JSF page redirecting from java bean

问题

Is there some way how to redirect page to other page from Java method?

I'm able only to forward it using:

FacesContext.getCurrentInstance().getExternalContext().dispatch("/foo.xhtml");

or using navigation-rules of faces-config.xml.

Do you have any ideas?

回答1:

Not sure what you're after, but the ExternalContext#dispatch() does only a forward, not a redirect. You'd like to use ExternalContext#redirect() instead.

externalContext.redirect("foo.xhtml");

or even external (which is not possible with dispatch)

externalContext.redirect("http://stackoverflow.com");

You'd normally like to do this in bean's action method.

Since you mentioned JavaScript in the comments, here's how you could redirect using JS:

window.location = "foo.xhtml";
// Or
window.location = "http://stackoverflow.com";

回答2:

FacesContext.getCurrentInstance().getApplication().getNavigationHandler().handleNavigation(FacesContext.getCurrentInstance(), null, "page.xhtml");

Works just as well.

回答3:

please try with the call to the following static function:

String url = "/meta/default/inbox"; // Your URL here

FacesContext.getCurrentInstance().getExternalContext().redirect(url);
