在Spring Boot中创建多个数据源和架构

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

1. 有两个数据源的地方spring.jpa.hibernate.ddl-auto=create似乎无法在我的Spring Boot应用程序spring.jpa.generate-ddl=true中工作，请立即执行此操作

2. 我无法为每个数据源选择自动创建策略。我宁愿为数据源一创建模式，而仅在第二个DB中将数据源为二使用创建的模式。

任何机构都知道如何解决这些问题？注意如果可能的话，我不想完全放弃自动配置。我什至还不知道，hibernate是否能够在一个持久性单元中初始化架构。
