本文分析了Spring框架中出现的依赖注入错误案例，探讨了配置文件与Java代码间不匹配导致的问题，具体表现为期望类型与实际类型不符。通过对比正确的依赖注入方式，指出了修正方法。

配置文件不变：

<bean id="commoCategoryServComponent" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">
        <property name="serviceUrl" value="${ecos_commodity_remote.url}/ICommoCategoryServComponent"/>
        <property name="serviceInterface" value="org.lazicats.ecos.commodity.service.component.ICommoCategoryServComponent"/>
    </bean>
    
     <bean id="categoryServComponent" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">
        <property name="serviceUrl" value="${ecos_commodity_remote.url}/IOperatingCategoryServComponent"/>
        <property name="serviceInterface" value="org.lazicats.ecos.commodity.service.component.IOperatingCategoryServComponent"/>
    </bean>

引用的java变动：

   @Resource
   private ICommoCategoryServComponent categoryServComponent;
   but was actually of type [$Proxy7]
   org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productStockController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productStockViewComponentImpl': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'categoryServComponent' must be of type [org.lazicats.ecos.commodity.service.component.ICommoCategoryServComponent], but was actually of type [$Proxy7]
   org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:894)
   org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:778)
   下面就OK
   @Resource
   private ICommoCategoryServComponent commoCategoryServComponent;
