The issue is Hibernate does not allow an application to have more than 1 instance of an entity manager/entity manager factory like other JPA frameworks eg EclipseLink. For example I am able to create and use multiple instances in EclipseLink but not in Hibernate like so:

define

@Bean(name="entityManagerFactory")
public EntityManagerFactory entityManagerFactory()

@Bean(name="entityManagerFactoryNeo4j")
public EntityManagerFactory entityManagerFactoryNeo4j()

Use

@Autowired
@Qualifier("entityManagerFactory")
EntityManagerFactory emfMysql;

@Autowired
@Qualifier("entityManagerFactoryNeo4j")
EntityManagerFactory emfNeo4j;
