Hi,
Hi!
I have of course read the article at
http://tapestryjava.blogspot.com/2009/12/securing-tapestry-pages-with.html,
and i can't see any difference:
Component page = componentSource.getPage(pageName);
if (! page.getClass().isAnnotationPresent(RequiresLogin.class)) {
return false;
}
This doesn't work if you add the annotation after you started the
application. Another way of doing that, which works well with live class
reloading (you add, remove or change an annotation and it automatically
works) is using a worker. This is the one which handles the @Secure
annotation in Tapestry:
public class SecureWorker implements ComponentClassTransformWorker
{
public void transform(ClassTransformation transformation,
MutableComponentModel model)
{
Secure secure = transformation.getAnnotation(Secure.class);
if (secure != null)
model.setMeta(MetaDataConstants.SECURE_PAGE, "true");
}
}
You can get the ComponentModel of a given page or component instance using
getComponentResources().getComponentModel().
