Grails facebook graph plugin to check session in every controller

I'm using grails and facebook graph plugin for the user registration. However, instead of checking facebook session in every action and controller开发者_开发知识库. Is there a better way to check the session before entering controller? So, I don't have to duplicate the code to check authentication.

class FacebookSecurityFilters {

    def filters = {
        all(controller:'*', action:'*') {
            before = {
                println "test"
            }
            after = {

            }
            afterView = {

            }
        }
    }
}

I created this filter by using command grails create-filters . But it's not fired at all, I mean it didn't print "test" at all. Do I need to register the filter? I'm using Grails1.4M01

Thanks

Use a filter - it's a great way to intercept all actions, or a subset of actions based on a pattern: http://grails.org/doc/latest/guide/6.%20The%20Web%20Layer.html#6.6%20Filters
