春天你好世界HTTP狀態500 Servlet初始化

Question

我是一個完整的新手春天，並嘗試做我的第一個Hello World示例遵循本教程：https://www.youtube.com/watch?v=_-TxWzhc1g4。不幸的是，當我嘗試運行該應用程序時，我收到如下錯誤。我嘗試在Stack的其他討論中找到解決方案，但是我沒有成功。不幸的是，因爲這是我第一次和Spring一起去，所以我不知道可能是什麼原因導致了錯誤，因此我將非常感謝您的幫助。

Answer 1

的錯誤是preety直截了當：

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] 

它說它在那裏，它不能讀取/WEB-INF/webmvc-dispatcher-servlet.xml文件。
在你的帖子中，你叫它webmvc-dispatcher-servlet2.xml，也許這是問題？如果沒有，請驗證該文件是否在正確的文件夾上，並且名稱正確並具有足夠的權限
