Struts Hibernate spring 3层框架做项目 我把biz注入到Action中，运行时报空指针异常，检查后发现scenicgoodsbiz是空的请教各位到底是什么原因造成的 ，很急的

配置文件

<bean id="Scenicgoodsinfo" class="com.enfang.daoImpl.ScenicgoodsImpl" >
    <property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<bean id="ScenicgoodsManager" class="com.enfang.bizImpl.ScenicgoodsManagerImpl">
    <property name="scenicgoodsdao" ref="Scenicgoodsinfo"></property>
</bean>

<bean name="/scenicgoods" class="com.enfang.struts.action.ScenicgoodsAction">
    <property name="scenicgoodsbiz" ref="ScenicgoodsManager"></property>
</bean>

Action 注入

<bean id="Scenicgoodsinfo" class="com.enfang.daoImpl.ScenicgoodsImpl" >
    <property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<bean id="ScenicgoodsManager" class="com.enfang.bizImpl.ScenicgoodsManagerImpl">
    <property name="scenicgoodsdao" ref="Scenicgoodsinfo"></property>
</bean>

<bean name="/scenicgoods" class="com.enfang.struts.action.ScenicgoodsAction">
    <property name="scenicgoodsbiz" ref="ScenicgoodsManager"></property>
</bean>

错误找出来了 我的包出问题 要把cglib-2.1.3.jar 删除 就好了
还有救是Struts-config.xml 里面的配置 写错了个字母
谢谢大家

应该是spring没能注入，一般情况下，action中需要有set方法用来注入这个biz

应该不可能的，除非你就是没注意好，没set注入成功

把配置文件粘出来嘛

自己仔细看看有没写错字母啊

ScenicgoodsAction这个类里有不是有这个属性scenicgoodsbiz，自己去看清楚些

如果写的都对的，会不会是你的struts中的action类没有被spring管理？
一种比较常用的struts与spring集成：
struts配置里面action的type=org.springframework.web.struts.DelegatingActionProxy
还有web.xml中有没启动spring

我怀疑你是没整合成功struts和spring吧
