This error occurs because ReactiveCrudRepository is not supported by Spring Data JPA.

According to this Spring Data official blog bost (November 23, 2016), only MongoDB, Cassandra and Redis are supported for now:

Support for reactive data access

The most significant additions that made it into the milestone is the addition of support for reactive data access for selected stores. This means: reactive Spring Data repositories and templates for MongoDB, Cassandra and Redis.

According to a comment by Mark Paluch on jira.spring.io JPA will not be supported.

We won't provide reactive support for Spring Data JPA. Exposing a reactive API creates the expectation of being reactive but that's the exact opposite for JPA. JPA is blocking, requires a transaction context, that is bound to a thread and the whole JDBC backend follows a blocking approach as well. Providing a reactive API for relational databases could still make sense in a context of reactive/asynchronous database drivers.
