It is a handy way to configure the VaadinServlet that is automatically introduced by Vaadin Spring. Here are couple of example which can be configured: * `vaadin.servlet.productionMode=true` * `vaadin.servlet.heartbeatInterval=60` * `vaadin.servlet.closeIdleSessions=true` For full list of available properties, see https://github.com/vaadin/spring/blob/3.0/vaadin-spring-boot/src/main/java/com/vaadin/spring/boot/internal/VaadinServletConfigurationProperties.java[VaadinServletConfigurationProperties].
