public class SpringServlet
extends VaadinServlet

SpringServlet

public SpringServlet(org.springframework.context.ApplicationContext context,
                     boolean rootMapping)

Creates a new Vaadin servlet instance with the application context provided.

Use true as a value for forwardingEnforced parameter if your servlet is mapped to the root ("/*"). In the case of root mapping a RootMappedCondition is checked and VaadinServletConfiguration is applied conditionally. This configuration provide a ServletForwardingController so that other Spring endpoints may co-exist with Vaadin application (it's required since root mapping handles any request to the context). This is not needed if you are using non-root mapping since are you free to use the mapping which doesn't overlap with any endpoint mapping. In this case use false for the forwardingEnforced parameter.

Parameters:

context - the Spring application context

rootMapping - the incoming HttpServletRequest is wrapped in ForwardingRequestWrapper if true and push URL is prefixed with VaadinServletConfiguration.VAADIN_SERVLET_MAPPING
