Exception in thread "main" org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:

最近在spring中遇到的问题,如下:

Exception in thread "main" org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 11 in XML document from class path resource [bean.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 11; 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。

错误的bean.xml:

 1 <?xml version="1.0" encoding="UTF-8"?>
 2   <beans xmlns="http://www.springframework.org/schema/beans"
 3          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4          xmlns:context="http://www.springframework.org/schema/context"
 5          xsi:schemaLocation="
 6          http://www.springframework.org/schema/beans
 7          http://www.springframework.org/schema/beans/spring-beans.xsd
 8          http://www.springframework.org/schema/context/spring-context.xsd
 9          http://www.springframework.org/schema/context">
10   </beans>

xsi:schemaLocation 是相当于key-Value，中间用空格隔开。后面是xsd文件的地址.

改正后:

 1 <?xml version="1.0" encoding="UTF-8"?>
 2   <beans xmlns="http://www.springframework.org/schema/beans"
 3          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4          xmlns:context="http://www.springframework.org/schema/context"
