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

### set log levels - for more verbose logging change 'info' to 'debug' ###

hibernate.properties

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

Fornecedor.hbm.xml

<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

erickfm8 15 de mar. de 2010

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?

mrrbigu 16 de mar. de 2010

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:

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;
	}
}

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

Seria bem legal ^^

erickfm8 16 de mar. de 2010

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

package Persistencia;

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

meu mapeamento Fornecedor.hbm.xml

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

eu axo que o erro esta nesse mapeamento

Por favor pessoal me ajude

Obrigado

mrrbigu 16 de mar. de 2010

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.

erickfm8 16 de mar. de 2010

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

mrrbigu 16 de mar. de 2010

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.

erickfm8 16 de mar. de 2010

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();
	}
}

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.

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

Então está sim dentro do pacote Negocio, ah colequei o arquivo que vc me pediu.

Uma pergunta este arquivo substitui qual?
o hiberante.properties?

finalizando adicionando o arquivo continua dando o mesmo erro

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.
