在運行時以編程方式定義和刪除Spring Boot/Spring JPA數據源？

我需要在運行時動態創建Spring Boot Datasources。有人知道怎麼做嗎。有效，我需要做這個需求：在運行時以編程方式定義和刪除Spring Boot/Spring JPA數據源？

spring: 
    datasource: 
    url: jdbc:h2:mem:testdb1; 
    username: sa 
    password: 
    driver-class-name: org.h2.Driver 
    platform: h2 

spring: 
    datasource: 
    url: jdbc:h2:mem:testdb2; 
    username: sa 
    password: 
    driver-class-name: org.h2.Driver 
    platform: h2

...

spring: 
    datasource: 
    url: jdbc:h2:mem:testdbN; 
    username: sa 
    password: 
    driver-class-name: org.h2.Driver 
    platform: h2

的思考？

試試下面的方法來創建數據源編程

DriverManagerDataSource dataSource = new DriverManagerDataSource(); 
dataSource.setUrl("jdbc:h2:mem:testdb1"); 
dataSource.setUsername("sa"); 
dataSource.setPassword(""); 
dataSource.setDriverClassName("org.h2.Driver");
