#1

Pessoal estou com o seguinte erro:

java.lang.NoClassDefFoundError: br/com/xxx/ep/afac/modelo/dao/PontoDAO (wrong name: br/com/petrobras/ep/afac/modelo/dao/PontoDao)

Não entendo pois o nome está correto em todos os lugares… segue os arquivos:

	}

	public void setPontosSelDao(PontosSelecionadosDAO pontosSelDao) {

PontoDAO:

package br.com.xxx.ep.afac.modelo.dao;

import br.com.xxx.ep.afac.modelo.entity.Ponto;

public interface PontoDAO {
	
	public List<Ponto> obterPontos(List<String> listaCodigos);
	
	public List<Ponto> obterTodos();
}

Alguem faz ideia ??

Parece que está procurando por PontoDao e a classe é com maiuscula PontoDAO… Porém já dei um find no projeto e não existe nenhuma referencia assim minuscula

#4

Onde você está mapeando o “sistemaDAO”?

#5

como assim mapeando?

OBS: é PontoDAO… SistemaDAO também está dando o mesmo erro, porém eu removi do exemplo ali pra simplificar.

#6

Existe essa classe: br.com.xxx.ep.afac.modelo.dao.SistemaDAO ?

#7

existe, com certeza rs

#8

O Spring não conhece essa classe. Ele não sabe onde ela está. Ele não vai procurar item a item dentro da estrutura que você possui para localizá-lo.
O application context precisa dizer a ele quem é quem e onde está (eventualmente essa configuração pode ser personalizada, mas isto é outra história).

#9

Pelo que eu entendi no log, o erro acontece quando vai carregar a classe br.com.xxx.ep.afac.modelo.dao.jdbc.PontoJdbcDAO, diz que essa classe não enxerga uma implementação da interface classe br.com.xxx.ep.afac.modelo.dao.PontoDAO. Existe alguma classe que implementa PontoDAO? O erro pode ser esse, tentativa de instanciar uma interface. Posta a classe PontoJdbcDAO.

Faça do seu PontoDAO uma classe.

#12

foi mal, postei sem o public class PontoJdbcDAO implements PontoDAO{

ou seja, é uma interface msm

#13

Porque você não coloca os métodos de PontoDAO dentro de PontoJdbcDAO?

#14

a interface ajuda na manutenção do código, mas eu removi ela fazer oq… então o problema acabou rsrs

mas valeu ae galera

#15

Então, acho que você estava indo na contramão. A idéia é criar uma interface abragente, como:

public interface GenericDAO<T, ID extends Serializable> {
 
    T findById(ID id, boolean lock);
 
    List<T> findAll();
 
    List<T> findByExample(T exampleInstance);
 
    T makePersistent(T entity);
 
    void makeTransient(T entity);
}

E depois a classe implementadora como:

public abstract class GenericHibernateDAO<T, ID extends Serializable>
        implements GenericDAO<T, ID> {
 
    private Class<T> persistentClass;
    private Session session;
 
    public GenericHibernateDAO() {
        this.persistentClass = (Class<T>) ((ParameterizedType) getClass()
                                .getGenericSuperclass()).getActualTypeArguments()[0];
     }
 
    @SuppressWarnings("unchecked")
    public void setSession(Session s) {
        this.session = s;
    }
 
    protected Session getSession() {
        if (session == null)
            throw new IllegalStateException("Session has not been set on DAO before usage");
        return session;
    }
 
    public Class<T> getPersistentClass() {
        return persistentClass;
    }
 
    @SuppressWarnings("unchecked")
    public T findById(ID id, boolean lock) {
        T entity;
        if (lock)
            entity = (T) getSession().load(getPersistentClass(), id, LockMode.UPGRADE);
        else
            entity = (T) getSession().load(getPersistentClass(), id);
 
        return entity;
    }
 
    @SuppressWarnings("unchecked")
    public List<T> findAll() {
        return findByCriteria();
    }
 
    @SuppressWarnings("unchecked")
    public List<T> findByExample(T exampleInstance, String[] excludeProperty) {
        Criteria crit = getSession().createCriteria(getPersistentClass());
        Example example =  Example.create(exampleInstance);
        for (String exclude : excludeProperty) {
            example.excludeProperty(exclude);
        }
        crit.add(example);
        return crit.list();
    }
 
    @SuppressWarnings("unchecked")
    public T makePersistent(T entity) {
        getSession().saveOrUpdate(entity);
        return entity;
    }
 
    public void makeTransient(T entity) {
        getSession().delete(entity);
    }
 
    public void flush() {
        getSession().flush();
    }
 
    public void clear() {
        getSession().clear();
    }
 
    /**
     * Use this inside subclasses as a convenience method.
     */
    @SuppressWarnings("unchecked")
    protected List<T> findByCriteria(Criterion... criterion) {
        Criteria crit = getSession().createCriteria(getPersistentClass());
        for (Criterion c : criterion) {
            crit.add(c);
        }
        return crit.list();
   }
 
}

Caso precise de métodos específicos crie uma classe DAO específica estendendo GenericDAO.

*Neste caso usando Hibernate. Fonte:http://community.jboss.org/wiki/GenericDataAccessObjects#The_DAO_interfaces

Dica modesta: Comece a usar Spring + Hibernate.
