Cannot load JDBC driver class

整合ssm框架，出现这个错误：

Cannot load JDBC driver class '${jdbc.driverClassName}'

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName" value="${jdbc.driverClassName}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${username}" />
		<property name="password" value="${password}" />
	</bean>

 

这里是读取属生文件中的配置信息

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" name="sqlSessionFactorys">  
	    <property name="configLocation" value="classpath:mybatis-config.xml" />  
	    <property name="dataSource" ref="dataSource" />  
	</bean>  

	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="annotationClass" value="org.springframework.stereotype.Repository"/>
        <property name="basePackage" value="com.uuider.studentmanager"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactorys"/>
        <!-- <property name="sqlSessionFactory" ref="sqlSessionFactory"/> 如果使用这个，则会报错-->
    </bean>
