Bom dia pessoal, estou estudando um pouco vraptor e já me deparei com um probleminha. Estou seguindo a apostila da caelum FJ-28, gostaria que pudessem me dar uma mão, ao tentar acessar minha lista de produtos cadastrados, é levantado este erro no console:

segue abaixo minhas classes DAO e controller:

@Resource
public class ProdutosController {

	private ProdutoDAO dao;
	private Result result;
	
	public ProdutosController(ProdutoDAO dao, Result result) {
		this.dao = dao;
		this.result = result;
	}

	/*Utilizado para recuperar uma lista de objetos produto
	 * @param
	 */	
	public List<Produto> lista() {
		return dao.listaTudo();
	}

@Component
public class ProdutoDAO {
	
	private Session session;
	
	// Utilizado para criação da sessão.
	public ProdutoDAO(){
		SessionFactory factory = new CriadorDeSessionFactory().getInstance();
		this.session = new CriadorDeSession(factory).getInstance();
	}
                public List<Produto> listaTudo(){
		List<Produto> lista = this.session.createCriteria(Produto.class).list(); 
		return lista;
	}
}

Estes problemas começaram a aparecer depois que coloquei as anotattions na classe CriadorDeSessionFactory:

@Component
@ApplicationScoped
public class CriadorDeSessionFactory implements ComponentFactory<SessionFactory>{
	
	private SessionFactory factory;
	
	@PostConstruct
	public void abre(){
		AnnotationConfiguration configuration = new AnnotationConfiguration();
		configuration.configure();
		this.factory = configuration.buildSessionFactory();
		System.out.println("foi aberta a fabrica de sessoes");
	}
	
	public SessionFactory getInstance() {
		return this.factory;
	}
	
	@PreDestroy
	public void fecha(){
		this.factory.close();
		System.out.println("foi aberta a fabrica de sessoes");
	}
	
	
}

O seu ProdutoDAO está nulo, por algum motivo o VRaptor3 não está injetando ele no controller (provavelmente por causa do CriadorDeSessionFactory). Eu sugiro você utilizar o VRaptor3 para injetar o SessionFactory, ao invés de fazer manualmente.

Lucas, estou com o mesmo problema do KamuiEx , mas ali na Controller já não está da forma correta? Como ficaria a injeção de depência do “CriadorDeSession” ?

K
KamuiEx

Pelo modelo que eu estou seguindo na apostila da caelum, ela passa pra ser feita esta injeção da DAO no controller, desta forma. Antes de colocar estas anotattion para definir o ciclo de vida da criação da session, não havia este problema, agora, depois que eu coloquei desta forma pra entender melhor o que a apostila tah passando, tah dando este problema, num estou conseguindo entender esse problema, pq naum estou nem conseguindo debugar pra entender melhor…
Obrigado pela ajuda.

Cristiano, não é injetar o CriadorDeSessionFactory. No caso, esse CriadorDeSessionFactory não iria existir e o que seria injetado era a SessionFactory do Hibernate. Se não me engano, no site do VRaptor3 tem falando sobre isso.

Lucas_Cavalcanti
Lucas_Cavalcanti

no ProdutoDao, vc deveria receber a Session no construtor…

o CriadorDeSession e o CriadorDeSessionFactory são ComponentFactory’s, ou seja, o VRaptor vai usá-los sempre que precisar injetar em alguém Session ou SessionFactory

K
KamuiEx

Como eu poderia alterar meu código, para que eu ja recebesse esta session criada no meu construtor. No codigo atual, esta session esta sendo criada dentro do contrutor, ela não esta sendo injetada, me corrija se estiver certo, comparei o código com o da apostila e esta igual, só se a caelum passou um código errado. Obrigado.

Lucas_Cavalcanti
Lucas_Cavalcanti

a idéia da apostila é evoluir o código pra vc tirar a criação da sessão de dentro do construtor…

o construtor do produtoDao deveria ser:

public ProdutoDao(Session session) {
    this.session = session;
}

Muito interessante, valeu pela dica e vou tentar implementar, se der certo posto o resultado :slight_smile:

o construtor do produtoDao deveria ser:

public ProdutoDao(Session session) { this.session = session; }


Na action da DAO então eu faria algo como:

public void salvar(Cliente cliente){ Session session = session.getInstance() //aqui não me lembro se foi assim que fiz, mas é allgo parecido com isso Transaction tx = beginTransactio(); session.save(cliente); tx.commit(); }
Ou bastaria passar o session somente no construtor da classe e nada mais? Onde a DAO ficaria somente assim:

public void salvar(Cliente cliente){ Transaction tx = beginTransactio(); session.save(cliente); tx.commit(); }

Lucas_Cavalcanti
Lucas_Cavalcanti

basta passar somente a session

Vou testar sua dica também, e a do seu chará também, obrigado :smiley:

Se estou entendendo bem, qnd eu chamo minha classe DAO, eu tenho que passar uma session então no construtor dela, assim, estou meio novo nessa pratica, mais tah fugindo um pouco da ideia do que está sendo passada de lógica no curso do vraptor, pq de acordo com o código, dentro da classe controller eu vou ter que gerar uma instancia de uma session para passar pra minha DAO, a idéia que foi passada na apostila de treinamento era justamente o inverso. Me corrija se estiver errado. Pessoal obrigado pela atenção…

Lucas_Cavalcanti
Lucas_Cavalcanti

a idéia é que vc vai receber, também, o ProdutoDao no construtor do ProdutoController… assim o VRaptor se preocupa em instanciar o ProdutoDao.

ou seja, não vai ser vc que vai ter que gerar uma instância da session, vai ser o VRaptor

C
cristianogro

Seguindo o tutorial do Tomaz Lavieri como ficaria minha DAO, eu teria que fazer algo para abrir a conexão com o banco de dados ou como seria?

Lucas_Cavalcanti
Lucas_Cavalcanti

a Session do hibernate já abre conexão com o BD…

vc pode receber a session no construtor do ProdutoDao:

public ProdutoDao(Session session) {
    this.session = session;
}

dê uma olhada na apostila do vraptor:

Dúvida: Estou seguindo essas dicas http://vraptor.caelum.com.br/cookbook/interceptando-recursos-anotados/ e não vi usar a tag @Transactional nos métodos que são de pesquisa, só vi usando nos métodos de insert e update, no caso dos métodos de consulta a sessão também será fechada ou vai continuar aberta?

Lucas_Cavalcanti
Lucas_Cavalcanti

o transactional é só pra transações… as sessões são abertas (e fechadas) toda a requisição

C
cristianogro

Ok, agora entendi, então lá no construtor do meu Controller como tenho meu DAO declarado, quando eu fazer uma requisição de consulta por exemplo ele vai abrir a conexão, processar a requisição, fechar a conexão e devolver o resultado pro controller e certo?

Lucas_Cavalcanti
Lucas_Cavalcanti

mais ou menos…
a ordem é essa:

começa a requisição
abre a sessão
começa uma transação (se anotado)

executa o controller (e consultas ou alterações no banco)

comita a transação (se anotado)
fecha a sessão
termina a requisição

C
cristianogro

Lucas acho que estou fazendo errado mas vamos lá, minhas classes estão assim:

AbreSession: 
@Component
public class AbreSession implements ComponentFactory<Session> {
    private SessionFactory factory;

    public AbreSession(SessionFactory factory) {
        this.factory = factory;
    }

    public Session getInstance() {
        Session session = factory.openSession();
        return session;
    }
}
AbreSessionFactory: 
@Component
public class AbreSessionFactory implements ComponentFactory<SessionFactory> {

    public SessionFactory getInstance() {
        AnnotationConfiguration configuration = new AnnotationConfiguration();
        configuration.configure();
        SessionFactory factory = configuration.buildSessionFactory();
        return factory;
    }
}

        //private final Session session;
       //Na dica que estou seguindo a linha acima estava descomentada mas a IDE acusava que a variável não tava inicializada, daí criei as duas linhas abaixo
       //As duas linhas abaixo não sei se precisam mas tive que colocá-las pra conseguir rodar o projeto
        SessionFactory factory = new AbreSessionFactory().getInstance();
        Session session = new AbreSession(factory).getInstance();
        public HibernateTransactionInterceptor(Session session) {
            this.session = session;
        }
        
        public void intercept(InterceptorStack stack, ResourceMethod method,
                                Object instance) {

                transaction = session.beginTransaction();
                stack.next(method, instance);
                transaction.commit();
            } finally {
                System.out.println("Inteceptou");
                if (transaction.isActive()) {
                    transaction.rollback();
                }
            }
        }

            return  method
                .getMethod() //metodo anotado
                .isAnnotationPresent(Transactional.class)
            || method
                .getResource() //ou recurso anotado
                .getType()

Veja como o número de conexões aumentou: [url]http://img707.imageshack.us/img707/5417/msql2.jpg[/url] Observe na minha classe ClienteController no construtor dela a quantidade de DAO's que recebo, cada DAO que está no construtor ele abre uma nova conexão a qual nunca é fechada. Como eu poderia contornar isso? Até o momento a classe TransactionInterceptor não fecha conexão em momento algum, eu não teria que em algum ponto dela mandar fechar conexão e daí na minha DAO nos trechos onde são executados as consultas eu anotar com @Transactional??

as sessions não vão se fechar sozinhas, o VRaptor não faz isso por vc automaticamente… achei que vc estava usando o componente do VRaptor pra isso
(http://vraptor.caelum.com.br/documentacao/componentes-utilitarios-opcionais/)

as suas classes AbreSession e AbreSessionFactory deveriam ser iguais às SessionCreator e SessionFactoryCreator desse pacote:
https://github.com/caelum/vraptor/tree/master/vraptor-core/src/main/java/br/com/caelum/vraptor/util/hibernate

assim as sessões serão fechadas no final da requisição

Não conhecia os componentes adicionais do V-Raptor, value pela dica :). Usando este componente as chamadas na minha DAO ficariam de forma similar ao que tenho hoje correto?

Lucas_Cavalcanti

sim, só receber session no construtor

Bom tô tentando implementar, mas ao acessar a minha página principal ocorre o seguinte erro:

br.bmweb.util.AbreSession]: Constructor threw exception; nested exception is java.lang.RuntimeException: Uncompilable source code - variable factory might not have been initialized

tá dando um erro de compilação estranho…

se vc vai usar essas classes do jeito que elas estão, é melhor usar as já prontas do VRaptor

tire todas as anotações @Component das AbreXXX e do interceptor, e não use o seu HibernateCustomProvider…

ao invés disso coloque no seu web.xml:

<context-param>
		<param-name>br.com.caelum.vraptor.packages</param-name>
		<param-value>br.com.caelum.vraptor.util.hibernate</param-value>
	</context-param>

e tire a configuração de provider se vc tiver alguma

Removi tudo relacionado ao custom provider, e tirei todas as anotações @Component das AbreXXX e do interceptor e alterei o web.xml e ocorreu o erro:

Pelo erro: 
org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.Session] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}
Este erro ele não tá implicando com o meu import da classe? A URL que chamo é essa: [url]http://localhost:8080/BMWEB/cliente/index2[/url] Onde o controller tá assim: 
package br.bmweb.controller;

        this.session = session;
    }

    public void index2() {

O trecho inicial da ClienteDao tá assim: 
package br.bmweb.dao;

    //Session session = new AbreSession(factory).getInstance();
    Session session;
    public ClienteDao(Session session){
        this.session = session;

    }
Tá faltando algo? Preciso ter um applicationContext.xml ??

Esqueci de colocar mas aí vão as classes de conexão:

As notações delas estão corretas?

Lucas_Cavalcanti

as classes estão corretas, aparentemente…

copia exatamente isso pro seu web.xml:

<context-param>
		<param-name>br.com.caelum.vraptor.packages</param-name>
		<param-value>br.com.caelum.vraptor.util.hibernate</param-value>
	</context-param>

e tire a configuração de packages anterior
