如何在java中部署Web应用程序

章乐逸
2023-03-14

我想在服务器上部署一个spring mvc中的Java web app build。我使用的是MilesWeb服务器。在尝试将应用程序部署到服务器后，我收到了以下异常日志，描述如下:“服务器遇到内部错误，导致无法满足此请求”。我需要帮助来找出我做错了什么。

从错误“嵌套异常是java.lang.UnsupportedClassVersionError”中可以看出，java不匹配。要么使用旧的tomcat，要么使用新的spring，反之亦然。要解决这个问题，请使用与java版本对应的spring和tomcat版本。

服务器的Java版本太旧。您必须在服务器上升级java。
