Java - 如何知道/跟踪哪个类/lib 引用了特定的类

Question

作为 java/spring 升级的一部分，我们计划升级一些已弃用和旧的库。

它是一个 Spring Boot 微服务。作为升级的一部分，我们删除了

javax.servlet

并将其替换为

jakarta.servlet

。

因此，我们遇到了以下错误 - 微服务中的某些内部库/类引用了

javax.servlet

并且抛出了

ClassNotFoundException

。

我们无法找到哪个类/库指向该类 -

javax.servlet.http.HttpServletRequest

，因为以下异常并未指向引用该类的类/库。

是否有一个工具/机制可以找到项目中引用所有此类的位置，而不仅仅是项目代码，还有是否有任何内部库或依赖项正在使用它。 我们在当前项目代码库中进行了查找，但我们没有看到它被使用。可能是该服务使用的一些内部库。

有办法知道吗？

提前谢谢大家。
