Programação Java
,
#1

Fala ai meus amigos, existe alguma maneira de configurar cors no vraptor 4 ? eu andei vendo uns tutoriais e cheguei a criar um corsInterceptor e um corscontroller e tenho um autenticacaoInterceptor tambem, entao coloquei o corsinterceptor para executar primeiro só que quando uso nao consigo que o sistema redirecione mais para o login e acaba nada carregando a pagina só pisca e nada acontece e não tenho nenhum log de error ou warn no console alguem ai ta por dentro?

Bom galera consegui resolver … para quem estiver com problemas vou passar o codigo do CORSInterceptor e do CORSController

CORSInterceptor

`
import javax.inject.Inject;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import br.com.caelum.vraptor.BeforeCall;
import br.com.caelum.vraptor.InterceptionException;
import br.com.caelum.vraptor.Intercepts;

@Intercepts(before = AutenticacaoInterceptor.class)
public class CORSInterceptor {

private HttpServletRequest request;
private HttpServletResponse response;

/**
 * @deprecated
 */
public CORSInterceptor() {}

@Inject
public CORSInterceptor(    HttpServletRequest request,
                        HttpServletResponse response ) {
    this.request = request;
    this.response = response;
}

@BeforeCall
public void intercept() throws InterceptionException {
     
    String origin = request.getHeader("origin") != null ? request.getHeader("origin") : "*";
     
    response.addHeader("Access-Control-Allow-Origin", origin);
    response.addHeader("Access-Control-Allow-Credentials", "true");
    response.addHeader("Access-Control-Expose-Headers", "Content-Type, Location");
}

}`

CORSController

`import java.util.Set;

import javax.enterprise.event.Observes;
import javax.inject.Inject;

import br.com.caelum.vraptor.Controller;
import br.com.caelum.vraptor.Options;
import br.com.caelum.vraptor.Path;
import br.com.caelum.vraptor.Result;
import br.com.caelum.vraptor.controller.HttpMethod;
import br.com.caelum.vraptor.events.VRaptorRequestStarted;
import br.com.caelum.vraptor.http.route.Router;
import br.com.caelum.vraptor.view.Results;

@Controller
public class CorsController {

private Result result;
private Router router;

/**
 * @deprecated
 */
public CorsController() { }

@Inject
public CorsController(Result result, Router router) {
    this.result = result;
    this.router = router;
}

@Options
@Path(value = "/*")
public void options(@Observes VRaptorRequestStarted requestInfo) {
         
    Set<HttpMethod> allowed = router.allowedMethodsFor(requestInfo.getRequest().getRequestedUri());
    String allowMethods = allowed.toString().replaceAll("\\[|\\]", "");
     
    result.use(Results.status()).header("Allow", allowMethods);
    result.use(Results.status()).header("Access-Control-Allow-Methods", allowMethods);
    result.use(Results.status()).header("Access-Control-Allow-Headers", "Content-Type, X-Requested-With, accept, Authorization, origin");
}

}`

Desse jeito o meu funcionou de boa
