Pessoal,
Em primeiro lugar desculpem o off-topic, mas sei que alguns colegas daqui
usam o Spring
no backend java como eu...
Baixei a última versão do blazeds e criei um projeto teste com o
blazeds-spring.war.
Tudo beleza, mas estou tendo um problema na injeção de dependência com o
Spring.
Segue as minhas classes
public interface IUsuarioDAO {
public void save();
}
@Repository(value = "usuarioDAO")
@Transactional(propagation=Propagation.REQUIRED,
rollbackFor=Exception.class)
public class UsuarioDAO implements IUsuarioDAO {
@Override
public void save() {
// TODO Auto-generated method stub
}
}
public interface IUsuarioUseCase {
public void salva(Usuario usuario);
}
@Service(value = "usuarioUseCase")
@RemotingDestination
public class UsuarioUseCase implements IUsuarioUseCase {
protected UsuarioDAO dao;
@Autowired
@RemotingExclude
public void setDao(UsuarioDAO dao) {
this.dao = dao;
}
@Override
public void salva(Usuario usuario) {
dao.save();
System.out.println("salva...");
}
}
Rodo a aplicação e recebo o seguinte erro:
SEVERE: Exception sending context initialized event to listener instance of
class org.springframework.web.context.ContextLoaderListener

Alguém sabe o porque que isso ocorre?
Tenho uma arquitetura semelhante no spring 2.5 e esse problema não ocorre.
Abaixo trecho do appConfig.xml

Ao que parece ele diz que o bean usuarioDAO não é único (mas é)...
Já tentei usar @Qualifier e nada..
Se alguém souber de algo que possa resolver fico agradecido
