Hibernate не обновляет базу данных (несмотря на то, что фиксирует и читает ее)

У меня нет исключений, и все вроде бы нормально, но после вставки некоторых данных в базу они не сохраняются. Я не знаю, нужна ли мне какая-то конкретная аннотация c, или я потерпел неудачу в какой-то конфигурации Spring.

Бин сущности: 

@Entity
@Table(name="IMAGEN")
public class Imagen {

    @Id
    @Column(name="ID")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;

    @Column(name="NOMBRE",
            nullable = false)
    private String nombre;

    @Column(name="CATEGORIA",
            nullable = false)
    private String categoria;

    //Getters and setters...

SQL скрипт для таблицы: 

CREATE TABLE IMAGEN(
ID INTEGER IDENTITY PRIMARY KEY,
NOMBRE VARCHAR(64) NOT NULL,
CATEGORIA VARCHAR(32)
);

Репозиторий изображений: 

@Repository
public interface RepositorioImagen extends JpaRepository<Imagen,Integer> {}

Сервис изображений: 

@Service
public class ServicioImagen {

    @Autowired RepositorioImagen repo;

    public List<Imagen> getAll(){
        return repo.findAll();
    }

    public void saveImage(Imagen im) {
        repo.save(im);
    }

И контроллер: 

@Controller
public class Controlador {
    @Autowired private ServicioImagen servicioImagen;

    private void someMethod(){
        servicioImagen.getAll().forEach(e -> System.out.println(e));

        Imagen imagen = new Imagen();
        imagen.setNombre("SOMENAME");
        servicioImagen.saveImage(imagen);

        servicioImagen.getAll().forEach(e -> System.out.println(e));
    }

}

Я вставил некоторые записи по умолчанию в таблица, когда я создал базу данных, и метод getAll() получает их красиво, но когда я save() новый бин, он не сохраняется в базе данных (getAll() получает ту же информацию, что и раньше). Я прочитал этот ответ, чтобы включить регистратор, а затем обнаружил, что Hibernate даже фиксирует запрос. Я не знаю, что еще делать, вот журнал вставки:

Я также заметил, что запрос зафиксирован после закрытия соединения (отметка времени 2020-03-07 18:33:55.720 для Ctrl + F), я не знаю, связано ли это с постоянством.

Я наконец-то заставил это работать, я не знаю почему, но я пишу, как я это сделал, если кому-то это поможет.

Мой файл configutarion выглядел так: 

@Configuration
@EnableTransactionManagement
public class SpringConfig {
    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("org.hsqldb.jdbcDriver");

        String ruta = System.getProperty("user.home") + "\\path\\to\\my\\db";
        String url = "jdbc:hsqldb:file:" + ruta;
        dataSource.setUrl(url);

        dataSource.setUsername("SA");
        dataSource.setPassword("");

        return dataSource;

    }

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan("com.bcadaval.memefinder3020.modelo.beans");

        return sessionFactory;
    }



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


    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
          LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
          em.setDataSource(dataSource());
          em.setPackagesToScan("com.bcadaval.memefinder3020.modelo.beans");     
          JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
          em.setJpaVendorAdapter(vendorAdapter);
          return em;
       }
}

Я внес некоторые изменения: 

@Configuration
@EnableTransactionManagement
public class SpringConfig {
    @Bean
    public DataSource dataSource() { /* the same as before */}

    @Bean
    public EntityManager entityManager() {
        return entityManagerFactory().createEntityManager();
    }

    @Bean
    public EntityManagerFactory entityManagerFactory() {

          LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
          em.setDataSource(dataSource());
          em.setPackagesToScan("com.bcadaval.memefinder3020.modelo.beans");     
          JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
          em.setJpaVendorAdapter(vendorAdapter);
          em.setPersistenceUnitName("default");
          em.afterPropertiesSet();
          return em.getObject();
       }
}

Как CodeSlave сказал , мне нужно было flush(), а затем я получил это исключение, но после удаления всех компонентов LocalSessionFactoryBean начал работать. Я пытался даже удалить компоненты EntityManager и EntityManagerFactory, и они продолжают работать нормально, но я не знаю, следует ли мне их сохранить или удалить. Я хотел бы дать более четкий ответ на этот вопрос, но я новичок в Hibernate, я думаю, что я неосознанно настраивал менеджер транзакций, который Hibernate / Spring не собирался использовать, или что-то в этом роде.

Это потому, что транзакция не была закрыта до того, как вы попытались получить данные из базы данных.

Попробуйте использовать saveAndFlush(); вместо save();
