Q:

Can mule-restlet map a URL pattern to a specific method?

To translate an incoming http request to the specific method in Play! web framework is straight forward, which look like as follows:
GET    /users/{userId}  UserController.getUser   
POST   /users           UserController.addUser
PUT    /users           UserController.updateUser
DELETE /users/{userId}  UserController.deleteUser

But I find it hard to do this in Mule-Restlet.
<model name="userModel">
    <service name="userService">
        <inbound>
            <inbound-endpoint address="http://localhost:63080"/>
        </inbound>
        <outbound>
            <filtering-router>
                <outbound-endpoint address="vm://userController"/>
                <or>
                    <restlet:uri-template-filter pattern="/users/{userId}" verbs="GET"/>
                    <restlet:uri-template-filter pattern="/users" verbs="POST"/>
                    <restlet:uri-template-filter pattern="/users" verbs="PUT"/>
                    <restlet:uri-template-filter pattern="/users/{userId}" verbs="DELETE"/>
                </or>
            </filtering-router>
        </outbound>
    </service>
    <service name="userController">
        <inbound>
            <inbound-endpoint address="vm://userController"/>
        </inbound>
        <!-- **TODO: How to implement UserController** -->
        <component class="com.ggd543.mulerestletdemo.user.UserController"/>
    </service>
</model>

A:

According to the Restlet Transport doc, you should be able to shorten your routing map to:
<or-filter>
    <restlet:uri-template-filter pattern="/users" verbs="POST PUT"/>
    <restlet:uri-template-filter pattern="/users/{userId}" verbs="GET DELETE"/>
</or-filter>

Then to develop your UserController resource, refer to the Restlet's user guide that is relevant to the version in use by the transport.
