Erro com Hibernate

Assuntos Gerais
#1

Ola pessoa , olha eu mais uma vez enxendo o saco de vocês, bom vamos la, é o Seguinte estou começando com o Hibernate,
TENTANDO fazer um crud(inser,delete,update,read), porem não estou conseguindo.

Primeiramente quero postar meus arquivos e classe(estou tentado fazer um crud na tabela de fornecedor, bem ditático, pois a tabela tem apenas um campo - nome - estou usando mysql)

Tabela Fornecedor

fornecedor
nome - varchar

log4j.properties

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out

hibernate.properties


hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.connection.driver_class = com.mysql.jdbc.Driver
hibernate.connection.url = jdbc:mysql://localhost:3306/controleestoque

<hibernate-mapping>   
    <class name="Negocio.Fornecedor" table="fornecedor">   
        <id name="nome" column="nome" type="string">   
            <generator class="assigned"/>   
        </id>   
    </class>   
</hibernate-mapping>

Fabrica de Conexao

package Persistencia;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;

import Negocio.Fornecedor;

public class FabricaConexao {

	private static SessionFactory factory;
	
	public static Session getSession(){
		AnnotationConfiguration cfg = new AnnotationConfiguration();
		cfg.addAnnotatedClass(Fornecedor.class);
		factory = cfg.buildSessionFactory();
		return factory.openSession();
	}
	
	
}

FornecedorDAO

package Persistencia;

import java.util.List;

import org.hibernate.Session;


import Negocio.Fornecedor;

public class FornecedorDAO implements DAO<Fornecedor> {
	private Session session;
	
	public FornecedorDAO(){
		session = FabricaConexao.getSession();
	}
	
	
	@Override
	public void insert(Fornecedor forn) {
		session.save(forn);
	}
	
	
	@Override
	public void update(Fornecedor obj) {
		session.update(obj);
		session.flush();
	}

	@Override
	public void delete(Fornecedor obj) {
		session.delete(obj);
		session.flush();
	}


	@Override
	public List<Fornecedor> read() {
		return session.createCriteria(Fornecedor.class).list();
	}
}

Fornecedor

package Negocio;

public class Fornecedor {

	private String nome;

	public Fornecedor() {
	}

	public Fornecedor(String nome) {
		this.nome = nome;
	}

	public String getNome() {
		return nome;
	}

	public void setNome(String nome) {
		this.nome = nome;
	}
}

E por fim minha classe de teste

package Negocio;

import Persistencia.FornecedorDAO;

public class Teste {

	public static void main(String[] args) {
		Fornecedor f = new Fornecedor();
		f.setNome("Pedro");
		FornecedorDAO fDAO = new FornecedorDAO();
		fDAO.insert(f);
		

		
	}

}

Porem quando dou start no eclipse da o seguinte erro no console

Cara não deu tempo de fazer uma análise completa, mas o erro é que ele não está encontrando o mapeamento da classe Negocio.Fornecedor, pelo visto você está usando o hibernate annotations, mas não criou as anotações na classe Negocio.Fornecedor.
Essa classe deve implementar Serializable e pelo menos o mapeamento de @Entity e @Id.

veja:http://docs.jboss.org/hibernate/stable/annotations/reference/en/html/entity.html#entity-mapping

#3

Meu ingles é pessimo mais obrigado pela ajuda, é pelo que eu vi eu tabem axei que era erro no mapeamento porem não sei resolver
Então pessoal, alguem pode resolver meu problema ou postar um exmplo usando hibernate?

#4

Certo, suponho que o atributo “nome” seja a chave primária de sua tabela fornecedor, uma dica é quando usar annotations em hibernate procure usar sempre o mesmo nome, ou seja os atributos da classe com o mesmo nome dos campos da tabela, pois economizará trabalho, da mesma forma que voce fez nesse exemplo.

Então ficaria assim:

[code]package Negocio;

@Entity
public class Fornecedor implements Serializable {

@Id
private String nome;

public Fornecedor() {
}

public Fornecedor(String nome) {
	this.nome = nome;
}

public String getNome() {
	return nome;
}

public void setNome(String nome) {
	this.nome = nome;
}

}[/code]

#5

Também estou interessado em Hibernate, se alguem tiver
um projeto bem básicao de CRUD para deixar para galera estudar…

Seria bem legal ^^

Att. Jonas

#6

Endenti, mais no caso de não usar anotação usar XML para fazer o relacionamento dos campos como ficaria?

MUITO OBRIGADO

Pessoal mudei minha fabrica de conexao

Por favor pessoal me ajude

Se você está começando agora, sugiro que vá de annotations, que é mais limpo, e mais fácil de encontrar problemas, quando aprendi annotations tirei o xml de minha cabeça, mas o mapeamento da classe fornecedor em xml é do jeito que você postou.
Não recomendo usar a String nome como chave primária, pois um fornecedor poderá mudar seu nome e te criar um problemão, sugiro usar um número.

#9

Ola mrrbigu , primeiramente quero agradecer pela atenção.

Então eu quero configurar via html , para eu entender por didatica mesmo, e tbm estou usando uma string copm chave primaria somente porque é para teste ou seja quero ver como funciona, mais da o seguinte erro que postei,

Por favor alguem mais para ajudar?

OBRIGADO

#10

Certo, esse erro diz especificamente que ele não está encontrando o arquivo Fornecedor.hbm.xml, poste seu arquivo hibernate.cfg.xml para vermos como está.

#11

mrrbigu

Olha eu tenho o arquivo hibernate properties

hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.connection.driver_class = com.mysql.jdbc.Driver
hibernate.connection.url = jdbc:mysql://localhost:3306/controleestoque
hibernate.connection.username = root
hibernate.connection.password =

hibernate.show_sql = true

hibernate.format_sql = true

e a fabrica de conexao

package Persistencia;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;



public class FabricaConexao {

	private static SessionFactory factory;
	
	public static Session getSession(){
		Configuration  cfg = new Configuration();
		cfg.addClass(Negocio.Fornecedor.class);
		factory = cfg.buildSessionFactory();
		return factory.openSession();
	}
	
	
}

e a classe DAO

package Persistencia;

import java.util.List;

import org.hibernate.Session;


import Negocio.Fornecedor;

public class FornecedorDAO implements DAO<Fornecedor> {
	private Session session;
	
	public FornecedorDAO(){
		session = FabricaConexao.getSession();
	}
	
	
	@Override
	public void insert(Fornecedor forn) {
		session.save(forn);
	}
	
	
	@Override
	public void update(Fornecedor obj) {
		session.update(obj);
		session.flush();
	}

	@Override
	public void delete(Fornecedor obj) {
		session.delete(obj);
		session.flush();
	}


	@Override
	public List<Fornecedor> read() {
		return session.createCriteria(Fornecedor.class).list();
	}
}

ESSE ARQUIVO QUE VC FALOU EU NÃO TENHO, NAO SERIA O MSM DA CLASSE QUE FABRICA CONEXAO? SE NÃO FOR

PRA QUE SERVE ESSE ARQUIVO

MUITO OBRIGADOOO

#12

AH O MEU Fornecedor.hbm.xml fica com aquele exclamação (aviso)

a seguinte mensagem “No grammar constraints (DTD or XML schema) detected for the document.”

e tbm

esses que está sublinhado fica riscado no eclipse , tipo um erro de portugues do word

#13

Parece estar tudo certo, apesar da mensagem informando que ele não encontrou o Fornecedor.hbm.xml na pasta Negocio, você já verificou se ele está lá? Se estiver, tente usar o arquivo hibernate.cfg.xml que fiz abaixo, colocando ele na sua pasta src.

Ele substitui o hibernate properties, mas nele eu informei a localização do seu arquivo Fornecedor.hbm.xml.
É por isso que eu prefiro annotations, às vezes um problema nos xml é difícil de descobrir, no site do hibernate você pode baixa o hibernate tools e pedir para ele criar seu arquivo .hbm.xml, pode ser um problema nesse arquivo.
