java - SPRING MVC - IllegalArgumentException : 'sessionFactory' or 'hibernateTemplate' is required

Question

我有这个 Maven 项目及其模块

父级

     |_ persistence-context.xml

     |_ service-context.xml

|_____查看

     |_ spring/app-config.xml

在 persistence-context.xml 中有以下内容:

</bean>
<bean id="bigStockableDao" class="daos.BigStockableDao" >
    <property name="sessionFactory" ref="persistence.sessionFactory" />
</bean>

在该xml中，我用它的sessionFactory制作了我的daos，但是当我启动该项目时，我得到了java.lang.IllegalArgumentException:需要'sessionFactory'或'hibernateTemplate'，因为我的hibernateTemplate为空。我的 daos 扩展自 HibernateDaoSupport，我知道如果你给你的 dao 一个 sessionFactory，它会自动创建一个 hibernateTemplate，并且不知道会发生什么。

我的 daos 有一个 @Repository(例如 @Repository(value="servicioDao"))

以及 @Service 和 setter 中的 @Autowired 服务

我将它们添加到上下文中

   <context:component-scan base-package="controllers" />
   <context:component-scan base-package="servicios" />
   <context:component-scan base-package="daos" />

我只是将其添加到 persistence-context.xml

<!-- Daos beans -->

<bean id="servicioDao" class="daos.ServicioDao" >
    <property name="sessionFactory" ref="persistence.sessionFactory" />
    <property name="hibernateTemplate" ref="hibernateTemplate" />
</bean>
<bean id="stockableDao" class="daos.StockableDao" >
    <property name="sessionFactory" ref="persistence.sessionFactory" />
    <property name="hibernateTemplate" ref="hibernateTemplate" />
</bean>
<bean id="bigStockableDao" class="daos.BigStockableDao" >
    <property name="sessionFactory" ref="persistence.sessionFactory" />
    <property name="hibernateTemplate" ref="hibernateTemplate" />
</bean>

我也遇到同样的错误。

我的一些 daos 代码:

@Repository(value="servicioDao")
@SuppressWarnings("serial")
public class ServicioDao extends GenericHome<Servicio>{
public ServicioDao(){}
@Override
protected Class<Servicio> getDomainClass() {
return Servicio.class;
}
}
public abstract class GenericHome<T> extends HibernateDaoSupport implements     Serializable{
protected Class<T> persistentClass = this.getDomainClass();
protected abstract Class<T> getDomainClass();
}
public class ServicioService {
private ServicioDao servicioDao;
public ServicioService(){}
public ServicioDao getServicioDao() {
return servicioDao;
}
@Autowired
public void setServicioDao(ServicioDao servicioDao) {
this.servicioDao = servicioDao;
}
}

Answer 1

我注意到，当我使用@Service和@Repository时，bean不是由xml创建的，所以当它给我错误“需要'sessionFactory'或'hibernateTemplate'”时，是因为dao已创建但从未填充它sessionFactory，因此为了使用我的 xml 文件，我像普通 bean 一样创建了 Controller
