How can I dynamically build a list of mappings - instead of:

class UrlMappings {
static mappings = {
   "/helpdesk/user/$action?/$id?" (controller="helpdeskuser")
   "/helpdesk/group/$action?/$id?" (controller="helpdeskgroup")
   "/helpdesk/company/$action?/$id?" (controller="helpdeskcompany")
   "/helpdesk/account/$action?/$id?" (controller="helpdeskaccount")
   "/admin/company/$action?/$id?" (controller="admincompany")
   "/admin/account/$action?/$id?" (controller="adminaccount")
 }
}

something like this pseudo code:

class UrlMappings {
static mappings = {
   application.controllerClasses.each {
     if(it.name.startsWith('helpdesk'))
        "/helpdesk/${it.name}/$action?/$id?" (controller="${it.name}")
     if(it.name.startsWith('admin'))
        "/admin/${it.name}/$action?/$id?" (controller="${it.name}")
   }
 }
}

(I don't understand what the static mappings are - a hash map? free variables?)

What I am trying to achieve are mappings based on the controller type - e.g. helpdesk, admin or user controllers. Once I have set up the mappings I want to add security based on URLs but I don't want to map each controller individually:

grails.plugins.springsecurity.interceptUrlMap = [
   '/helpdesk/**':   ['ROLE_HELPDESK','ROLE_ADMIN'],
]
grails groovy
