Hibernate not updating database (despite it commits and reads it)

Question

I have no exceptions and everything seems to be okay, but after inserting some data into the database it doesn't persist. I don't know if I need some specific annotation or I failed at some Spring configuration.

Entity bean:

@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 script for the table:

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

Imagen repository:

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

Imagen service:

@Service
public class ServicioImagen {

    @Autowired RepositorioImagen repo;

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

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

And controller:

@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));
    }

}

I inserted some default records in the table when I created the database, and the method getAll() retrieves them nice, but when I save() a new bean, it doesnt persist in the database (getAll() retrieves the same information as before). I read in this answer to turn on the logger, and then I discovered that Hibernate even commits the query. I don't know what more to do, here's the log of the insert:

I also noticed that the query commited after the conection closing (timestamp 2020-03-07 18:33:55.720 for Ctrl+F), I don't know if it has anything to do with the persistence.

Actually it's a button action of JavaFX, but I'm 100% sure it's being invoked . I didn't added that to the question because it's meaningless. — Niedon, Mar 07 '20 at 18:03
You're not sure the function is invoked and you think it's irrelevant? — Andronicus, Mar 07 '20 at 18:16
No, I'm 100% sure the function was invoked, I said that the function being a JavaFX onAction method is meaningless to add to the question. — Niedon, Mar 07 '20 at 18:21

This is because the transaction was not closed before you tried to fetch the data from database.

Try use saveAndFlush(); instead of save();

I tried it, but it throws an exception: `Caused by: org.springframework.dao.InvalidDataAccessApiUsageException: no transaction is in progress; nested exception is javax.persistence.TransactionRequiredException: no transaction is in progress` – Niedon Mar 07 '20 at 18:05
Try also use `@Transactional` at your service. – CodeSlave Mar 07 '20 at 18:10

Annotating the service with `@Transactional` is a huge code smell – Andronicus Mar 07 '20 at 18:13
Same, I tried both `@Transactional` annotations (`javax` and `springframework`) and still throws the exception, even adding/removing `@EnableTransactionManagement` to the Spring config file. Log tells it rolled back after the exception, hopefully. – Niedon Mar 07 '20 at 18:18
@Andronicus no, it does fine, here are the log messages: `rolling back` - `Preparing to rollback transaction via JDBC Connection.rollback()` - `Transaction rolled-back via JDBC Connection.rollback()` - `LogicalConnection#afterTransaction` - `Releasing JDBC resources` - `re-enabling auto-commit on JDBC Connection after completion of JDBC-based transaction` – Niedon Mar 07 '20 at 18:31
method of the service* – CodeSlave Jun 04 '22 at 08:12

I finally made it work, I don't know why, but I'm posting how I did it in case it helps someone.

My configutarion file looked like this:

@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;
       }
}

I made some changes:

@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();
       }
}

As CodeSlave said, I needed to flush(), and then I recieved that exception, but after deleting the LocalSessionFactoryBean bean all started working. I have tried even deleting EntityManager and EntityManagerFactory beans and it keeps working fine, but I don't know if I should keep them or delete them. I would like to give a more clear answer to this but I'm new in Hibernate, I guess I was unconsciously configuring a transaction manager that Hibernate/Spring wasn't going to use or something like that.

Hibernate not updating database (despite it commits and reads it)
