【BUG记录】Content is not allowed in prolog错误

今天出现了Content is not allowed in prolog.错误，本以为是tomcat的lib错误。重新下了个新的tomcat，依旧如此。后来才发现是XML文件写的格式错误。

Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 1 in XML document from URL [file:/E:/wjxServer/apache-tomcat-6.0.37/lib/] is invalid; nested exception is org.xml.sax.SAXParseException: Content is not allowed in prolog.

在web.xml中  classpath*: 后面多了个空格。

  contextConfigLocation
    classpath*: mvc/emvc.xml
  

改为：

  contextConfigLocation
    classpath*:mvc/emvc.xml
  

问题解决。
