具有两个Spring配置上下文XML文件的bean引用

当在其他Spring上下文XML文件中引用bean时,我总是能让它正常工作,但这次不行:

springapp-servlet.xml:

 <!-- Spring Controllers -->
<b:bean id="loginSpringController" class="com.foo.bar.controllers.spring.LoginController"/>
<b:alias name="loginSpringController" alias="loginSprController"/>   

应用程序上下文.xml

<!-- Custom AuthenticationProcessingFilter with Callbacks -->
<authentication-manager alias="authenticationManagerAlias"/>
<b:bean id="authenticationProcessingFilter" name="authenticationProcessingFilter" class="com.foo.bar.support.event.CustomAuthenticationProcessingFilter"> 
<b:property name="authenticationManager" ref="authenticationManagerAlias"/>
<b:property name="authenticationFailureUrl" value="/login.do?1=1"/>
<b:property name="filterProcessesUrl" value="/j_spring_security_check"/>
<b:property name="callback" ref="successfulAuthenticationCallbackImpl"/>
<b:property name="defaultTargetUrl" value="/index.html"/>
<!-- Reference to the sprint controller -->
<b:property name="loginSpringController"><b:ref bean="loginSprController"/></b:property>
<custom-filter position="AUTHENTICATION_PROCESSING_FILTER" />          

但是我仍然得到这个错误(即使没有别名):

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'loginSprController' is defined
