通配符的匹配很全面, 但无法找到元素 context:component-scan

配置完spring后进行单元测试时发生错误

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 14 in XML document from class path resource [conf/application.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 14; columnNumber: 48; cvc-complex-type.2.4.c: 通配符的匹配很全面, 但无法找到元素 'context:component-scan' 的声明。

在xsi:schemaLocation="“中缺少编号3对应的地址，最后加上

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd "

即可
