春天与春天JPA:按需创建数据库架构和表

在JPA/Spring中是否有可能在运行时创建/删除具有自定义名称和相应表(由@Entity批注提供)的数据库模式，例如用户何时按下按钮?

Is there any possibility in JPA/Spring to create/delete a database schema with a custom name and according tables (given by @Entity annotations) at runtime, e.g. when the user presses a button?

我只知道javax.persistence.schema-generation属性，这些属性在我的应用程序启动时执行，并使用预定义的架构名称.

I only know about the javax.persistence.schema-generation properties, which are executed at startup of my application and use a predefined schema name.

我正在寻找的简短(简化)示例:

A short (and simplified) example of what I am looking for:

假设我有两个实体，Dog和Cat.当用户按下按钮时，将创建一个具有两个表Dog和Cat的新架构animals1.现在，所有查询都转到架构animals1.当用户第二次按下按钮时，将创建具有两个表的不同架构animals2，并且所有查询现在都进入animals2.

Let's say I have two entities, Dog and Cat. When the user presses a button, a new schema animals1 with two tables Dog and Cat is created. All queries now go to schema animals1. When the user presses the button a second time, a different schema animals2 with the two tables is created, and all queries now go to animals2.

我认为我在春季可以做些魔术，但是我不知道从哪里开始.我将不胜感激.

I assume there is some magic I can do in Spring, but I have no clue where to start. I would be grateful for any hints.
