(Resolvido)Vraptor 3, Daos e Spring (não funciona a injeção )

This message was edited 3 times. Last update was at 03/08/2011 10:55:00

Bom pessoal, percebi que é uma duvida muito comum entre iniciantes igual a mim com o Vraptor
antes que me perguntem (já gogleou?), a resposta é sim, to a 3 dias tentando.
valeu
entao vamos lá.......

oque fiz até agora,
criei interfaces para meus daos e meus controllers
criei uma classe abstrata pra cada um com uma implementação padrao

criei aqueles sessionfactory da apostila do vraptor
lá configurei meu hibernate. bem parecido com um tutorial do wbotelhos sobre controle de login.
até ai tudo bem..
se eu colocar no meu construtor do controller o dao o vraptor nao consegue instanciar o (usuarioDao)
se deixar somente o Result ele funciona...

sendo que meu usuarioDao só recebe a session (org.hibernate.session)

e nao funciona..
meu dao esta anotado como @Component
meu controller como Resource
meu bean esta funcionando com o bibernate numa clase teste que fiz(entao o problema nao é ele)

a exception é essa que já vi muitos com o mesmo problema, mas nao to conseguindo resolver...

alguma ajuda ? Dica que possa estar esquecendo... possivel bug na ultima versão do vraptor? valeuu

JavaEvangelist Membro desde: 25/09/2008 18:44:25 Mensagens: 434 Offline

Alguma possivel causa por nao estar criando o meu Dao sendo que ele esta anotado como Component e recebe uma session
criei os sesssionfactory, adicionei num SpringProvider...
o vraptor chama eles, adiciona,
o dao sozinho funciona também!!
so o Spring noa consegue inicializar ele!
Ajuda?!?

GUJ Hacker Membro desde: 08/07/2007 00:08:14 Mensagens: 6396 Offline

qual é a hierarquia de classes?

Dao é uma Interface?

se sim vc precisa que uma implementação dele esteja anotada com @Component

o ideal é ter:

e receber UsuarioDao no controller ou ter:

e receber UsuarioDao (a interface) no controller

Poisé, tenho a seguinte forma

Pelos exemlos que vi tinha que funionar assim...
e como falei na primeira postagem, uso as SessionFActory e registrei os provider como a apostila diz pra fazer...

(Sabe aquele problema que vc passa e pensa assim.."Caraca isso já consegui fazer funcionar por que agora não vai", to nessa!)
Abraços e obrigado pela dica...

estranho, vc tá recebendo UsuarioDao no construtor e tá dando erro que não achou o Dao?

JavaEvangelist Membro desde: 25/09/2008 18:44:25 Mensagens: 434 Offline

acho que dentre meus testes peguei uma stacktrace errada mas ele não acha o UsuarioDao. não consegue criar passando a session pra ela!

GUJ Hacker Membro desde: 08/07/2007 00:08:14 Mensagens: 6396 Offline

ah tá... vc tem algum componente que cria a Session? ou registrou a configuração de packages com o pacote do hibernate?

JavaEvangelist Membro desde: 25/09/2008 18:44:25 Mensagens: 434 Offline

tenho meu provider no web.xml

vc não precisa do seu SEntinelaProvider... só as anotações @Component são suficientes...

qual é o erro que está acontencendo? posta a stack aqui

agora to sem meus fontes aqui no trabalho, quando chegar em casa posto aqui, e por enquanto obrigado pela ajuda!

a classe UsuarioDao está dentro de um jar? ou está compilada com o resto da aplicação?

pq se ela está anotada com @Component não deveria dar esse erro

JavaEvangelist Membro desde: 25/09/2008 18:44:25 Mensagens: 434 Offline

Poisé meu amigo, ai esta meu dilema....
esta junto com a aplicação..
se retiro o UsuarioDao do construtor
o spring injeta certinho e chama meu index de UsuarioController.
me diz a versão dos teus jars do spring pra mim conferir.
to achando que pode ser isso!
abraços!

se quiser de mando meus projetos por e-mail

GUJ Hacker Membro desde: 08/07/2007 00:08:14 Mensagens: 6396 Offline

não é versão do spring... se o UsuarioDao está mesmo anotado com @Component do VRaptor deveria funcionar recebê-lo no construtor do controller...

tenta dar um clean no projeto e no servidor só pra garantir
