To reproduce this issue, just @Autowire MongoOperations ops. This configuration works with 2.2.6.RELEASE without any issues.

The error is:

Consider defining a bean of type 'org.springframework.data.mongodb.core.MongoOperations' in your configuration.

Comment From: snicoll

MongoOperations is the imperative (non reactive) variant. The new MongoDB driver has harmonized their infrastructure with a clear split so that is expected. If you need the imperative variant, you need to add spring-boot-starter-data-mongodb.

I've polished the release notes to reflect that information.
