我正在使用Spring MVC創建一個小型Web應用程序。當我嘗試點擊一個似乎正確映射到我的控制器中的URL時，我得到一個404。我嘗試點擊/ projectname/test-，這是當我嘗試這樣做時在日誌中顯示的內容：Spring MVC - 在名爲'appServlet'的DispatcherServlet中找不到具有URI [/ demo/test]的HTTP請求的映射
警告：org.springframework.web.servlet.PageNotFound - 沒有在DispatcherServlet的發現HTTP請求的URI與[/演示/測試]名爲「appServlet」
我見過很多類似的問題被詢問的映射，但是沒有任何建議的修補程序適用於我。我使用的是Spring MVC，而服務器似乎無法解析通過瀏覽器進入的URL。奇怪的是「/ projectname」很好用，但「/ projectname/test」似乎根本不起作用。 JSP中都在同一個目錄中（src /主/ web應用/ WEB-INF /視圖/）具有下列名稱：
針對home.jsp，test.jsp的，userInfo.jsp
這裏是我的代碼：

}任何想法？我需要提供更多信息嗎？謝謝！
我的推薦。遠離XML-s。如果你想要一個小型的Web應用程序，請考慮Spring Boot。 – Vaelyr 2014-09-29 18:39:56
