在学习Dubbo中遇到了这个问题
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 12 in XML document from URL [file:/F:/workspace/spring/target/classes/applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 12; columnNumber: 55; 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。
这个问题其实特别简单，就是在xml的配置文件中，只引入了context命名空间，但并没有引入schemaLocation
如下标红所示，引入即可
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://dubbo.apache.org/schema/dubbo" xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
