Bom dia pessoal, postei umas duvidas ontem e fui prontamente atendido por alguns colegas, graças a ajuda deles consegui resolver os problemas aqui no meu projeto.
Bem hoje, meu projeto ja esta quase funcionando exceto por uma coisa, ele cria a tabela no banco, mas eu não consigo inserir nada, fica dando erro de mapeamento, mas eu acho que fiz tudo certo conforme vocês poderão ver abaixo.
package br.gera.dominio;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Table(name=“Pergunta”)
@Entity
public class Pergunta {
@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE)
private long id;
private String descricao;
private String[] alternativa;
private String resposta;
public Pergunta(){
}
public Pergunta( long id, String descr, String[] alterna, String resp){
this.id = id;
this.descricao = descr;
this.alternativa = alterna;
this.resposta =resp;
}
//getters and setters
}
hibernat.cfg.xml
<?xml version="1.0" encoding="UTF-8"?> org.gjt.mm.mysql.Driver jdbc:mysql://127.0.0.1:3306/quiz root 123456 org.hibernate.dialect.MySQL5InnoDBDialect true true true update<mapping class="/br/gera/dominio/Pergunta"/>
</session-factory>
