在Spring Boot中迁移到Hibernate 5.2.6后，EntityManagerFactory不能为null

spring-boot

从Hibernate 5.0.11迁移到5.2.6.Final后，我在Spring
Boot应用程序中使用了Hibernate。最终，我获得EntityManagerFactory不能为null，这是我的代码

我的hibernate配置

@Configuration
@EnableTransactionManagement
public class DatabaseConfiguration {

    @Bean
    public HibernateJpaSessionFactoryBean sessionFactory() {
        return new HibernateJpaSessionFactoryBean();
    }

    @Bean
    public HibernateTransactionManager transactionManager(@Autowired SessionFactory sessionFactory) {
        HibernateTransactionManager transactionManager = new HibernateTransactionManager();
        transactionManager.setSessionFactory(sessionFactory);
        return transactionManager;
    }

}

我的存储库类

@Repository
public class GenericRepository{

    @Autowired
    private SessionFactory sessionFactory;

}

例外是这个

我将配置更改为此创建了sessionfactory

    @Inject
    public DataSource dataSource;


    @Inject
    public JpaProperties prop;


    @Bean("sessionFactory")
    @Primary
    public LocalSessionFactoryBean getSessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource);
        sessionFactory.setPackagesToScan(new String[] { "org.roshan" });
        sessionFactory.setAnnotatedPackages(new String[] { "org.roshan" });
        sessionFactory.setHibernateProperties(getHibernateProperties());
        return sessionFactory;
    }


    private  Properties getHibernateProperties() {
        Properties p = new Properties();
        p.putAll(prop.getProperties());
        p.put(AvailableSettings.HBM2DDL_AUTO, prop.getHibernate().getDdlAuto());
        return p;
    }
