spring整合hibernate出现异常：org.apache.commons.dbcp.BasicDataSource

spring-4.2.5 hibernate-5.1.0
spring整合hibernate时想使用spring提供的sessionfactory遇到下面的异常：

警告: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.apache.commons.dbcp.BasicDataSource] for bean with name 'myDataSource' defined in ServletContext resource [/WEB-INF/applicationContext.xml]; nested exception is java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource

在网上搜了一下，都是说缺少了commons-dbcp和commons-pool这两个包，我都加到lib目录下之后问题依然存在，求解？

以下是spring的配置，copy官方文档的

<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost/myssh"/>
    <property name="username" value="yujf"/>
    <property name="password" value="yujf1992"/>
</bean>

<bean id="mySessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="myDataSource"/>
    <property name="mappingResources">
        <list>
            <value>User.hbm.xml</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <value>
            org.hibernate.dialect.MySQLDialect
        </value>
    </property>
</bean>

很明显是少了commons-dbcp和commons-pool这两个包。
你只是copy到lib下，有没有build path-->add to build path？
