缺少 Hibernate sessionFactory 或 Hibernate 模板

Question

每次更改xml 文件时都会出现此错误。这是我得到的：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'managerExpedBitacora' defined in class path resource [config/spring/manager.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' is required

这是我的manager.xml，仅供参考：

<bean id="managerExpedBitacora" class="es.myCompany.lq.manager.impl.ManagerExpedBitacoraImpl">
             <property name="daoExpedBitacora" ref="daoExpedBitacora"/>  
</bean>

...
<bean id="managerExpedienteLS" class="es.myCompany.lq.manager.impl.ManagerExpedienteLSImpl">
     ....
     <property name="managerExpedBitacora" ref="managerExpedBitacora" />
     ....
</bean>

这是我的daos.xml，只有几行：

<bean id="daoExpedBitacora" class="es.myCompany.lq.dao.impl.DaoExpedBitacoraHbmImpl">
     <property name="sessionFactory" ref="sessionFactory"/>
</bean>

如您所见，我已经注入了 sessionFactory。

还有，applicationContext.xml，邮件部分：

<import resource="classpath:config/spring/properties.xml"/> 
<import resource="classpath:config/spring/utils.xml"/>
<import resource="classpath:config/spring/bbdd.xml"/>
<import resource="classpath:config/spring/daos.xml"/>
<import resource="classpath:config/spring/manager.xml"/>
<import resource="classpath:config/spring/actions.xml"/>

还有，我的一部分DaoExpedBitacoraHbmImpl.java：

public class DaoExpedBitacoraHbmImpl extends HibernateDaoSupport implements
    DaoExpedBitacora {
...(methods)
}

而且，HibernateDaoSupport.java，只是其中的一部分。

public class HibernateDaoSupport extends org.springframework.orm.hibernate4.support.HibernateDaoSupport{
....
}

那么，这里有什么问题？

我的项目负责人看了代码，说我的ManagerExpedBitacoraImpl.java，作为服务的实现，不能扩展HibernateDaoSupport.java。这是我没有发布的部分。所以之前是这样的：

public class ManagerExpedBitacoraImpl extends HibernateDaoSupport implements ManagerExpedBitacora {

    DaoExpedBitacora daoExpedBitacora;

    public DaoExpedBitacora getDaoExpedBitacora() {
    return daoExpedBitacora;
    }

    public void setDaoExpedBitacora(DaoExpedBitacora daoExpedBitacora) {
    this.daoExpedBitacora = daoExpedBitacora;
    }
....

应该是这样的：

public class ManagerExpedBitacoraImpl implements
    ManagerExpedBitacora {

    DaoExpedBitacora daoExpedBitacora;

    public DaoExpedBitacora getDaoExpedBitacora() {
    return daoExpedBitacora;
    }

    public void setDaoExpedBitacora(DaoExpedBitacora daoExpedBitacora) {
    this.daoExpedBitacora = daoExpedBitacora;
    }
....

而在其他管理器实现类中，我看不到这部分。一定是一些误点击。所以我删除了这部分，一切都很好。希望我可以帮助其他人。
