spring mvc启动报错

tomcat启动，报如下错，请问如何处理？

2015-12-31 20:36:28,263 [ERROR] org.springframework.web.servlet.DispatcherServlet - Context initialization failed 
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 8 in XML document from ServletContext resource [/WEB-INF/servlet-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 8; columnNumber: 74; cvc-elt.1: 找不到元素 'beans' 的声明。

servlet-context.xml文件：

<?xml version="1.0" encoding="UTF-8"?>

有可能是引的包，和你声明的4.2.xsd不一致
