olá Carlos,

• Como que está e onde está o seu persistence.xml?
• Verifique se o nome do seu persistence-unit dentro do persistence.xml está correto. -Verifique se todas as libs do hibernate foram baixadas.

Está no /src/META-INF

Não tem nada errado com o arquivo, pois funciona sem alteração nenhuma, quando utilizo as libs do Hibernate 4.x, que é utilizado no curso.

Ao mudar a versão das libs que recebo o erro.

Estou passando pelo mesmo problema do Carlos Vinicius... Ao adicionar as bibliotecas do hibernate 5.2 recebo o Exception: No Persistence provider for EntityManager named financas.

Quando uso o a versão 4.3 o projeto funciona normal.

Até o momento não consegui usar a versão 5.2 do hibernate...

Olá, Carlos e Maurício!

Tentem utilizar o seguinte provider dentro de persistence-unit no arquivo persistence.xml:

org.hibernate.jpa.HibernatePersistenceProvider

Alterei mas o erro continua:

Main que rodei:

package financas.teste;

import javax.persistence.EntityManager;
import javax.persistence.TypedQuery;

import financas.util.JPAUtil;

public class TesteMovimentacaoConta {

    public static void main(String[] args) {
        EntityManager manager = new JPAUtil().getEntityManager();

        TypedQuery<Long> query = manager.createQuery("SELECT COUNT(m) FROM Movimentacao m", Long.class);

        System.out.println(query.getSingleResult());

        manager.close();
    }

}

JPAUtil:

package financas.util;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public class JPAUtil {

    private static EntityManagerFactory factory = Persistence.createEntityManagerFactory("financas");

    public EntityManager getEntityManager() {
        return factory.createEntityManager();
    }
}

Algo errado?

Esqueci de compartilhar o persistence.xml:

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <!-- Implementação do JPA, no nosso caso Hibernate -->

        <!-- Aqui são listadas todas as entidades -->

            <property name="hibernate.format_sql" value="true" />
        </properties>
    </persistence-unit>

</persistence>

Oi Carlos,

Nas suas entidades Conta e Movimentacao tem como garantir IDENTITY como estratégia de geração da chave primaria?

Algo assim:

@Entity
public class Conta {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;

   //outros atributos omitidos

A mesma coisa na classe Movimentacao.

Tbm garante que não há nenhuma tabela criada e apague elas no banco.

Abs, Nico

Ola Mateus e Nico! As dicas funcionaram, agora estou conseguindo usar a ver 5.2 do hibernate, era o provider mesmo.

Obrigado.

Até.

Com a alteração sugerida pelo Nico consigo rodar PopulaConta OU PopulaMovimentacao.

Não consigo rodar as duas. Se rodo a PopulaConta, e depois tento rodar PopulaMovimentacao, recebo o erro:

Segue todo meu projeto: https://mega.nz/#!WFRACLrY!kduhxw_JU--UM5yash3TcoXxSZnzKihlLP3KhA2l9d8

Oi Carlos,

isso é um bug do Hibernate (fogo!!), introduzido na versao 5.2:

https://hibernate.atlassian.net/browse/HHH-10802

Aconselho usar as bibliotecas do curso, essas foram testados.

abs

instalei o Wildfly 10, que ja vem com as bibliotecas nativas, quando inicio o servidor tudo roda perfeitamente, porem ao testa-lo com o arquivo main, recebo a menssagem: "No Persistence provider for EntityManager named ..." - O persistence.xlm esta no lugar certo. podem me majudar?

persistence.xml

<?xml version="1.0" encoding="UTF-8"?>

org.hibernate.jpa.HibernatePersistenceProvider br.com.wolf.modelo.Conta

Conta.java

package br.com.wolf.modelo;

import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.SequenceGenerator;

@Entity @SequenceGenerator(name = "SEQ_Conta", sequenceName = "SEQ_Conta", initialValue = 1) public class Conta {

@Id @GeneratedValue(strategy = GenerationType.AUTO, generator = "SEQ_Conta") private Integer idConta; private String emailConta; private String senhaConta;

public Integer getIdConta() { return idConta; }

public String getEmailConta() { return emailConta; }

public void setEmailConta(String emailConta) { this.emailConta = emailConta; }

public String getSenhaConta() { return senhaConta; }

public void setSenhaConta(String senhaConta) { this.senhaConta = senhaConta; }

}

TesteJPA.java

package br.com.wolf.run;

import javax.persistence.EntityManager; import javax.persistence.EntityManagerFactory; import javax.persistence.Persistence;

import br.com.wolf.modelo.Conta;

public class TesteJPA {

public static void main(String[] args) {

double inicio = System.currentTimeMillis();

EntityManagerFactory emf = Persistence.createEntityManagerFactory("wolfportal"); EntityManager em = emf.createEntityManager();

Conta conta = new Conta(); conta.setEmailConta("teste"); conta.setSenhaConta("123");

em.getTransaction().begin();

em.persist(conta);

em.getTransaction().commit(); em.close();

double fim = System.currentTimeMillis(); System.out.println("Executado em: " + (fim - inicio) / 1000 + "s");

} }

==================

Erro

Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named wolfportal at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:61) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:39) at br.com.wolf.run.TesteJPA.main(TesteJPA.java:18)

Oi Vagner,

esse post já foi resolvido, tem como criar um novo por favor?

Obrigado, Nico
