我有一个多模块项目，其中一个是GraphQL模块，Runnable文件在另一个模块中，有一个工作的RestController，GraphQLController没有暴露。我尝试将www.example.com移动application.properties到可运行模块没有工作，尝试移动GraphQLController也没有工作，我甚至将所有文件移动到可运行模块，什么也没有发生。我的依赖关系很好我的gradle很好我确信我的代码可以工作，但只是单独运行我尝试了它，它确实工作，但我正在处理一个多模块项目，所以我不能单独运行它。这里的问题是什么，我在谷歌上搜索了这个问题，并尝试了所有相关的解决方案。
