spring MVC + mybatis，如何配置ODBC数据源？

driver:sun.jdbc.odbc.JdbcOdbcDriver

db:jdbc:odbc:mydb

        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
        <property name="url" value="jdbc:oracle:thin:@xxx"/>
        <property name="username" value="xxxx"/>
        <property name="password" value="xxxx"/>
    </bean>



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

要加入mybatis-spring.jar
