Thank you for posting this issue.
Currently RelMongo is compatible with spring-boot 1.5.X versions so with spring-data-mongodb 1.10.X.
In the version 2.0 the compatibility will be ported to spring-boot 2.X and compatible spring-data-mongo-dependency.

For the moment you can solve your problem by excluding the spring-data-mongodb from spring boot dependencies and add this dependency to your project :
``

   <dependency>
                    <groupId>org.springframework.data</groupId>
                    <artifactId>spring-data-mongodb</artifactId>
                    <version>1.10.11.RELEASE</version>
  </dependecy>

Hi a new pre-release ( 2.0.0-RC1) to work with spring-boot 2.X.X was published please see compatibility matrix

Thanks, I am able to bring the app up using either 1.5.3 or 2.0.2 when following the compatability matrix.
