Galera estou tentando criar um DAO Generico com o Spring 3 e hibernate, mas sem sucesso.
Gostaria da ajuda de vcs, alguem tem um exemplo de como criar um dao generico com Spring e hibernate?
Obrigado!
Nesse post: http://www.guj.com.br/java/234011-forma-certa-de-construir-o-dao tem um exemplo de DAO Genérico que criei integrando Spring e Hibernate.
Valeu cara pela sua ajuda, tentei utilizar o seu exemplo na classe abaixo, mas ao rodar o projeto o erro abaixo é exibido.
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
public class BaseDAO<T> extends HibernateDaoSupport {
public BaseDAO() {
}
public void salvar(T obj) {
getHibernateTemplate().saveOrUpdate(obj);
getHibernateTemplate().flush();
}
public void remover(Object obj) {
getHibernateTemplate().delete(obj);
getHibernateTemplate().flush();
}
@SuppressWarnings("unchecked")
public T buscar(Class<T> clazz, Long id) {
return (T) getHibernateTemplate().get(clazz, id);
}
@SuppressWarnings("unchecked")
public List<T> listar(Class<T> clazz) {
return (List<T>) getHibernateTemplate().find("from " + clazz.getName());
}

Testa aí e manda o feedback!
Valeu pela ajuda Emmanuel, cara as suas configurações deram certo aqui, tenho mais algumas duvidas.
Ao criar um novo DAO e extender do GenericDao que crie, terei que adicionar este novo DAO no xml de configuração injetando o sessionfactory?
Exemplo
<bean id="NovoDAO" class="br.com.mka.dao.NovoDAO">
<!-- Injeta o hibernateTemplate na classe DAO -->
<property name="sessionFactory" ref="sessionFactory" />
</bean>Pois aqui exigiu que eu coloca-se todos os daos novos no xml, tem alguma maneira de não precisar?
Outra duvida, depois de criar meus daos e extender eles do GenericDao, ao tentar utiliza-los em uma classe passando eles pelo construtor como a classe abaixo.
@ManagedBean
public class ImportarControle {
private BaseGFKDAO baseGfkDao;
private BaseScanDAO baseScanDao;
private VolumeMercadoDAO volDao;
// @Autowired
// public ImportarControle() {
// }
@Autowired
public ImportarControle(BaseGFKDAO baseGfkDao, BaseScanDAO baseScanDao, VolumeMercadoDAO volDao) {
this.baseGfkDao = baseGfkDao;
this.baseScanDao = baseScanDao;
this.volDao = volDao;
}O seguinte erro é gerado, sabe me dizer o que estou fazendo de errado?

at org.apache.el.parser.AstValue.invoke(AstValue.java:187)Quando eu uso Anotação do Spring eu não configuro nada no xml do spring, pois ele auto detecta.
Eu tive um problema com o Spring que ele não conseguia injetar as classes pelo construtor ai eu criei getrs and setrs e um construtor vazio, e adicionei a anotação @Autowired no atributo e não mais no construtor e tudo funcionou, n sei c é o seu caso, mais antes crie um construtor vazio(sem parâmetros) para todas as suas classes que o spring estiver gerenciando,
Já que vc esta preocurando sobre o dao generico com hibernate dá uma olhada neste link abaixo sobre como utilizar um filtro generico com o hibernate, para min é muito util pode ser para vc tb… http://www.guj.com.br/java/221618-filter-dinamico-para-hibernate
Eu tentei colocar Anotation mas parece que ele não pega, pois se eu tirar os daos do xml dá erro
Classe Dao estendendo da Genérica.

}
}é que para ativar o 'auto detecta precisa configurar no xml do spring(spring-configured, component-scan … ), eu recomendo depois vc estudar pois evita de ficar escrevendo muitas linhas no arquivo xml do spring
Bom para ñ, sair muito da sua duvida principal mantenha as linhas do seu xml, como tava e tenta apenas trocar a anotação @Autowired para o field e não mais no contrutor e depois cria o construtor vazio da classe br.com.mka.web.controle.ImportarControle… era ai que tava dando erro!
Cara fiz da forma que vc disse, tirei o construtor, não deu mais o erro, mas os daos estão null, ou seja não foram carregados.
Na linha 99 faço o teste para ver se ele foi carregado mas sem sucesso, está null e nenhuma exceção foi gerada!

Ué Cacilda, claro que os DAOs vão estar nulos, você não injetou a instancia do DAO genérico nas propriedades da classe ImportarControle. Faz um casting e injeta. Lembre-se o cérebro do Spring está no xml, o que você descrever lá ele vai fazer.
Acho que não estou conseguindo injetar pois meu spring não está reconhecendo anotation, ai teria que fazer via xml a injeção, segue abaixo o meu spring.xml onde está toda a configuração do projeto, não sei o que pode estar errado pois configurei tudo que estou utilizando nele.

Os meus Daos já estende do DAO generico, não entendi o que tenho que fazer para funcionar, os daos estão na classe e todos estão marcados com autowire, o que mais tenho que fazer para ir?
Acima enviei meu spring.xml
Cara colocando na mão vai, os daos foram carregados, mas soh se eu colocar na mão, não se porque ele não ta pegando as annotations.
Segue o xml as linhas 75 a 79 injetam os daos.

<context:component-scan base-package="br.com.meu.pacote.para.o.spring.scanear.view" />
<context:annotation-config />
<context:spring-configured/>Outra coisa eu adiciono o @Autowide no atributo e não no método, mais achu q o spring é suficientemente inteligente e deve enteder. Para usar anotação vc tem que configurar o spring pois no padrão dele as anotações vem desativadas…
Consegui fazer funcionar com annotation, mas eu fiz o inverso que vc eu coloquei @Autowire apenas nos sets e não nos atributos e foi de boa, agora os daos eu tive que deixar no xml, por annotation não foi, unico que eu consegui configurar por annotation foi o controler.
Nas suas classes daos vc precisa colocar a anotação @Repository do Spring para ele saber que deve gerenciar tal classe dai vc pode remover do xml…
Talvez vc tb precise configurar tb quais pacotes o spring deve scanear… é o seguinte comando:
<context:component-scan base-package="br.com.meu.pacote.para.o.spring.scanear.dao" />
