Boa tarde caros!
Estou tendo problemas para buscar dados no database via Hibernate. As classes estão com a notação correta, como pode ser visualizado abaixo:
//Entidade//
package futebol.entities;
import java.util.List;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;
@Entity
@Table(name = "times")
public class TimeEntity {
@Id @GeneratedValue
private int id;
@Column(name="nome", nullable=false)
private String nome;
@Column(name="apelido", nullable=false)
private String apelido;
@OneToMany
List<JogadorEntity> jogador;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public String getApelido() {
return apelido;
}
public void setApelido(String apelido) {
this.apelido = apelido;
}
public List<JogadorEntity> getJogador() {
return jogador;
}
public void setJogador(List<JogadorEntity> jogador) {
this.jogador = jogador;
}
}
//Repository//
package futebol.repository;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.Query;
import futebol.entities.TimeEntity;
public class TimeRepository {
private EntityManager gerenciador;
public TimeRepository(EntityManager gerenciador)
{
this.gerenciador = gerenciador;
}
public void adiciona(TimeEntity t)
{
this.gerenciador.persist(t);
}
public TimeEntity busca(int id)
{
return this.gerenciador.find(TimeEntity.class, id);
}
@SuppressWarnings("unchecked")
public List<TimeEntity> buscaTodos()
{
Query query = gerenciador.createQuery("SELECT t FROM TimeEntity t");
return query.getResultList();
}
}
O erro pode ser visualizado abaixo:

Nessa linguagem HDL, eu tentei de tudo jeito mas aparece que classe/tabela não foi mapeada…
Como resolver isso?
Muito obrigado,
Att, André Vieira.
