我使用Vert.x工具包来创建反应式应用程序,支持MySQL和Postgres等关系数据库.我知道Spring为像Cassandra和Mongo这样的NoSQL DB提供了反应支持,但是他们是否愿意为关系数据库提供相同的支持？

我需要使用Oracle数据库和Spring,我可以轻松选择Spring Data JPA,但我的所有程序都应该是被动的.

就像Spring支持Couchbase和Mongo的Reactive Repositories,如本链接所述,请帮我启用Oracle的Reactive Repositories.

我已经尝试从存储库接口扩展ReactiveCrudRepository,但由于Spring Data JPA没有实现反应式API方法,因此失败了.

问题:通过扩展ReactiveCrudRepository来尝试弹簧网以及弹簧数据.我收到以下错误:
