Spring 报错：元素 "context:component-scan" 的前缀 "context" 未绑定的问题解决

Spring 配置文件报错：元素 "context:component-scan" 的前缀 "context" 未绑定,这是我在做项目的时候遇到的，经过项目经理及同事提醒解决了，这里就说下如何解决。

     1.spring配置信息如下

 
 
 
   
  <context:component-scan base-package="com.makelove88.**.dao,com.makelove88.**.service" /> 
   
 
 
 

     2.错误信息如下

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 8 in XML document from URL [file:/E:/InstallSoftware/tomcat/tomcat7u50_8888/webapps/jms/WEB-INF/classes/applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 8; columnNumber: 109; 元素 "context:component-scan" 的前缀 "context" 未绑定。

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener 

【问题分析】

     配置文件中使用了context标签，但未声明。

【解决方案】
    在配置文件中加上context的声明

 
 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 
    ">
