Spring Integration

Hey thank you very much for your great tutorial! I can see in "app.security" there is an Interface "CurrentUser" annoted as @FunctionalInterface. Can you please explain how to use it? I tryed to Inject in MainView so I can get the "User" without calling Authentication = SecurityContextHolder.getContext().getAuthentication(); but I got this error;

There was an exception while trying to navigate to '' with the exception message 'Error creating bean with name 'org.vaadin.mordile.MainView': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.vaadin.mordile.app.security.CurrentUser' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}'

I was thinking (not sure if it's a BEST PRACTICE) that I could get the "User" in SecurityUtils.class implementing the method "isAccessGranted" as follow;

public static boolean isAccessGranted(Class<?> securedClass) {
		Authentication userAuthentication = SecurityContextHolder.getContext().getAuthentication();

		VaadinSession session = VaadinSession.getCurrent();
		session.setAttribute("user",userAuthentication.getName());

		// All views require authentication
		if (!isUserLoggedIn(userAuthentication)) {
			return false;
		}

thanks a lot!

A small correction.

Each browser tab does not have its own @VaadinSession beans.

Instead, each browser tab has its own @UIScope beans and shared @VaadinSession beans.

I have verified this with Vaadin 18.0.3
