spring中的问题jar包版本冲突和class路径问题

1.在运行spring程序，bean中的class路径不对时，报如下错误：

Exception in thread "main" org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 5 in XML document from class path resource [applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'beans'.

查找了下，又搜索了下网上的方法，发现导入的jar包中，有版本不匹配的，把对应的spring的jar包换成同一个版本的即可
