Shall I know , Why the --------------- Context Refreshed ----------------- message comes twice ?
Edit : I know there are many ways to initialize an spring application. But what is the best and the efficient way to initialize an Spring application like logger,Domain server startup to get protocol connection , stating the threads etc... ?
Hope , you all can understand my question.

Its getting refreshed for each context, Dispatcher and Application. Try running this test:
public void onApplicationEvent(ContextRefreshedEvent event) {
ApplicationContext context = event.getApplicationContext();
System.out.println(context.getDisplayName());
}
