mybatis的奇怪问题

<!-- springJdbc 访问 正常-->
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource">
<ref bean="dataSource" />
</property>
</bean>
<!-- 加入mybatis报如下错误-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation">
<value>/WEB-INF/SqlMapConfig.xml</value>
</property>
</bean>
