convert URI into grails controller and action name in servlet filter

[Bakhtiyor Khodjayev]

Hello, user.

    How to convert URI into controller and action name?

    So I need grails controller and action name in servlet filter.
Looking at grails source I found that with UrlMappingsHolder it
possible to obtain UrlMappingInfo that requieres GrailsWebRequest
(GrailsWebRequestFilter put GrailsWebRequest into servlet context)

    I think putting servlet filter after GrailsWebRequestFilter solve
converting issue (ant getting UrlMappingsHolder via grails
application context). Is it wrong?

    In xml parameter (of plugin script doWithWebDescriptor closure) I
can't (manage to) find GrailsWebRequestFilter entry to put my servlet
entry after it.


class SimpleCacheGrailsPlugin {
    ...
    def loadAfter = ['controllers']
    ...
    def doWithWebDescriptor = { xml ->
        if (manager?.hasGrailsPlugin("controllers")) {
            def webRequestFilter = null;
            xml.filter.each { f ->
                if (f ==
                'org.codehaus.groovy.grails.web.servlet.mvc.GrailsWebRequestFilter') {
                    webRequestFilter = f;
                }
            }
            //failed
        ****assert(webRequestFilter != null);****
        }
    }
    ...
}

    Or maybe is there a more simple way?

Yes you need to put your filter after the URL mapping one. Then use
the Spring RequestContextHolder object

def webRequest = RequestContextHolder.currentRequestAttributes()
println webRequest.controllerName
println webRequest.actionName

Cheers
