如何将一个 Spring Boot 应用程序作为依赖项包含在另一个应用程序中

Question

我想知道这是否可行和/或推荐。

我的用例是我有一个独立的项目 A，它拥有我想要的所有核心功能。我也有包含项目 A 作为依赖项的项目 B。项目 B 的 basePackage 与项目 A 相同，因此它获取项目 A 的配置 bean 和控制器等...这是我想要的，但我也希望能够覆盖配置或扩展项目 A 的控制器。不过，我不能有多个映射，这显然是结果。也许这是扩展 Project A 控制器并排除扩展控制器的问题。

这很常见吗？有推荐的方法吗？

我觉得我错过了一些基本的东西，如果这是我刚接触 Spring 的基本东西，我深表歉意。

提前致谢！

首先是我的核心项目
