e como eu implementei no interceptor!
@Intercepts
public class AutorizacaoInterceptor implements Interceptor {
private final UsuarioWeb userWeb;
private final Result result;
private Recurso recurso;
public AutorizacaoInterceptor(UsuarioWeb userWeb, Result result, Recurso recurso) {
this.userWeb = userWeb;
this.result = result;
this.recurso = recurso;
}
@Override
public boolean accepts(ResourceMethod method) {
System.out.println("Metodo: "+method.getMethod().getName()+"\n");
return !method.containsAnnotation(Liberado.class);
}
@Override
public void intercept(InterceptorStack stack, ResourceMethod method,
Object resourceInstance) throws InterceptionException {
if(this.userWeb.isLogado()){
recurso.setNome("Administrar");
if (userWeb.getPrivilegio().getRecursos().contains(recurso)){
stack.next(method, resourceInstance);
}
recurso.setNome(method.getMethod().getDeclaringClass().getSimpleName()+"."+method.getMethod().getName());
if(this.userWeb.getPrivilegio().getRecursos().contains(recurso)){
stack.next(method, resourceInstance);
}
}
result.redirectTo(UsuarioController.class).logar();
}
}
E o exemplo de um metodo que da erro, mesmo com o usuario settado com o recurso correto, quando eu tento alterar!!
@Path("/privilegio/cadastrarAlterar")@Post
@DescricaoRecurso("Cadastra ou Altera os Privilegios")
public void cadastrarAlterar(List<Recurso> recursosList, Privilegio privilegio) throws Throwable {
//O Privilegio ja vem com o nome, portanto nao preciso seta-lo
//Aqui eu setto a empresa da qual o privilegio pertence (no caso a que foi carregada no login do usuario)
privilegio.setEmpresa(this.userWeb.getEmpresa());
/*Verifico se a lista estiver vazia para evitar o NullPointerException
* Aqui eu seto os recursos escolhidos para o objeto privilegio
* Como o hibernate trabalha com HashSet e o VRaptor com List eu preciso converter de List para HashSet*/
if (recursosList==null){
privilegio.setRecursos(new HashSet<Recurso>());
}else{
privilegio.setRecursos(new HashSet<Recurso>(recursosList));
}
/* Primeiro eu verifico se o o privilegio é novo ou já existe (cod==null "novo", cod!=null "ja existe")*/
if(privilegio.getCod()!=null){
//Se ja existe eu atualizo as informacoes no banco
this.privDao.mergePrivilegio(privilegio);
}else{
//Se for novo, eu cadastro no banco (O privilegio com seus recursos)
this.privDao.setPrivilegio(privilegio);
}
//Redireciona para a listagem de privilegios
result.redirectTo(PrivilegioController.class).privilegios();
}
