我有一個問題，我無法找到答案。Servlet在春季提交後無法訪問POST方法
通常情況下，我會使用IDE設置的所有內容作爲默認設置，但通過使用Spring MVC的要求，我必須刪除applicationContext.xml和dispatcher-servlet.xml以符合標準。當我做到這一點時，它停止工作，因爲web.xml文件，但我設法得到Servlet的GET方法，但在我使用POST方法的時候，它拋出「請求的資源不可用」。錯誤。
如何在不顯示此錯誤的情況下使用POST方法？
這是我的index.jsp文件

請檢查並讓我們知道RecibirDatos類中的doPost（）是否被調用？ – Mudassar
另外我有點好奇你是如何構建該項目，因爲你正在使用.. /撥打電話 – Mudassar
