如何修复 Tomcat 部署 8.5.27 上出现的“java.lang.NoClassDefFoundError: javax/management/MBeanServerNotification”问题

Question

我在 tomcat 9 服务器上本地部署了我的项目，它工作得很好，但是当我尝试使用 tomcat 8.5.27 在远程部署服务器中执行相同操作时，它会抛出以下错误：

我使用java 1.8和springboot版本2.1.2。直到昨天，代码已在远程服务器上部署并正常运行，直到今天我才收到此错误。在我的 Tomcat 9 本地系统上，它仍然可以正常运行。我没有添加到 eclipse 中的构建路径中的其他依赖项。 请告诉我此错误的原因和解决方法。预先感谢。

Answer 1

我也遇到了同样的错误

Caused by:java.lang.NoClassDefFoundError: javax/management/MBeanServerNotification

当我在远程主机服务器上部署此应用程序时。应用程序在本地服务器上运行没有错误。两台服务器的操作系统都是Ubuntu 22.04。

我通过以下步骤摆脱了这个错误：

我在远程服务器上重新启动了 Tomcat。

1. 我在远程服务器上取消部署此应用程序。
2. 我将其 war 文件移至 /opt/tomcat/latest/webapps 文件夹。
3. 每次尝试都有效。
但是，在跳过步骤 1 和 2 时，我总是遇到上述错误。当我在 Tomcat 管理器中按下此应用程序旁边的启动按钮而不执行上述步骤时，我也遇到了该错误。

也许更新或升级 Tomcat 会使上述步骤变得不必要？一些人提到的其他解决方案在这种情况下不起作用。
