If you want to resolve a URL to a view, without a controller or action involved, you can do so too. For example if you wanted to map the root URL / to a GSP at the location grails-app/views/index.gsp you could use:

static mappings = {
      "/"(view:"/index")  // map the root URL
}

Alternatively if you need a view that is specific to a given controller you could use:

static mappings = {
   "/help"(controller:"site",view:"help") // to a view for a controller
}
