【问题描述】：
我想将数据保存到 postgresql 中的表中。我正在使用spring boot + postgresql 和hibernate。我的应用程序没有任何错误，但它没有在数据库中创建表。
这是我的控制器类

我想将数据保存到 postgresql 中的表中。我正在使用 spring boot + postgresql 和 hibernate。我的应用程序没有任何错误，但它没有在数据库中创建表。
【问题讨论】：
-
在您的 hibernate.hbm2ddl.auto 中，将其设置为
update。另外，如果你有 Postgresql，为什么要使用 MySQl 方言，去 PostgreSQL9Dialect。 -
我试过它不起作用
-
org.hibernate.dialect.PostgreSQLDialect 我现在正在使用这种方言但仍然没有创建表
-
您可以发布您的
hibernate.cfg.xml文件吗？ -
通过编辑您的主帖发布更新的代码。另外，您在模型中添加了哪些列？正如拉曼所说，你能发布hibernate.cfg.xml吗？
