Spring Events
List of events published to the Spring context.
The Spring integration publishes events to the application context. You don’t need to register a listener. It’s sufficient to handle these events using only the @EventListener annotation.
Events published to the Spring application context include:
ServiceInitEvent-
See VaadinServiceInitListener for details.
The example here uses the @EventListener annotation to listen to the ServiceInitEvent event:
@SpringComponent
public class BootstrapCustomizer {
@EventListener
private void onServiceInit(ServiceInitEvent serviceInitEvent) {
serviceInitEvent.addIndexHtmlRequestListener(
this::modifyBootstrapPage);
}
private void modifyBootstrapPage(
IndexHtmlResponse response) {
response.getDocument().body().append(
"<p>By Spring EventListener</p>");
}
}
