哪位帮看看我的SPRING配置出了什么问题

[waiwai2902]

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'login' defined in

file [E:\Java\tomcat\tomcat6\webapps\copycode\WEB-INF\classes\applicationContext.xml]: Cannot resolve

reference to bean 'LoginService' while setting bean property 'LoginService'; nested exception is

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'LoginService' defined

in file [E:\Java\tomcat\tomcat6\webapps\copycode\WEB-INF\classes\applicationContext.xml]: Instantiation of

</beans>




不知道怎么搞的

[waiwai2902]

原来错误就一个,在DAO里注入Sessionfactory,就OK了

[临远]

无法实例化一个接口
com.copycode.service.LoginService

这里需要使用实体类。

[小明和小红]

没有注入实体类吧?

[wang_zhilin]

<!-- action -->
<bean id="login" class="com.copycode.action.LoginAction">
<property name="LoginService" ref="LoginService"></property>
</bean>


改Id为name

[aSysBang]

<bean id="login" class="com.copycode.action.LoginAction">
LoginAction这个是接口吧
class要指定到LoginAction这个接口的实现类
