Caused by: org.xml.sax.SAXParseException; systemId: http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd; lineNumber: 24; columnNumber: 20; cos-all-limited.1.2: An ''all'' model group must appear in a particle with '{'min occurs'}'='{'max occurs'}'=1, and that particle must be part of a pair which constitutes the '{'content type'}' of a complex type definition.

自己解决,maven出现问题首先检查有没有jar包版本冲突~,换个jar包就OK了
