【问题讨论】：

角色对象是否映射到休眠中？您可以发布 Role 类。

我发布了角色类

Id 说 init 在创建表之前完成。您可以删除 PostConstruct 并运行它，然后尝试从控制台访问 Role 表吗？可以使用资源目录下的insert.sql来设置数据

您需要验证您在 application.properties 中提供的用户是否具有插入数据库的权限。

好的。但是我应该如何验证用户“sa”是否具有必要的权限？

【参考方案1】：

这似乎是与 sql 相关的错误，而不是 JPA 错误。一个好的方法是使用与连接字符串相同的凭据登录到您的 rdbms，并检查与您的实体对应的表是否可以使用您当前的用户进行查询。

您可以使用 dbeaver 来执行此操作，因为它支持 hsqldb。

【讨论】：

好的。但是我应该如何验证用户“sa”是否具有必要的权限？

授予“sa”权限并确保发出关闭“SHUTDOWN”

username "sa" 是 hsqlDB 中的默认用户，我将其用作“in memory DB”进行测试，它具有所有特权。当我最小化 configForJpa 并让 hibernate 创建它的魔术表时，但我得到另一个错误： Hibernate: alter table user_roles drop constraint 我发布了控制台和 configForJpa2

对我来说，同一组 application.yml 属性非常适合不同的项目。
