spring 注入的时候抛这样的异常【求解】

其中spring xml文件中的代码：
<!-- 文件操作注入 -->
<!-- 注入services层 -->
<bean id="fileservices" class="wqcom.zh.nms.web.services.Impl.IfilerservicesImpl">
<property name="filedao" ref="fileDao" />
</bean>
<!-- 注入action层 -->
<bean id="fileAction" class="wqcom.zh.nms.web.action.FileAction">
<property name="ifileservices" ref="fileservices" />
<property name="isofttypeservices" ref="softteype" />//主要加了这句话抛的异常
</bean>
<!-- 注入services层 -->
<bean id="softteype" class="wqcom.zh.nms.web.services.Impl.IsofttypeservicesImpl">
<property name="itypedao" ref="typedao" />
</bean>
<!-- 注入action层 -->
<bean id="softAction" class="wqcom.zh.nms.web.action.SofttypeAction">
<property name="isofttypeservices" ref="softteype" />
</bean>

解决方案 »

  1.   

    你是否在FileAction中定义的isofttypeservices是这样定义的：
    IsofttypeservicesImpl isofttypeservices;
    如果是这样的话，你应该改成:
    Isofttypeservices isofttypeservices;
      

  2.   

    fileAction isofttypeservices类的包引用有错吗? 
      

  3.   

    isofttypeservices 是这个方法名吗?
    wqcom.zh.nms.web.services.Isofttypeservices,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised] to required type [wqcom.zh.nms.web.services.Impl.IsofttypeservicesImpl] for property 'isofttypeservices': no matching editors or conversion strategy found
    注意看这句
