Spring Boot中的多个数据源和模式创建

我正在使用Spring Boot . 我终于设法设置了两个数据源，但现在我面临另一个问题 .

• 有两个数据源 spring.jpa.hibernate.ddl-auto=create 似乎停止在我的 Spring 季启动应用程序中工作，只有 spring.jpa.generate-ddl=true 现在就完成工作

• 我无法为每个数据源选择自动创建策略 . 我更愿意为数据源1创建模式，只使用第二个数据库中创建的模式和数据源2 .

任何机构都知道如何解决这些问题？注意我不想在可能的情况下完全丢弃自动配置 . 我还不知道，如果hibernate能够在一个持久性单元中初始化模式 .
