<property name="dataSource">
<ref bean="dataSource"/>
</property>
<property name="mappingDirectoryLocations">
<list>
<value>${hibernate.mapping.directory}</value>
</list>
</property>
<property name="mappingResources">
<list>
<value>com/you/flex/model/Student.hbm.xml</value>
</list>
</property>3、解决办法
将applicationContext.xml引入的映射文件注释掉
<property name="dataSource">
<ref bean="dataSource"/>
</property>
<property name="mappingDirectoryLocations">
<list>
<value>${hibernate.mapping.directory}</value>
</list>
</property>
<!-- <property name="mappingResources">
<list>
<value>com/you/flex/model/Student.hbm.xml</value>
</list>
