Class ServletDeployer

java.lang.Object

com.vaadin.flow.server.startup.ServletDeployer

All Implemented Interfaces:

EventListener, javax.servlet.ServletContextListener

public class ServletDeployer
extends Object
implements javax.servlet.ServletContextListener

Context listener that automatically registers Vaadin servlets. The servlets registered are:

• Vaadin application servlet, mapped to '/*'
  The servlet won't be registered, if any VaadinServlet is registered already or if there are no classes annotated with Route annotation.
• Frontend files servlet, mapped to '/frontend/*'
  The servlet is registered when the application is started in the development mode or has Constants.USE_ORIGINAL_FRONTEND_RESOURCES parameter set to true.

In addition to the rules above, a servlet won't be registered, if any servlet had been mapped to the same path already or if Constants.DISABLE_AUTOMATIC_SERVLET_REGISTRATION system property is set to true.
