2、错误原因

[plain] view plain copy

 

1. <bean id="sessionFactory"    
2.        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">    
3.        <property name="dataSource">    
4.                <ref  parent="dataSource"/>  
5.        </property>    
6. </bean>  

     <ref/>中用了parent属性，正确的配置是<ref bean="dataSource"/>

3、解决办法

[plain] view plain copy

 

1. <bean id="sessionFactory"    
2.        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">    
3.        <property name="dataSource">    
4.                <ref  bean="dataSource"/>  
5.        </property>    
6. </bean>
