如何将一个Spring Boot应用程序作为另一个应用程序的依赖项引入

Question

我想知道这是否可行并且是否推荐。我的使用场景是，我有一个独立的项目A，具有我想要的所有核心功能。我还有一个包含项目A作为依赖项的项目B。项目B的basePackage与项目A相同，因此它可以捕获项目A的配置bean和控制器等。这正是我想要的，但我也想能够覆盖配置或扩展项目A的控制器。显然不能有多个映射，这就是结果。也许问题在于扩展了项目A的控制器并排除了扩展控制器。这种情况常见吗？有没有推荐的方法？

我觉得我可能漏掉了基础知识，如果这是我新接触Spring的基本内容，请谅解。谢谢！

我找到了一个过滤组件扫描包的答案： https://dev59.com/wGQo5IYBdhLWcg3wMtC2这使我能够排除我想要覆盖的控制器。仍然在思考是否有这种类型的Web应用程序组合概念，但到目前为止，它对我的用例很有效。 - happyhuman
