问题解决

spring配置<context:component-scan base-package="包名" />，报如下错误：

The prefix "context" for element "context:component-scan" is not bound.

是因为该配置文件的<bean></bean>标签的属性中少了属性信息，增加相应属性即可，如下：

xmlns:context="http://www.springframework.org/schema/context"

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
