Spring MVC應用程序不能與Tomcat和Eclipse一起工作

我在嘗試使用Spring Framework時遇到了很多麻煩，並且不知道錯誤在哪裏。我正在使用Tomcat 7.0.68部署應用程序。Spring MVC應用程序不能與Tomcat和Eclipse一起工作

當我嘗試使用URL（http://localhost:8080/fj21-spring/olaMundo）我得到一個404錯誤，但它應該被映射到打電話給我的行動方法上我的控制器類，如下：

package com.caelum.tarefas.controller; 

import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 

@Controller 
public class TarefasController { 

    @RequestMapping("/olaMundo") 
    public String execute(){ 
     return "ok"; 
    } 
}

我的聚甲醛。 xml文件是什麼如下：

</beans>

我希望有人可以幫助我。我曾嘗試在Eclipse中重新創建服務器，刪除了該項目並創建了另一個，但直到現在還沒有任何工作。

謝謝！

編輯

我對Controller類註釋改爲@RequestMapping後（值=「/ olaMundo」），Tomcat的寫在控制檯上一個堆棧跟蹤，它遵循（也許我太之前錯過了這個堆棧跟蹤）：

請不要發佈錯誤鏈接，而是直接將錯誤內容添加到您的問題。 – pczeus

也許你應該包含關於你如何嘗試訪問控制器方法的信息。什麼是你打的完整URL？你如何部署你的應用程序？它看起來在Tomcat上。這是一場戰爭嗎？爆炸戰爭？你的戰名是什麼？ – pczeus

編輯您的問題並複製Tomcat在Eclipse的選項卡「控制檯」中生成的堆棧跟蹤。 404錯誤沒有解釋任何東西，你可以刪除圖像。只需複製URL並記下它生成的404。 – RubioRic
