Spring Hello World HTTP状态500 Servlet Init

时间：2016-12-30 21:07:36

标签： spring maven spring-mvc tomcat servlets

我是Spring的新手，并尝试按照本教程进行我的第一个Hello World示例：https://www.youtube.com/watch?v=_-TxWzhc1g4。不幸的是，当我尝试运行应用程序时，我收到一个错误，如下所示。我尝试在Stack的其他讨论中找到解决方案，但我没有成功。不幸的是，因为这是我第一次使用Spring，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。

1 个答案:

答案 0 :(得分：1)

错误是直截了当的：

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]

它说它就在那里，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？如果没有，请验证该文件是否在正确的文件夹中，具有正确的名称和足够的权限
