Unable to use Spring Data MongoDB + Spring DataJPA together with SpringBoot

When I try to use Spring Data JPA and Spring Data MongoDB together with SpringBoot it is assuming my Mongo Entities also JPA entities and throwing errors.

I have Person JPA entity and PersonRepository which extends JpaRepository. And I have User Mongo Entity and UserRepository which extends MongoRepository.

When I start the application I am getting the following error:

Caused by: java.lang.IllegalArgumentException: Not an managed type: class com.sivalabs.app.mongoentities.User
    at org.hibernate.jpa.internal.metamodel.MetamodelImpl.managedType(MetamodelImpl.java:219)

    ... 66 more

Is there any work around for this?

You should put your Mongo and JPA entities in separate packages (it looks like you've already done that) and then use @EnableMongoRepositories(basePackageClasses=SomeMongoEntity.class) and @EnableJpaRepositories(basePackageClasses=SomeJpaEntity.class) so that Spring Data knows where to find the Mongo and JPA entities respectively. You can see these annotations in action in Spring Boot's MixedMongoRepositoriesAutoConfigurationTests.
