public class DelegatingMessageSource extends MessageSourceSupport implements HierarchicalMessageSource
MessageSource that delegates all calls to the parent MessageSource.
If no parent is available, it simply won't resolve any message.
Used as placeholder by AbstractApplicationContext, if the context doesn't define its own MessageSource. Not intended for direct use in applications.
