通配符的匹配很全面, 但無法找到元素 'context:component-scan' 的聲明

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

最近在spring中遇到的問題,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, 但無法找到元素 'context:component-scan' 的聲明。

錯誤的bean.xml:

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

 

xsi:schemaLocation 是相當於key-Value，中間用空格隔開。后面是xsd文件的地址.

改正后:

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