SSM整合无法解析$解决方案

在进行Spring+SpringMVC+MyBatis的整合过程中，遇到$符号无法解析

原因是：

<!--配置扫描  -->    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">    <property name="basePackage" value="org.qf.dao"></property>    <property name="sqlSessionFactory" ref="sessionFactory"></property>    </bean>

就在配置的扫描类这有问题，只需将sqlSessionFactory删除掉即可。
