Shared ApllicationContext抛出未初始化或已经关闭的BeanFactory

Question

我有两个应用，主Spring Boot应用程序及其库也在Spring Boot中创建。主项目需要使用库中定义的组件，并且库需要从主项目中获取ApplicationContext。

• A这是包含应用程序上下文的Spring Boot应用程序，并且已部署到Tomcat
• B此应用程序打包为jar文件，并用作应用程序B]中的maven依赖项

这里有两个问题：

1. A保留应用程序上下文并注册应用程序B中的所有bean（我可以在这里使用@Import或@ImportResource吗？）
2. B
使用来自A的应用程序上下文（我尝试使用ApplicationContextAware注入它，但它似乎无法正常工作）

问题是使用上述应用程序A

所述的解决方案，因此主应用程序抛出了：

有什么方法可以实现这一目标？我在这里想念什么？

您可以@ComponentScan将豆类放入主项目（A）的另一个项目（B）：
