先看我的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/context

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<context:component-scan base-package="cn.edu" />
<!--
<bean id="UserDao" class="cn.edu.spring.dao.MybatisUserDaoImpl"/>
<bean id="UserDao" class="cn.edu.spring.dao.DBUtilsUserDaoImpl"/> -->
</beans>
在网上搜索了一下发现是前一个是publicID，后一个是SystemId，是一一对应的，位置不能颠倒，成对存在
http://www.springframework.org/schema/context // publicID
http://www.springframework.org/schema/context/spring-context.xsd //SystemId
修改之后的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"

一一对应，按顺序来
