[Ajuda] - VRaptor 3 + Hibernate + Integração com Spring + GenericDAO

tá vendo pq não pode colocar transaction no dao? :stuck_out_tongue:
vou te explicar o que acontece:

 @Path("/")    
     public void index() {  
   
         Assinante assinante = this.assinanteDao.get(new Long("5"));   // abre uma sessão pra poder consultar no banco
        //o assinante está preso à essa sessão
       
         assinante.setApelido("CAELUM");  
         assinanteDao.update(assinante); // por causa do @Transactional, ele abre outra sessão pra poder atualizar o assinante...
         // mas como o assinante está preso à primeira sessão dá aquele erro...
           
         result.include("variable", "VRaptor!");       
         result.include("assinante", assinante);  
     }

tenta colocar @Transactional no método index… ou dar um evict no assinante após o get… pode ser que o Transactional não funcione num controller…

#22

Então…

Isso aqui tá a maior torre de palitinhos rsrs cada hora q eu tiro um cai uma bolinha rs
Então… esse erro de 2 sessões abertas to crente que é problema do Spring, pois resolvi tirar a transação e salvar direto, e deu o mesmo erro…
Estou baixando a versão 2.5 do Spring…

“Atualizando…”

Acabei de baixar a versão 2.5, mudei todos os jars do spring, deixei tudo igual ao material da apostila, mesmo assim não funcionou… quando tem @Transactional

“Initialization of bean failed; nested exception is org.springframework.aop.framework.AopConfigException: Could not generate CGLIB subclass of class [class br.eventos.controller.IndexController]: Common causes of this problem include using a final class or a non-visible class; nested exception is java.lang.IllegalArgumentException: Superclass has no null constructors but no arguments were given
”

Quando sem, dá o erro de 2 sessions

buaa…rs

Estou achando que o problema é que tá abrindo 2 sessions no SessionFactoryUtils.doGetSession

#23

o jeito “facil” de resolver isso é tirando o SessionCreator e fazendo todos os seus daos estenderem o HibernateDaoSupport do Spring… como seus daos estendem o GenericDao isso fica fácil…

o chato disso é que vc fica preso ao spring… precisa ver como fazer pros Controllers aceitarem o @Transactional… vou ver se consigo por aqui…

#24

consegui fazer funcionar o @Transactional no Controller…

O Spring é burro e não sabe criar proxies se a classe tiver construtor com argumentos… pra fazer o Transactional ele cria proxies da sua classe…

então, para tudo funcionar direitinho, vc precisa usar injeção via setter… ou seja, crie um setter pra cada coisa que vc está recebendo no construtor, anote com @Autowired do spring, remova o construtor ou adicione um construtor sem argumentos…

me diga se funcionou plz =)

#25

hehehehe
hey mestre apelo agora kkkk
boiei rsrs dá uns minutinhos vou ver se eu entendi tudo que tu falou rsrs
e executar aqui

pq logo de cara eu já tive duvidas, tirar os parametros de qual constructor ? da CriadorDeSessao, ou da DAO rs

#26

os parâmetros do construtor do controller

#27

Já ranquei da criador de sessão rsrs, estudinho rapido @Autowired marca a variavel que é para injetar certo ?
na

SessionCreator fiz o seguinte

@Autowired
private SessionFactory factory;
@Autowired
private Proxifier proxifier;

mudei o constructor para public SessionCreator()

depois fui na GenericDAO coloquei na @Autowired na
private Session session

e tirei o construtor da AssinanteDAO(Session session) e mudei para AssinanteDAO()

desse jeito funcionou com o erro das 2 sessions rs

agora que li aqui vou colocar na Controller

#28

não precisa mexer nos construtores dos daos e sessionFactory… só no controller

#29

Ahhhh ok…

Vou voltar o constructor da SessionCreator então, e da DAO também…

Agora eu consegui um progresso… o erro da dupla sessão acabou quando eu joguei o @Transactional na action da controller, mas ai pelo visto ele fechou a session antes de terminar de renderizar a view olha o erro novo

#30

ele fecha a sessão qdo acaba a transação… é assim q o spring trabalha…

no caso ele fecha a sessão qdo acaba o método do controller…

tenta registrar o filtro OpenSessionInViewFilter no web.xml, depois do filtro do vraptor…

org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

#31

assim né ??

vraptor br.com.caelum.vraptor.VRaptor openSessionInViewFilter org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

Atualizano…
Então acabei de ver que tem de fazer o filter mapping, bom, com o filter-mapping só a consulta deu certo…
Agora quando coloca a @Transaction, volta o erro do lazy-loading, e sem @Transaction 2 session aberta…

Se for assim não deu certo também, rs mas ai agora to tentando fazer isso funcionar meio que por questão de honra… mas já estou me perguntando, este é o melhor meio mesmo???
Será que fazer o controle das transações na unha lá na dao dando o beginTransaction e tal não é melhor ou a mesma coisa sem esse trabalhão todo rs
Pq não sei se é por que sou novatão, mas que trabalho para funcionar isso hien… rs

Vi um cookbook do VRaptor que o Tomaz fez q ele faz um interceptor pra criar a notation @Transaction e poupar codigo, que tu acha disso ?

Valeu mestre! Enquanto isso to aqui junto no google rs

#32

o melhor jeito de fazer tudo funcionar 100% com o Transactional do Spring é usando o hibernate do jeito dele: estendendo o HibernateDaoSupport nos DAOs e fazendo as operações usando o HibernateTemplate…

se vc quer um controle simples de transação (abrir no começo e fechar ao final de qqer requisição), vc pode usar o do próprio vraptor… pra isso basta registrar o HibernateCustomProvider http://vraptor.caelum.com.br/documentacao/componentes-utilitarios-opcionais/

se vc quiser economizar transações, não abrindo e fechando elas pra consultas, vc pode fazer o Transactional do Lavieri… é bem simples de fazer, e é só anotar os controllers,

se vc quiser coisas complicadas, como propagation, nested transactions e coisa e tal, é melhor usar o Transaction do Spring, mas como eu disse, vc tem que usar o hibernate do jeito dele…

o que vc prefere fazer?

#33

acredito que para este sistema que tenho de fazer (que é trabalho da pós), já basta economizar as transações
mas agora tbm fiquei puto da vida com esse Spring rsrs quero q quero fazer essa criança rodar… rs
Amanha vou ver se consigo me organizar e vou subir um novo projeto, e fazer do modo do Lavieri… rodando tudo certinho eu volto para o modo Spring, rs pq a tenho de ter apresentar pelo menos uma tela para sexta feira rsrs

valeu mesmo, prox vez q eu estiver ai em SP te pago uma rodada no buteko mais prox!!! rs

por hoje acho que é só…
fiquei parado no erro do Lazy, mesmo com o OpenSessionView, eu tava lendo, não tem de declarar um bean no applicationContext não ??

boa noite :wink:

#34

Hey Lucas…

Fiz umas mudanças aqui, peguei o SessionCreator que o Lavieri postou em um cookbook, com ele funcionou a notação @Transaction na controller, mas acho que não funcionou do modo correto não, pois eu criei 2 objetos que tem relacionamento, e mandei dar persist em um deles, deu erro no outro e mesmo assim criou o primeiro (os objetos são Assinante e Endereco, ele criou o Assinante, mas deu erro no Endereco por que eu não atribui um campo necessário para provocar o erro)
O correto era não criar nem Endereço e nem Assinante dar o rollback né ?

Agora to cabrero, queria esse controle de @Transaction na controller, do modo que tu falou fiquei com agua na boca rsrs

Para o pessoal da comunidade, ninguem tem um exemplo desse por ai não rsrs

Valeu!!

#36

O SessionCreator do Laviery só cria sessões, não controla as transações…

se vc tá usando o @Transactional do Spring, vc PRECISA usar as sessões do Spring… no caso daquele sessionCreator, ele tá criando novas sessões…

Se vc quiser usar @Transactional nos controllers (só vai funcionar nos controllers, mas vc pode anotar tanto metodos qto classes) vc pode fazer o seguinte:

  • Tire a configuração de transações do applicationContext.xml… talvez até apagar esse arquivo

  • crie o Interceptor:

@Intercepts
public class TransactionInterceptor implements Interceptor { // Interceptor do vraptor

   private final Session session;

   public TransactionInterceptor(Session session) {
        this.session = session
   }
   public boolean accepts(ResourceMethod method) {
        return method.containsAnnotation(Transactional.class); // pode ser a do Spring, ou vc pode criar uma própria da sua app
   }

   public void intercept(InterceptorStack stack, ResourceMethod method, Object instance) {
        Transaction tx = session.beginTransaction();

        try {
              stack.next(method, instance);
              tx.commit();
        } catch (Exception e) {
              if (tx.isActive()) {
                  tx.rollback();
              }
              throw new InterceptionException(e);
        }
   }
}
#37

Hey…

Vou tentar essa… vlw…
Só uma duvida…
no arquivo http://code.google.com/p/eventos-ufscar/source/browse/webEventos_v3/src/br/eventos/library/hibernate/AbstractSessionCreator.java
nas linhas 38 ~ 40, eu mudei do arquivo do Lavieri, coloquei igual à apostila, e mudei de hibernate.classic.Session, para apenas hibernate.session…
Funcionou update e consulta sem add nada a mais, mas na hora de ver se o @Transaction estava funcionando descobri que não… mas na teoria era né ?

#38

na teoria não era pra funcionar… a versão da apostila já é lazy…

o problema é outro…

tire o applicationContext.xml, crie a CriadorDeSession e CriadorDeSessionFactory como está na apostila e faça o interceptor que eu te mandei na outra mensagem, deve funcionar

#39

blz… rsrs eu tava lhe respondendo agora…

do jeito que está a classe SessionCreator, eu tirei o applicationContext.xml, e implementei a classe que voce passou… deu o erro que postei agora…
To mudando a SessionCreator para igual da apostila rsrs
