Spring,Hibernate Lazy Loading,sessionFactory和OpenSessionInViewFilter
作者:互联网
我正在使用Hibernate的延迟加载,并且即使在我在web.xml中定义了一个过滤器以使用OpenSessionInViewFilter之后,我也得到了sessionFactory缺少的异常

我的servlet-context.xml具有以下会话和事务管理器定义:
<beans:bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<beans:property name="dataSource" ref="dataSource"/>
<beans:property name="hibernateProperties">
<beans:props>
<beans:prop key="hibernate.dialect">${connection.dialect}</beans:prop>
<beans:prop key="hibernate.show_sql">true</beans:prop>
</beans:props>
</beans:property>
<beans:property name="annotatedClasses">
<beans:list>
<beans:value>example.EntityA</beans:value>
<beans:value>example.EntityB</beans:value>
</beans:list>
</beans:property>
</beans:bean>
<beans:bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<beans:property name="sessionFactory" ref="sessionFactory"/>
</beans:bean>
<tx:annotation-driven transaction-manager="transactionManager" />
我仍然得到以下异常:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'sessionFactory' is defined
我已经尝试定义sessionFactoryBeanName属性但结果不会更改.我究竟做错了什么?
解决方法:
您需要在根Web应用程序上下文中声明sessionFactory(即.WEB-INF/spring/root-context.xml),以使其可用于OpenSessionInViewFilter.
