Answer 1

请把你的spring xml发出来看看
大概的在配置里
<bean id="commonDao" class="xxxxxxxxxxx.xxx.xx">
<property ....../>
......
</bean>
id为commonDao对应的类...（不知道你的配置只能用xxxxxx来替代了）需要注入ref="sessionFactory" 这个bean但找不到....

这里面可能的解决方法是：
1在这个类的配置里添加一个property属性
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
应该就不会报错了。
2看看该commonDao对应的类是否继承了hibernateDaoSupport

Answer 2

在applicationContext.xml文件下
<bean id="commonDao".. 配置错误.
缺少<property name="sessionFactory".. 或者 sessionFactory配置错误
