Why is data not written to the table using Hibernate?

Question

Java

I can not understand why when using the save method of the current session, data is not written to the database?
Where could I be wrong?
table:

starting point:

public class ClassForTesting {

    public static void main(String[] args) {
        DepartmentDAO dao = new DepartmentDAO();
        Department department1=new Department("DepartmentName1");
        Department department2=new Department("DepartmentName2");

        dao.persist(department1);
        dao.persist(department2);

        department1.setName("changedDapertmentName1");
        dao.update(department1);


    }
}

dao:

public class DepartmentDAO implements ModelDAO<Department, Integer> {
    private Session currentSession;
    private Transaction currentTransaction;

    public DepartmentDAO() {
    }

    public Session openCurrentSession() {
        currentSession = getSessionFactory().openSession();
        return currentSession;
    }

    public Session openCurrentSessionWithTransaction() {
        currentSession = getSessionFactory().openSession();
        currentTransaction = currentSession.getTransaction();
        return currentSession;
    }

    private static SessionFactory getSessionFactory() {
        Configuration configuration = new Configuration().configure();
        StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder()
                .applySettings(configuration.getProperties());
        SessionFactory sessionFactory = configuration.buildSessionFactory(builder.build());
        return sessionFactory;
    }

    public void closeCurrentSession() {
        currentSession.close();
    }

    public void closeCurrentSessionwithTransaction() {
        currentTransaction.commit();
        currentSession.close();
    }

    public Session getCurrentSession() {
        return currentSession;
    }

    public void setCurrentSession(Session currentSession) {
        this.currentSession = currentSession;
    }

    public Transaction getCurrentTransaction() {
        return currentTransaction;
    }

    public void setCurrentTransaction(Transaction currentTransaction) {
        this.currentTransaction = currentTransaction;
    }

    public void persist(Department entity) {
        openCurrentSession();
        getCurrentSession().save(entity);
        closeCurrentSession();
    }

Essence:

@Entity
public class Department {
    @Id 
     @GeneratedValue
    private Integer id;
    @Column(name="name")
    private String name;

hibernate.cfg.xml:

Answer 1

everything was decided by adding a session and a transaction before and after the start of the steal method
