今天向伺服器部署一個console java app之後，啟動時發現程式出現異常：

Exception in thread “main” org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 10 in XML document from class path resource [app-config.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element ‘beans’.

然後去看看app-config.xml裡的schema宣告部分，是這樣寫的：

<beans xmlns=”http://www.springframework.org/schema/beans” xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xmlns:context=”http://www.springframework.org/schema/context” xsi:schemaLocation=”http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd” >

很明顯，有關’beans’的宣告都放在http://www.springframework.org/schema/beans/spring-beans-3.0.xsd裡面了。可能是網路原因，訪問不倒導致解析app-config.xml失敗，致使程式丟擲異常。

開啟spring-beans-3.0.1.RELEASE.jar一看，那個xsd檔案就在org.springframework.beans.factory.xml包下面，這下子好辦了，把xsd檔案的引用全改為本地的就行了：

<beans xmlns=”http://www.springframework.org/schema/beans” xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xmlns:context=”http://www.springframework.org/schema/context” xsi:schemaLocation=”http://www.springframework.org/schema/beans classpath:/org/springframework/beans/factory/xml/spring-beans-3.0.xsd http://www.springframework.org/schema/context classpath:/org/springframework/context/config/spring-context-3.0.xsd” >
