(Quick Reference) # 8.4.1 Mapping to Controllers and Actions Version: 3.2.8 ## 8.4.1 Mapping to Controllers and Actions To create a simple mapping simply use a relative URL as the method name and specify named parameters for the controller and action to map to:
    "/product"(controller: "product", action: "list")
In this case we’ve mapped the URL `/product` to the `list` action of the `ProductController`. Omit the action definition to map to the default action of the controller:
    "/product"(controller: "product")
An alternative syntax is to assign the controller and action to use within a block passed to the method:
    "/product" {
        controller = "product"
        action = "list"
    }
Which syntax you use is largely dependent on personal preference. If you have mappings that all fall under a particular path you can group mappings with the `group` method:
    group "/product", {
        "/apple"(controller:"product", id:"apple")
        "/htc"(controller:"product", id:"htc")
    }
You can also create nested `group` url mappings:
    group "/store", {
        group "/product", {
            "/$id"(controller:"product")
        }
    }
To rewrite one URI onto another explicit URI (rather than a controller/action pair) do something like this:
    "/hello"(uri: "/hello.dispatch")
Rewriting specific URIs is often useful when integrating with other frameworks. | Quick Reference (hide)
