<title>Mapping URLs to Flows</title>
<para>
The <code>DispatcherServlet</code> maps request URLs to handlers.
A simple way to create URL mapping rules is to define a <code>SimpleUrlHandlerMapping</code>:
A flow is one type of handler.
The simplest way to configure the Dispatcher to map to flows is to define a <code>FlowIdHandlerMapping</code>
</para>
<programlisting language="xml"><![CDATA[
<bean id="flowUrlMappings" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<value>
/hotels/booking=bookingFlowHandler
</value>
</property>
<bean id="flowUrlMappings" class="org.springframework.webflow.mvc.servlet.FlowIdHandlerMapping">
<property name="flowRegistry" ref="flowRegistry"/>
<property name="order" value="0"/>
</bean>]]>
</programlisting>
<para>
The example above maps the servlet-relative request URL <code>/hotels/booking</code> to the <code>bookingFlowHandler</code>.
Configuring this mapping allows the Dispatcher to map application resource paths to flows in a flow registry.
For example, accessing the resource path <code>/hotels/booking</code> would result in a registry query for the flow with id <code>hotels/booking</code>.
If a flow is found with that id, that flow will handle the request.
If no flow is found, the next handler mapping in the Dispatcher's ordered chain will be queried or a "noHandlerFound" response will be returned.
