This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

Specified by:

afterPropertiesSet in interface InitializingBean

Throws:

Exception - in the event of misconfiguration (such as failure to set an essential property) or if initialization fails for any other reason

checkResourceExists

Parameters:

locale - the desired Locale that we're looking for

Returns:

false if the resource exists false if we know that it does not exist

Throws:

Exception - if the resource exists but is invalid (for example, could not be parsed)

resourceExists

public reactor.core.publisher.Mono<Boolean> resourceExists(Locale locale)

Deferred check whether the resource for the configured URL actually exists.

The default implementation calls checkResourceExists(Locale).

Parameters:
