Hibernate не вставляет данные в БД

Question

У меня есть простой проект гибернации, который должен вставить и выбрать запись из базы данных. Я установил Bean, интерфейс DAO и реализовал его в классе DAOImple.

Однако он не вставляет данные в таблицу. Основной выводит новый идентификатор, но по-прежнему в таблице не создается запись.

Это код, который у меня есть:

Program. java

import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class Program {

    public static void main(String args[])
    {
        AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(SpringConfigurations.class);
        
        ProductDAO dao = context.getBean(ProductDAO.class);
        
        System.out.println("Creating product");
        dao.create(new Product("Chocklate", 17.9f));
        System.out.println("Product created successfully");
        
        
        System.out.println("***********************");
        for(Product p : dao.findAll())
        {
            System.out.println(p);
        }
    }
}

        transactionManager.setSessionFactory(getSessionFactoryBean().getObject());
        
        return transactionManager;
    }
    
    public DriverManagerDataSource getDataSource()
    {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setUrl(getHibernateProperties().getProperty("connectionString"));
        return dataSource;
