使用idea开发时，在SSM框架下进行mapper的自动扫包sqlSessionFactoryBeanName标红，和遇到的错误

配置mapper自动扫描器的代码

    <property name="configLocation" value="classpath:sqlMapConfig.xml"/>

    <property name="mapperLocations" value="classpath:cn/itcast/mapper/*.xml"/>
</bean>

<!--mapper自动扫描器-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    <property name="basePackage" value="cn.itcast.mapper"/>

</bean>

遇到的问题：
sqlSessionFactoryBeanName直标红，并且运行时出现错误：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.mybatis.spring.mapper.MapperScannerConfigurer#0’ defined in class path resource [beans.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property ‘sqlSessionFactoryBeanName’ of bean class [org.mybatis.spring.mapper.MapperScannerConfigurer]: Bean property ‘sqlSessionFactoryBeanName’ is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

经过长时间的查找，发现是pom.xml中的依赖版本过低，所以去看一下源码中是否有sqlSessionFactoryBeanName这个方法，
依赖的代码：
