为什么Sping 找错对象?

 <bean id="exuserDAO" class="com.yourcompany.struts.dao.IbatisExuserDAO">
  <property name="sqlMapClientTemplate">
   <ref bean="sqlMapClientTemplate"/>
  </property>
 </bean>

 <bean id="studentDAO" class="com.yourcompany.struts.ibatis.IbatisStudentDAO">
  <property name="sqlMapClientTemplate">
   <ref bean="sqlMapClientTemplate"/>
  </property>
 </bean>

 

 

后台:org.springframework.beans.factory.BeanCreationException: Error creating bean with name '/studentAction' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type [com.yourcompany.struts.ibatis.IbatisExuserDAO] to required type [com.yourcompany.struts.dao.StudentDAO] for property 'exuserDAO'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [com.yourcompany.struts.ibatis.IbatisExuserDAO] to required type [com.yourcompany.struts.dao.StudentDAO] for property 'exuserDAO': no matching editors or conversion strategy found

/studentAction中调用 exuserDAO 配置没有注入service
初步是没有get set 方法关于 exuserDAO 的
