Spring 已收到通知，但数据未更新到iphone

我正在使用RESTfulWeb服务。因为我有一个方法，通过使用这个方法我发送通知和邮件。我的方法工作得很好，唯一的问题是，在调用此方法后获得成功响应前2,3秒会弹出通知

@Override
@Transactional

为此，我在sendNotificationToIOS方法中添加@Async注释，在添加此注释后它对我有效。需要添加到您的xml中。为此，我在sendNotificationToIOS方法中添加@Async注释，在添加此注释后它对我有效。需要添加到您的xml中，其实想做的。我认为sendNotificationToIOS可能会增加整个流程的开销，也可能导致异常，但如果sendNotificationToIOS失败，您仍然希望在restful服务响应中发送成功代码？如果它不影响响应，那么您发布的建议解决方案可能适合您的情况您还没有发布您真正想要做的事情。我认为sendNotificationToIOS可能会增加整个流程的开销，也可能导致异常，但如果sendNotificationToIOS失败，您仍然希望在restful服务响应中发送成功代码？如果它不影响响应，那么您发布的建议解决方案可能适合您的情况
