求大侠解决，怎么回事！
------解决思路----------------------
sessionFactory没有注入成功。
------解决思路----------------------
在web.xml里加入这个~~ hibernate4 才需要!


<filter>
<filter-name>openSessionInViewFilter</filter-name>
<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
</filter>
