解决的办法是使用Spring的
ApplicationListener类而不是a
ServletContextListener，并专门监听
ContextRefreshedEvent。
这是我的工作示例：
@Componentpublic 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(); } }}
