        <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>

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

        <!-- <mapping package="com.redpass.entities"/>
        <mapping class="com.redpass.entities.MyReference"/> -->
    </session-factory>
</hibernate-configuration>

我应该添加这个:

configuration.configure("hibernate.cfg.xml");
        return configuration
                .buildSessionFactory(new StandardServiceRegistryBuilder()
                        .applySettings(configuration.getProperties())
                        .build());

到我的 HibernateUtil 类，告诉我们要使用 hibernate.cfg.xml 文件进行配置并映射类，如下所示:

<mapping class="com.redpass.entities.Partie"/>
<mapping class="com.redpass.entities.Societe"/>
