Question

我正在研究基于嵌入式Jetty，Spring和mongo的简单服务器。我为客户端公开了简单的休息接口。服务器在Windows平台上运行正常但是当我想在Linux上运行它时发生了一些奇怪的事情。当我尝试在服务器上调用任何REST API时，我得到以下错误。

我无法弄清楚这种情况的原因是什么。真正奇怪的是，同样的jar在Windows平台上正常工作，但在Linux上却没有。我通过java -jar server.jar启动服务器。我尝试在Raspberry PI和CentOS上运行它，它总是在客户端调用REST API时抛出NullPointerException。我将pom中的所有依赖项更新到所有库的最新版本，但它没有帮助。有人遇到过类似的问题吗？

提前感谢您的帮助。
