调度程序 servlet 上下文在 Spring 上下文刷新后创建 bean，而不是使用"parent"

Question

当应用程序启动时，将引发两个上下文：一个用于org.springframework.web.context.WebApplicationContext事件，另一个用于org.springframework.web.context.WebApplicationContext:/dispatcher事件，并且一切正常，dispatcher上下文使用"父"；而不是自己创造。当我使用ConfigurableApplicationContext::refresh()启动spring上下文刷新时(我使用rest api请求调用它(，只发送一个ContextRefreshEvent(第一个(，并且当我尝试访问任何servlet组件(rest控制器(时，dispatcher开始创建他自己的bean，尽管存在"beans"；主"；刷新后创建的bean。并且再次没有事件被发送给调度程序上下文刷新。我需要创建dispatcher上下文，以便使用刷新的web应用程序上下文中的bean，而不是创建自己的bean。我认为问题是因为调度程序上下文没有用主上下文刷新。也许它甚至不知道刷新的上下文已经被提出。

Answer 1

对于其他想知道这个问题答案的人来说，这就是我解决问题的方法

我创建了实用程序类来存储应用中的所有ApplicationContext

public class ApplicationContextUtils
{
public static final Set<ApplicationContext> AppContexts = new LinkedHashSet<>();
}

然后我编写了一个类来处理所有ContextRefreshed事件，并将相应的上下文放在实用程序类中的集合中

@Component
public class ContextRefreshedEventsHandler implements ApplicationListener<ContextRefreshedEvent>
{
@Override
public void onApplicationEvent( ContextRefreshedEvent event )
{
ApplicationContext app = event.getApplicationContext();
ApplicationContextUtils.AppContexts.add( app );
}
}

因此，当应用程序启动时，所有上下文都按照出现的顺序存储在我的实用程序类中。在我的RefreshService中，我遍历所有上下文并刷新它们

List<ApplicationContext> appContexts = new ArrayList<>( ApplicationContextUtils.AppContexts );
for( ApplicationContext applicationContext : appContexts )
( (ConfigurableApplicationContext)applicationContext ).refresh();

这解决了的问题
