Duvida contexto jobScheduler

JavaGuru Membro desde: 29/10/2007 17:13:59 Mensagens: 246 Offline

Pessoal tenho um componente de jobScheduler
e anotei ele como

@ApplicationScoped

só que tento injetar um Dao no construtor e ele da NullpointerException na hora de executar , acho que nesse contexto a ID nã acontece

Tem algum contexto que ele faz a injeção de dependencia??
O componente vai rodar de 10 em 10 minutos fazendo algumas validações...

Lucas ta anotado com @Component sim pra fazer a injeção!!
Bom uma coisa foi erro meu , esqueci de passar no construtor por isso a NPE,mas mesmo assim o spring ta reclamando de outra coisa agora

Não entendi sua resposta de listener todo caso meu web.xml é esse ..da uma olhada..

o problema é que vc tá usando coisas Request scoped (o Dao) dentro de algo que é ApplicationScoped (o Scheduler)

vc não pode fazer isso... pelo menos ainda não é suportado pelo vraptor...

vc vai precisar que esse dao específico seja ApplicationScoped, receba uma SessionFactory no construtor, e abra (e feche) sessões quando for conveniente..

Entendi...beleza vo deixar o componente sem Injeção e instanciar na mão mesmo passando session e dando close ja que esse componente é pouco utilizado nesse escopo e muito mais no escopo de request...

Obrigado pela ajuda..

A minha solução pra esse problema q vc tem, e que já tive...

neste caso é sua responsabilidade cuidar desta sessão e fechala corretamente, para que ela não fique a deriva aberta comendo recurso...

Obs.... se for usar, chame o NoScopedSessionCreator no construtor do seu componente...
Use a sessão dentro do proprio construtor...
feche a sessão ainda dentro do contrutor... assim vc garante que não vai deichar o recurso aberto atoa...
