org.springframework.webflow.mvc.servlet.FlowHandlerMapping

Implementation of {@link org.springframework.web.servlet.HandlerMapping} that follows a simple convention forcreating URL path mappings from the ids of registered {@link FlowDefinition flow definitions}. This implementation returns a FlowHandler that invokes a flow if the current request path matches the id of a flow in the configured {@link FlowDefinitionRegistry}. Alternatively, a custom {@link FlowHandler} may also be registeredwith in containing ApplicationContext with that id and it will be returned. This allows for more control over the invocation of a flow from Spring MVC environment. Null is returned in the case of no flow id match, allowing the next handler mapping in the chain to execute. @author Keith Donald
