在web.xml中執行maven Spring web mvc時出現異常

在使用spring mvc和maven依賴管理時運行代碼後得到下面的異常。任何人都可以幫忙嗎？經過上回答以下鏈接在web.xml中執行maven Spring web mvc時出現異常

，但毫無效果。

已經執行/運行應用程序，而不使用maven通過將jar添加到lib文件夾它工作正常，但是當使用maven它拋出此異常。 MI將Maven依賴關係檢查到部署程序集，並且它們出現在該位置。我是初學者。如果有任何建議，請讓我知道。

這類錯誤的最常見原因是您通過Maven直接或通過依賴關係導入了多個相同類的版本，因此在運行時從錯誤類路徑中選擇了錯誤的類。或者您導入了Tomcat容器已經提供的一些servlet類。嘗試從依賴關係中排除一些工件。或者這裏是我使用的servlet依賴關係，並且它與您的類似配置沒有任何問題。
