你採取了什麼行動，給你那個錯誤信息？它是在啓動時，HTTP GET還是其他內容中顯示的？ – chrylis

我正在訪問默認主頁，即http：localhost：8080/EnhancedRoyaltyTool /。 –

添加<mvc:default-servlet-handler/>我在調度員的servlet有固定的問題

原因是Spring找不到你的控制器，把它添加到你的xml配置中： – zengsn

這是URI的問題。你如何調用這個servlet？

你能否更詳細地解釋我？我試圖訪問默認的http：localhost：8080/EnhancedRoyaltyTool/page –

你告訴servlet容器在servlet-mapping，你想在Spring調度附着/，你告訴春天的printHelloWorld方法應該用於辦理/相對於servlet的基礎（這只是/）請求。但是你試圖加載/EnhancedRoyaltyTool/，並且你還沒有告訴servlet容器或Spring在那裏附加任何東西。您可以將RequestMapping更改爲"/EnhancedRoyaltyTool/"，將整個Spring servlet移動到servlet-mapping中的"/EnhancedRoyaltyTool/*"，或者嘗試訪問。

我對春天很陌生，但是，我假設我的pom創建了War EndhancedRoyaltyTool，並且默認情況下將其加載爲http：localhost： 8080/EnhancedRoyaltyTool /當我部署應用程序 –

這取決於如何設置容器。事實上，你從Spring獲得一個錯誤（而不是容器中的錯誤）意味着容器將請求指向Spring，但Spring仍然在路徑中看到「EnhancedRoyaltyTool」的事實意味着請求是相對於servlet根目錄，必須是'/'。你從來沒有發佈完整的錯誤信息，但我正確地猜測你得到了404嗎？ – chrylis

是的，我收到了404錯誤。 –

首先，檢查調度的Servlet。如果你還檢查它，然後，簡單的方法：你不需要通過構建路徑添加外部罐子。轉到項目工作區的文件夾，並直接複製下載的罐子並粘貼到：

WebContent>WEB-INF>lib>(here directly paste your jar files.) 

-> stop your application server (like tomcat); 
-> go to your IDE -> Select Project -> Clean Project builds

之後，你去：運行你的項目。我希望它能起作用！
