class="gestint.data.dao.impl.MandatTypeDAOImpl">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<bean id="ActionMandatType" class="gestint.data.action.MandatTypeAction">
    <property name="mandatTypeDAO" ref="mandatTypeDAO" />
</bean>

文件： HibernateSessionFactory.xml

<bean id="sessionFactory" 
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

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

    <property name="hibernateProperties">
         <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
            <prop key="hibernate.show_sql">true</prop>  
         </props>
    </property>


    <property name="mappingResources">
        <list>
          <value>gestint/data/model/MandatType.hbm.xml</value>
        </list>
    </property>  
</bean>

<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"></property>
</bean>

文件： MandatTypeDAO.java

public class MandatTypeDAOImpl implements MandatTypeDAO {
private SessionFactory sessionFactory;

public SessionFactory getSessionFactory() {
    return sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
     this.sessionFactory = sessionFactory;
}   

public List<MandatType> listMandatType() {      
    sessionFactory.getCurrentSession().isConnected();       

    return null;
}

}

文件： MandatTypeAction.java

public class MandatTypeAction extends ActionSupport{
    private static final long serialVersionUID = 1L;

    private MandatTypeDAO mandatTypeDAO;    
    private List<MandatType> mandatList = new ArrayList<MandatType>();

    public void setMandatTypeDAO(MandatTypeDAO mandatTypeDAO) {
        this.mandatTypeDAO = mandatTypeDAO;
    }

    public List<MandatType> getMandatTypeList() {
        return mandatList;
    }

    public String listMandatType() {            
        mandatList = mandatTypeDAO.listMandatType();
        return SUCCESS;
    }

}

我的错误..

当我尝试访问时 public List<MandatType> listMandatType() 用简单的测试方法：

sessionFactory.getCurrentSession().isConnected();

我收到此错误：

有人可以帮助我吗？

Answer 1

在应用程序上下文xml中添加以下行。

<tx:annotation-driven />

然后用@Transactional注释装饰你的MandateTypeAction类，默认情况下会传播（默认是传播类型为REQUIRED）到被调用的方法。

然后将事务注入MandateTypeAction。

HTH。

Answer 2

为什么要注入SessionFactory？只需直接使用会话：



@Repository
public Mydao {

   @PersistenceContext
   private Session session;

   @Transactional
   public void persist(entity e) {
       session.persist(e);
   }
}

@Repository public Mydao { @PersistenceContext private Session session; @Transactional public void persist(entity e) { session.persist(e); } }

Answer 3

感谢您的支持！它有效，

解决方案是：

我添加了注释驱动文件： HibernateSessionFactory.xml

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

<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"></property>
</bean>

我将注释添加到DAO中文件： MandatTypeDAO.java

    @Transactional(readOnly = true)
public interface MandatTypeDAO {
    @Transactional(readOnly = true)
    List<MandatType> listMandatType();  
}

hibernate4，spring 3：找不到当前线程的Session
