Olá ,sou iniciante em programação ,e estou seguindo umas video-aulas no youttube.
Estou passando por uma dificuldade ,que é para fazer a persistência dos dados,eu criei o Banco no MYSQL(Workbench) e o projeto não está criando as tabelas no BD ,estou usando o Maven,Hibernate com JPA.
Estou seguindo esta video-aula…

Minha classe de teste
package br.com.ricardo;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import br.com.ricardo.entidade.Usuario;
public class TestHibernate {
public static void main(String[] args) {
// Fabrica de EntityManager
EntityManagerFactory emf = Persistence.createEntityManagerFactory("laboratorio");
// Gerenciador de Entidades
EntityManager em = emf.createEntityManager();
// Criando o objeto a ser persistido
Usuario user = new Usuario();
user.setNome("Gambiarra");
user.setLogin("R");
user.setSenha("123456");
// inicia a transa��o
em.getTransaction().begin();
// Prepara a instru��o SQL
em.persist(user);
// Grava no banco//Fazendo a persistencia no banco
em.getTransaction().commit();
}
}
O nome do banco que criei foi fabricaweb2db
Gostaria muito da ajuda de vocês…
