Path VRaptor 3

djDufu · Julho 8, 2010, 5:12pm

Pessoal Estou com uma dúvida aqui em relação a organização e pastas do projetos, mais precisamente dos arquivos .jsp

Tenho a seguinte estrutura:

customer/broker/gridView.jsp
customer/broker/formView.jsp

No meu controller está anotado da seguinte maneira:

@Resource
@Path("/customer/broker")
public class BrokerController

Metodo:

@Get
@Path("/gridView")
public void gridView()

Quando chamo a seguinte url: “customer/broker/gridView” ele não encontra o recurso mostrando o link abaixo.

/einsurance/WEB-INF/jsp/broker/gridView.jsp

isso é algum tipo de configuração ou tenho que montar uma função de resolução de path?

valeu galera!

@Path indica qual URI está referenciando àquele método. Ou seja, seu método BrokerController.gridView() será chamando quando a URI /customer/broker/gridView for acessada.

Após finalizar na action será feito um forward para o JSP /WEB-INF/jsp/broker/gridView.jsp independente do Path usado. Ou seja, o que conta para o nome do JSP é o nome do controller e do método e não o @Path usado.

Obvio, isso é a configuração padrão, e você pode sobrescrever conforme for necessário.

Abraços

/einsurance/WEB-INF/jsp/broker/gridView.jsp [/quote]

Não entendi… você tem um link na página que aponta para esse local? Isso não funciona, você sempre deve acessar os JSPs pelas actions, e nunca o JSP direto.

Lucas_Cavalcanti · Julho 8, 2010, 5:57pm

vc precisa que seja essa a estrutura?

customer/broker/gridView.jsp
customer/broker/formView.jsp

não pode mover isso pra:

WEB-INF/jsp/broker/gridView.jsp
WEB-INF/jsp/broker/formView.jsp

?

djDufu · Julho 8, 2010, 6:07pm

Valeu pelas respostas pessoal.

Lucas a questão é que se eu deixar WEB-INF/jsp/broker/gridView.jsp o projeto ficará muito desorganizado, pois tenho dentro de customer algo em torno de 15 sub categorias entre outras.

na verdade minha sestrutura de paginas ficaria algo assim:

customer
   Broker
   Partner
   Subsidiary
   Channel
Policy
    blablablablabla
    blablablablabla
         blablablablabla
         blablablablabla
Products
Sales

e assim vai.

Lucas_Cavalcanti · Julho 8, 2010, 6:21pm

eu vou supor que vc vai usar o @Path que está na classe do seu controller pra decidir o prefixo dos jsps, vc mude isso se vc quiser…

crie uma classe com o mesmo conteudo dessa, só que com outro nome, num pacote da sua aplicação e anotada com @Component:

github.com

caelum/vraptor/blob/master/vraptor-core/src/main/java/br/com/caelum/vraptor/view/DefaultPathResolver.java

package br.com.caelum.vraptor.view;

import br.com.caelum.vraptor.http.FormatResolver;

This file has been truncated. show original

mude o método getPrefix para

protected String getPrefix(ResourceMethod method) {
    Path path = method.getResource().getType().getAnnotation(Path.class);
    return path.value();
}

daí seus jsps podem ficar relativos à pasta configurada no @Path da classe do controller

Valeu, Lucas.

o return path.value(); está nulo.

Lucas_Cavalcanti · Julho 8, 2010, 7:31pm

bom, retorna “/WEB-INF/jsp” qdo não vier o value então… ou qqer outro path que vc queira que seja o padrão…

o path.value() vai vir uma String[], que são as paths q vc colocou na anotação… usa isso pra retornar o que vc quer…

djDufu · Julho 8, 2010, 8:09pm

Lucas,

a função pathFor retorna getPrefix(method) + folderName + “/” + method.getMethod().getName()

porém a função getPrefix retornará minha nova notação /customer/broker e o foldername retorna o nome extraido do controller obtendo o seguinte resultado:

/einsurance/customer/brokerbroker/gridView.jsp

Lucas_Cavalcanti · Julho 9, 2010, 1:12pm

só remover o folderName…

pode mexer em todas as lógicas de montar os caminhos… só cuidado pra não mexer nas outras lógicas…

vc pode deixar essa classe do jeito que vc quiser

djDufu · Julho 13, 2010, 1:47pm

Cara valeu mesmo,

Fiz várias alterações na classe para tratar diferentes niveis.

Muito obrigado.

abs,

Eduardo Venâncio.
