Hibernate ORM with Hibernate OGM (MySQL with Neo4J)

Question

Is it possible to create a single application with Hibernate ORM and OGM? I created an application and I am getting issues for multiple JPA in a single application. I resolved this by changing the sessionFactory name for both JPA, still there is a conflict between two JPA. Below is the exception:

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.data.neo4j.transaction.SharedSessionCreator#0': Unsatisfied dependency expressed through method 'createSharedSession' parameter 0: Could not convert argument value of type [org.hibernate.internal.SessionFactoryImpl] to required type [org.neo4j.ogm.session.SessionFactory]: Failed to convert value of type 'org.hibernate.internal.SessionFactoryImpl' to required type 'org.neo4j.ogm.session.SessionFactory'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'org.hibernate.internal.SessionFactoryImpl' to required type 'org.neo4j.ogm.session.SessionFactory': no matching editors or conversion strategy found

Other error I am facing is:

Overriding bean definition for bean 'sessionFactory' with a different definition: replacing [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=databaseConfig; factoryMethodName=hibernate5SessionFactoryBean; initMethodName=null; destroyMethodName=(inferred); defined in class path resource [org/company/nc/config/DatabaseConfig.class]] with [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=persistenceContext; factoryMethodName=sessionFactory; initMethodName=null; destroyMethodName=(inferred); defined in class path resource [org/company/nc/config/PersistenceContext.class]]

I'm one of the developer of the Hibernate OGM project.

I think something is not right in the dependencies. From your question it seems you are interested in Hibernate OGM but your pom is using Neo4j OGM.

If you want to use Hibernate ORM with Hibernate OGM, your pom should contain the following dependency:

    <dependency>
        <groupId>org.hibernate.ogm</groupId>
        <artifactId>hibernate-ogm-neo4j</artifactId>
        <version>${hibernateOgmVersion}</version>
    </dependency>

This will also include the required drivers and neo4j embedded. For more details about the configuration I'll let you to the documentation.

I think you should update the pom or update the question.
