Answer 1

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref local="sessionFactory"/>
</property>

Answer 2

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref local="dataSource"/>
</property>

Answer 3

bean 初始化 失败 ,回答如上.

Answer 4

正解。楼主配置之时估计是大意了。dataSource的引用当然是要指向dataSource的bean啦，而楼主确是指向了sessionFactory

Answer 5

楼上+1 sessionfactory只向datasource

Answer 6

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref local="sessionFactory"/>
</property>
应该改为<ref local="dataSource"/>

Answer 7

dataSource与sessionFactory怎么可能，配置错了
