Spring 在 Liberty 中 运行 时引导服务未自动连接，但在 TomCat 中工作正常
Spring Boot Service not Autowired when running in Liberty, but works fine in TomCat
我有一个 Spring 启动应用程序，它在 运行 内置 Tomcat 时运行良好。当我排除内置 Tomcat 实例并在 IBM Liberty 中部署时，大多数 services/controllers 工作正常。但是，我的 2 个服务无法自动装配，在调用它们时收到 NPE。
我看到的日志是：
实际错误

org.apache.tiles.el.ScopeELResolver NoClassDefFound 错误我在使用 Liberty 时在其他日志的其他地方看到过，所以看起来不相关但不确定。 BeanPostProcessor 的虽然很有趣，但也不确定（在 class 上注释掉方法安全性，但它仍在发生）。
您知道为什么 Liberty 处理这些内容的方式与 Tomcat 有什么不同吗？或者有什么调试技巧吗？
谢谢，

原来控制器端点有问题（其中 3 个），由于某种原因缺少访问修饰符。将 protected 添加到方法中可以解决问题。这在 Tomcat 中不是问题，但仅当在 Liberty 上 运行 时才存在。再次感谢您的帮助（并为发布后不久就去度假而迟到的回复表示歉意）
