出现此错误：-“java.sql.SQLException：找不到合适的驱动程序”。当我使用 Hibernate Config 进行反向工程时。我的数据库

唐纳拉卡

我正在尝试使用带有 Eclipse IDE 的 Hibernate 配置来反转 Engeneer 我的简单 MYSQL DB。但是出现以下错误。

java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3307/client1_db

我经历过类似的问题。这是一个 Marven Web 项目，我可以看到 MYSQL_connector_java_5.1.34.jar 在 Marven Dependencies 库下。有人建议“找不到合适的驱动程序”意味着驱动程序正在加载，但数据库连接有问题。我尝试连接到本地主机，并且数据库是使用 MySQL 工作台创建的，并且可以访问。我什至尝试使用 myphp admin 并且可以访问数据库。

hibernate.cfg.xml 文件

    <?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>
        <!-- Database connection settings -->
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/bookshop</property>
        <property name="connection.username">root</property>
        <property name="connection.password">password</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <!-- Drop the existing tables and create new one -->
        <property name="hbm2ddl.auto">create</property>

    </session-factory>
</hibernate-configuration>

然后我尝试使用不同的服务器端口 3307，如下所示。还是一样的错误。

<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost:3307/client1_db</property>
        <property name="connection.username">root</property>
        <property name="connection.password">password</property>
