spring+hibernate怎么连数据库？
从数据库逆向hibernate生成了hbm.xml和javabean

它自动生成的userDAO，其中的一个方法：
public List findByProperty(String propertyName, Object value) {
log.debug("finding User instance with property: " + propertyName
+ ", value: " + value);
try {
String queryString = "from User as model where model."
+ propertyName + "= ?";
return getHibernateTemplate().find(queryString, value);
} catch (RuntimeException re) {
log.error("find by property name failed", re);
throw re;
}
}

applicationContext配置：
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<constructor-arg>
<ref local="sessionFactory"></ref>
</constructor-arg>
</bean>

<bean id="userDAO" class="com.LostAndFound.dao.userDAO">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<bean id="userService" class="com.LostAndFound.service.UserService">
<property name="userDao">
<ref local="userDAO"></ref>
</property>
</bean>

<bean name="/login" class="com.LostAndFound.myaction.LoginAction">
<property name="userService">
<ref bean="userService"></ref>
</property>
</bean>

运行后：
java.lang.NullPointerException
com.LostAndFound.dao.userDAO.findByProperty(userDAO.java:92)

是不是说findByProperty里 getHibernateTemplate()是空值？是配置错了吗？没取到数据库的数据？

------解决方案--------------------
这里配置可能有问题

<bean id="userDAO" class="com.LostAndFound.dao.userDAO">
 <property name="sessionFactory" ref="sessionFactory"></property>
 </bean>
 
dao里面应该配的是hibernateTemplate吧
