下面是userDAO的配置：
<!-- 用户DAO -->
<bean id="userDAO" class="com.hit.dao.UserDAO">
<property name="sessionFactory">
<ref local="sf" />
</property>
</bean>
"com.hit.dao.UserDAO"这个路径是另一个项目里的，被引用到当前项目中。我已经检查了jar包，applicationContext.xml的路径，但还是解决不掉，希望您能帮帮我，我的分不多了，不好意思。谢谢！
------解决思路----------------------
肯定啊 . 你这个class在别的项目里, 也就是说你启动这个项目时, spring 容器在实例化userDAO bean 的时候,classpath路径下不存在这个.class文件,spring也就无法通过反射加载到这个class,也就无法完成实例化bean了啊
