Question

我有一个非常小的项目，我使用Mybatis，Spring仅用于依赖项注入，commons-DBCP用于连接池。由于我使用的是DBCP，Mysql和Mybatis，因此我觉得不必添加Spring-JDBC依赖项，也没有在pom.xml中添加该依赖项。

但是，我遇到了异常，寻找解决方案建议添加Spring-JDBC依赖项。这听起来不对，因为我只需要添加所需的依赖项，并且在我的项目中没有引用任何Spring-JDBC类。

这是我的应用程序上下文xml。

    </bean>

    <bean id="dataSource" destroy-method="close"

        <property name="sqlSessionFactory" ref="sqlSessionFactory" />
        <property name="mapperInterface" value="com.ws.dao.UserDao" />
    </bean>
</beans>

这是堆栈跟踪：
