我已经创建了我的模型 类。并用@Entity 注释它们。我也设置了 hbm2ddl 属性 来创建。每当我尝试将它部署在服务器中时，它仍然不会生成表。而且也没有错误。
我试图搜索 google 上的所有解决方案，尝试了很多但没有奏效。
将感谢您的帮助
您似乎没有添加模型的类路径 类。您可以在 sessionFactory.
中添加此内容 </property> 标签后，添加
<mapping class="<full class path>"/>
例如 - <mapping class="com.hibernate.UserDetails">
此外，如果正在显示 SQL 语句，请检查您的控制台。如果 Table 正在创建然后删除，请替换
<prop key="hibernate.hbm2ddl.auto">create-drop</prop>
和<prop key="hibernate.hbm2ddl.auto">create</prop>
或 <prop key="hibernate.hbm2ddl.auto">update</prop>
因为
create-drop: Creates a Schema and then DROP the schema when the SessionFactory is closed explicitly, typically when the application is stopped.
update: Creates the Schema and Updates if there are any changes in Model classes. Its a safer option to use as database doesn't get Deleted or data is not affected on Server Restart.
create: creates the schema, destroying previous data. (Use it only the First time or may result in all data being destroyed the next time you restart your server.
