我正在尝试设置我的Spring CAS.XML文件，但我不知道为什么文件没有看到我在文件中设置的值：
有人可以告诉我，我收到了以下错误：
2012-09-10 11:16:00,396 ERROR org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'requestSingleLogoutFilter' defined in ServletContext resource [/WEB-INF/spring/CAS-Local.xml]: Could not resolve placeholder 'cas.server.host'
at org.springframework.beans.factory.config.PlaceholderConfigurerSupport.doProcessProperties(PlaceholderConfigurerSupport.java:209)
如果你看我确实在文件的末尾设置了值...
这是我的CAS-Local.xml文件：

答案 0 :(得分：2)
您对“$ {cas.server.host}”等属性使用占位符，这些属性必须在属性文件中定义并由spring解析。在类路径中创建一个新的属性文件“your.properties”，并将其添加到您的上下文中：
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>your.properties</value>
</property>
</bean>
your.properties：
cas.server.host = HTTP：//本地主机/ ABC
