Point of integration between Spring Portlet MVC and Spring Web Flow: a Controller that routes incoming portlet requests to one or more managed flow executions.

Requests into the web flow system are handled by a FlowExecutor , which this class delegates to. Consult the JavaDoc of that class for more information on how requests are processed.

Note: a single PortletFlowController may execute all flows within your portlet. See the phonebook-portlet sample application for examples of the various strategies for launching and resuming flow executions in a Portlet environment.

Usage example:

 <!--
     Exposes flows for execution.
 -->
 <bean id="flowController" class="org.springframework.webflow.executor.mvc.PortletFlowController">
     <property name="flowLocator" ref="flowRegistry"/>
     <property name="defaultFlowId" value="example-flow"/>
 </bean>
                                                                                          
 <!-- Creates the registry of flow definitions for this application -->
     <bean name="flowRegistry" class="org.springframework.webflow.config.registry.XmlFlowRegistryFactoryBean">
     <property name="flowLocations" value="/WEB-INF/flows/*-flow.xml"/>
 </bean>
 

It is also possible to customize the FlowExecutorArgumentExtractor strategy to allow for different types of controller parameterization, for example perhaps in conjunction with a REST-style request mapper.
