我这个spring 和mybatis组合出现这个问题怎么解决 找资料了也解决不了

 <bean id="dbcp" 
    class="org.apache.commons.dbcp.BasicDataSource">
    <property name="username" value="root">
    </property>
    <property name="password" value="1234">
    </property>
    <property name="driverClassName"
        value="com.mysql.jdbc.Driver">
    </property>
    <property name="url" 
        value="jdbc:mysql:///cloud_note?useUnicode=true&amp;characterEncoding=utf8">
    </property>
</bean>

<bean id="ssf" 
    class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dbcp">
    </property>
    <property name="mapperLocations" 
        value="classpath:org/tarena/note/sql/*.xml">
    </property>
</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" 
        value="org.tarena.note.dao">
    </property>
    <!-- 自动注入sqlsessionfactory -->
</bean>

<!-- 开启扫描,扫描Controller,Service组件 -->
<context:component-scan 
    base-package="org.tarena.note"/>

<!-- handlermapping,支持@RequestMapping,@ResponseBody,@Exceptionhanlder -->
<mvc:annotation-driven />

严重: Context initialization failed

mybatis的jar包引入了没？把整个工程clean一下再强制maven->update

 <bean id="dbcp" 
    class="org.apache.commons.dbcp.BasicDataSource">

上面是我的applicationContext.xml的内容,<beans xmlns=的内容我没复制过来

应该是配置问题，spring mybatis整合文章 http://58coding.com/article/detail/24659963087429989
