Spring配置错误

我的spring-context文件如下所示.

当我尝试运行我的应用程序时,我收到以下错误:

Caused by: org.springframework.beans.factory.access.BootstrapException: Unable to initialize group definition. Group resource name [classpath*:cfa-spring-context.xml], factory key [cfaBeanFactory]; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Line 16 in XML document from URL [file:/C:/.../cfa-spring-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException: Document root element "beans", must match DOCTYPE root "null".

有人能告诉我我做错了什么吗？

事实证明这是因为我在Spring 1.x中使用Hibernate 3,这意味着DTD是错误的.更新了项目中的Spring JAR文件并修复了问题.
