NoUniqueBeanDefinitionException: Es ist keine qualifizierende Bean des Typs [javax.persistence.EntityManagerFactory] definiert: erwartete einzelne übereinstimmende Bean
Ich habe 2 separate Datenbanken und versuche, in Repositories darauf zuzugreifen. Leider erhalte ich die folgende Ausnahme.
Things habe ich versucht
Habe versucht,one der Bohne als Primary.benutzt haben PersistenceContext wie im Code unten zu sehen.Meine ExceptionTrace

Myorder controller das ist einfach Autowiring Repository
@RestController
@RequestMapping("/Order")
public class OrderController {
@Autowired
private OrderRepository nextGenorder;
Meine Bestellung Repository ha
@Repository
public class OrderRepository extends AbstractRepository<Order> implements
OrderRepositoryInterface {
private static final String SELECT_QUERY = "select p from v_orders p";
@PersistenceContext(name = "nextGenEntityManagerFactory")
private EntityManager nextGenEntityManagerFactory;;
public EntityManager getEntityManager() {
return nextGenEntityManagerFactory;
}
public void setEntityManager(EntityManager entityManager) {
this.nextGenEntityManagerFactory = entityManager;
}
public List<Order> selectAll() {
javax.persistence.Query query = nextGenEntityManagerFactory
.createQuery(SELECT_QUERY);
List<Order> order = query.getResultList();
return order;
}

Ich habe versucht, in @ zu debugg PersistenceAnnotationBeanPostProcessor aber wurde bald verloren.
