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
<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"
xsi:schemalocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<!-- 自动扫描dao和service包(自动注入) -->
<<span style="color: #ff00ff;">context:</span>component-scan base-package="com.makelove88.**.dao,com.makelove88.**.service" />
<import resource="classpath*:*/applicationcontext-*.xml" />
</beans>
2.错误信息如下

【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
