2、错误原因

<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>

导入Hibernate包时，MyEclipse会自动生成一个HibernateSessionFactory类，而这个会从hibernate.cfg.xml读取配置属性；又在applicationContext.xml中引入Student.hbm.xml，所以导致重复读取hibernate映射文件

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>
		</property> -->
