Class VaadinServletConfiguration

java.lang.Object
  com.vaadin.spring.boot.internal.VaadinServletConfiguration

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean

@Configuration
@EnableConfigurationProperties(value=VaadinServletConfigurationProperties.class)
public class VaadinServletConfiguration
extends Object
implements org.springframework.beans.factory.InitializingBean

Spring configuration that sets up a SpringVaadinServlet. If you want to customize the servlet, extend it and make it available as a Spring bean.

By default, unless a custom mapping of the Vaadin servlet is performed using the URL mapping configuration property VaadinServletConfigurationProperties.getUrlMapping(), the Vaadin servlet is mapped to a hidden path not to block requests destined to DispatcherServlet. ServletForwardingController is then mapped so that requests to all SpringUI paths are forwarded to the servlet for the generation of a bootstrap page, which internally uses the Vaadin servlet path for all other communication.

This approach currently relies on a hack that modifies request servlet path and path info on the fly as those produced by ServletForwardingController are not what VaadinServlet expects. See SpringVaadinServlet for more information on this.
