春天的XML錯誤：無法解析佔位符'cas.server.host'

Question

我想安裝我的春天CAS.XML文件，但我不知道爲什麼該文件沒有看到我在文件中設置的值：

有人能告訴我什麼，我收到以下錯誤：

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) 

如果你看我有在文件末尾的值設置...

這裏是我的CAS-本地.xml文件：

Answer 1

您使用像「$ {cas.server.host}」這樣的屬性的佔位符，它必須在屬性文件中定義並在spring中解析。在類路徑中創建一個新的屬性文件 「your.properties」，並添加到您的背景下，這個：

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 
<property name="location"> 
    <value>your.properties</value> 
</property> 
</bean> 

your.properties：

cas.server.host = HTTP：//本地主機/ ABC
