Spring配置文件的问题

提示错误 ：
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.lfw.sh.manager.impl.UserManagerImpl#10b4b2f' defined in class path resource [applicationContext-commom.xml]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: sessionFactory or hibernateTemplate is required
java.lang.IllegalArgumentException: sessionFactory or hibernateTemplate is required

Spring配置文件如下：

我明明已经注入了sessionFactory了呀，怎么还是提示找不到的？
[b]问题补充：[/b]
UserManagerImpl类已经继承了HibernateDaoSupport类
