Spring Hello World HTTP 状态 500 Servlet Init

标签 spring maven spring-mvc tomcat servlets

我是 Spring 的新手，并尝试按照本教程做我的第一个 Hello World 示例:https://www.youtube.com/watch?v=_-TxWzhc1g4 .不幸的是，当我尝试运行该应用程序时，我收到如下错误。我尝试在 Stack 的其他讨论中寻找解决方案，但没有成功。不幸的是，因为这是我第一次使用 Spring，所以我不知道可能导致错误的原因，因此我将非常感谢您的帮助。

最佳答案

错误很简单:

IOException parsing XML document from ServletContext resource [/WEB-INF/webmvc-dispatcher-servlet.xml]; 
nested exception is java.io.FileNotFoundException: 
Could not open ServletContext resource [/WEB-INF/webmvc-dispatcher-servlet.xml]

它就在那里说，它无法读取 /WEB-INF/webmvc-dispatcher-servlet.xml 文件。
在您的帖子中，您将其称为 webmvc-dispatcher-servlet2.xml，也许这就是问题所在？如果不是，请验证文件位于正确的文件夹中，具有正确的名称和足够的权限
