applicationContext-security.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 4; columnNumber: 121; cvc-elt.1.a: Cannot find the declaration of element 'b:beans'.
applicationContext-security.xml
F:/apache-tomcat-7.0.68/webapps/yjmanage/WEB-INF/classes/spring_config/applicationContext-mvc.xml 估计是配置文件错误了
