Answer 1

你的课程路径上需要mysql-connector-*.jar

Answer 2

尝试使用这些属性值：

<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
 ...
<property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>

检查hibernate3.jar是否也在您的路径中。

Answer 3

JDBC Driver class not found: com.jdbc.mysql.driver

完全限定类名称区分大小写。您需要在Hibernate配置文件中使用大写com.mysql.jdbc.Driver声明D，而不是com.mysql.jdbc.driver使用小写d。

找不到JDBC驱动程序类
