我尝试使用 mysql,所以包括 mysql.jdbc,这些是我的休眠设置。

<property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>
</session-factory>
</hibernate-configuration>
但是当我尝试连接数据库时,我得到了这个错误:
Unable to connect: Cannot establish a connection jdbc:mysql://localhost:3306/mydbname using apache.org.derby.jdbc.ClientDriver(Unable to find a suitable driver)
我什至不使用 derby 为什么会出现此错误?
