Non-whitespace characters are not allowed in schema elements

问题：

引用

Caused by: org.xml.sax.SAXParseException; systemId: http://www.springframework.org/schema/aop/spring-aop-4.1.xsd; lineNumber: 1; columnNumber: 134; s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'. Saw 'Your browse does not support frame!'.

原因：
pom.xml配置了对spring 4.1.4.RELEASE的直接依赖，而又间接依赖了spring 3.2.9.RELEASE的，导致解析后的依赖中既有spring 4.1.4的，又有3.2.9的。
解决方法：
通过exclusions排除对3.2.9版本的间接依赖
