OpenSessionInViewFilter + ViewScope

ArturSampaio · Abril 27, 2012, 6:30am

Tenho uma aplicação construída com JSF2 + Primefaces + Spring 3 + Hibernate 4. os backingbeans usam ViewScope.
Implementei o OpenSessionInView e vejo nos LOG´s que ele parece estar funcionando corretamente.
Mas tenho uma dataTable na camada de apresentação, que sob clique do usuário exibe informações adicionais sobre a entidade selecionada - navegando em seus relacionamentos. Nesse momento eu estou recebendo a exceção:

Alguma idéia sobre o que pode estar acontecendo? Minha suspeita é de que o problema é com o ViewScope.

Obs: eu estava usando JPA, com OpenEntityManagerInViewFilter, e tudo funcionava bem. Mas decidimos migrar pra Hibernate puro…

Obrigado

Altere o escopo do seu Bean para Session e teste, se ocorrer o mesmo erro, o problema não é o escopo.

Olha, cara, esse não é o primeiro tópico que eu vejo ser aberto que comenta sobre comportamentos “estranhos” em lugares onde o Hibernate 4 está sendo usado.

No projeto que eu estou agora nós tentamos migrar do Hibernate 3 para o 4 e ocorreu um problema que depois de pesquisar eu descobri que era um bug do Hibernate que só seria corrigido no lançamento do Hibernate 5.

Não estou dizendo que esse é o problema, mas eu particularmente não recomendo o uso do Hibernate 4.

Hericksnake · Abril 27, 2012, 8:21am

Mesmo problema aqui.
Só que ao invés de DataTable o erro ocorre nos combobox.

ArturSampaio · Abril 27, 2012, 8:29am

só pra testar, eu mudei pra Session. mas o problema continua.
mas minha desconfiança quanto ao escopo é justamente o oposto: estive supondo que o OSIV só atendesse RequestScope.
Já a suspeita sobre o Hibernate4 é bastante válida.

Fora isso, li em algum lugar que pra usar OSIV é necessário que todo acesso ao banco seja feito dentro de uma transação. Então adicionei no applicationContext

    <bean id="sgpcTransactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sgpcSessionFactory"/>
    </bean>
    <tx:annotation-driven transaction-manager="sgpcTransactionManager"/>

e em todos os métodos de DAO (inclusive os que só fazem consulta)

@Transactional(readOnly = true)

(claro que nos de insert, update e delete eu coloquei o “readOnly=false”)

é só isso que é necessário mesmo? como eu posso ter ctz q está funcionando?

O que me parece é que o OSIV funciona direito, mas os lazyloading usam uma sessão diferente daquela do OSIV.

meus métodos de DAO são parecidos com:

@Transactional(readOnly = true)
    public List<ObjetoProtegidoBean> pesquisar() {
        List<ObjetoProtegidoBean> objetosProtegidos = null;
        Session sess = getSessionFactory().getCurrentSession();
        try {
            Query q = sess.getNamedQuery("ObjetoProtegidoBean.findAll");
            objetosProtegidos = q.list();
        } catch (Exception e) {
            logger.debug(e);
        }
        return objetosProtegidos;
    }

alguns métodos usam criteria, mas o acesso à sessão é idêntico. falta algo? preciso explicitar o uso da transação?

Obrigado,

Tenho a impressão de que a JBoss se precipitou ao disponibilizar o Hibernate 4.
Não apenas tópicos que apresentam problemas com integração, mas muitos em que esta versão é utilizada apresentam problemas.

Sinceramente eu concordo.

Depois que vi uma exceção que dizia: [quote]ERROR hibernate.AssertionFailure - an assertion failure occured (this may indicate a bug in Hibernate…[/quote]
decidi que não tentaria mais nada com o Hibernate 4

ArturSampaio · Abril 27, 2012, 8:54am

vou abrir um branch e tentar reverter pra Hibernate3, pra ver se resolve.
Quaisquer outras idéias serão bem vindas!!

Valeu!!

rimolive · Abril 27, 2012, 10:21am

Olá ArturSampaio,

Sinceramente, não conheço muito de Spring mas tenho um conhecimento razoável no Hibernate 3 e 4 e acho que posso lhe ajudar. O que eu lhe peço é que se possível enviar a versão completa de cada framework que você utiliza e eu posso tentar criar um projeto de teste para verificar se isso realmente é um problema do Hibernate ou não e como tentar um workaround disso. É importante saber se não há nenhum módulo Spring dentro da sua aplicação e se tiver quais são.

Primefaces
Spring 3
Hibernate 4

Perceba que tenho dúvidas sobre como deve ser um método de DAO (e por isso tenho códigos comentados, try-catch, etc):

preciso lidar com a transação (tx.beginTransaction();tx.commit();etc)… ou o @Transactional vai cuidar disso sozinho?
se a transação for controlada pelo @Transactional, como devo lidar com Exceptions (por exemplo NoResultException, pra saber se o resultado não foi encontrado)

a arquitetura da aplicação está assim:
Interface de usuário (.xhtml) <–> BackingBean (@ViewScoped) <–> Service <–> DAO <–> Postgres

escolhi fazer uma camada de Service independente pra poder implementar webservices no futuro. senão o próprio backingBean poderia acessar o DAO

Fiz a experiência com Hibernate3, e o erro permanece.
Insisto em 2 possibilidades:
1 - o lazyLoading não está usando a mesma sessão que o OSIV mantém aberta
2 - o OSIV mantém a sessão apenas para RequestScope. o problema ocorre pq uso ViewScope

ou ainda uma 3a:

estou errando em algum ponto e ainda não enxerguei!!!

Muito obrigado a todos que tem ajudado!!

Fica bastante evidente que o OSIV está funcionando. Ele abre a sessão corretamente… Então só posso concluir que o lazy loading é que está fazendo algo errado e não enxerga a session aberta. Seria o caso de a entidade estar detached? alguma idéia?
