spring - 在 Liberty 中运行时 Spring Boot 服务未自动装配，但在 TomCat 中运行良好

问题描述

我有一个在使用内置 Tomcat 运行时运行良好的 Spring Boot 应用程序。当我排除内置 Tomcat 实例并在 IBM Liberty 中部署时，大多数服务/控制器都可以正常工作。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：

org.apache.tiles.el.ScopeELResolver NoClassDefFound 错误我在使用 Liberty 时在其他日志中的其他地方看到过，因此似乎不相关但不确定。虽然 BeanPostProcessor 很有趣，但也不确定是否存在（注释掉了类上的方法安全性，但它仍在发生）。

你知道为什么 Liberty 处理这些和 Tomcat 的方式会有什么不同吗？或者调试这个的任何提示？

谢谢你，马特

解决方案

结果是有问题的控制器端点（其中 3 个），由于某种原因缺少访问修饰符。在方法中添加保护解决了这个问题。这在 Tomcat 中不是问题，但只有在 Liberty 上运行时才会出现。再次感谢您的帮助（并为发布后不久休假而迟到的回复道歉）
