解决的办法是使用Spring的ApplicationListener类而不是aservletcontextlistener，并专门监听ContextRefreshedEvent。
这是我的工作示例：
@Component
public class MessagingApplicationListener implements ApplicationListener<ContextRefreshedEvent>, Notifiable {
private final NotifierFactor notifierFactory;
private final MessageSendingOperations<String> messagingTemplate;
private Notifier notifier;
@Autowired
public MessagingApplicationListener(NotifierFactor notifierFactory, MessageSendingOperations<String> messagingTemplate) {
this.notifierFactory = notifierFactory;
this.messagingTemplate = messagingTemplate;
}
@Override
public void onApplicationEvent(ContextRefreshedEvent event) {
if (notifier == null) {
notifier = notifierFactory.create(this);
notifier.start();
}
}
public void notify(NotifyEvent event) {
messagingTemplate.convertAndSend("/topic/greetings", new Greeting("Hello, " + event.subject + "!"));
}
@PreDestroy
private void stopNotifier() {
if (notifier != null) {
notifier.stop();
}
}
}
