Spring中注入service时property报错 notfind dao

Description ResourcePath LocationType

No setter found for property 'teacherDao' in class 'com.service.impl.TeacherService'applicationContext.xml

/TeaPJ/WebRoot/WEB-INF line 42

Spring Beans Problem

<bean id="TeacherService" class="com.service.impl.TeacherService">
<property name="teacherdao" ref="TeacherDao"></property>此处报错





这个问题是出现在dao层中 
在dao层中加入一个setSessionFactory
看它需要setSessionFactoroy这个方法不。


或者这个类，要继承 HibernateDaoSupport这个类


class UserInfoDAO extends HibernateDaoSupport{


}
