Htto 404錯誤：資源未找到 - STS

我是Java Spring MVC的新手。我創建了一個示例項目，但我似乎得到資源未找到錯誤Htto 404錯誤：資源未找到 - STS

@ Lilith2k3嗨，我還提供了web.xml file.please有web.xml中看看 – user1274646 2013-05-02 16:02:45

我不確定這是你問題的根源，但是你的代碼至少有兩個錯誤。

你需要指定「豆」字頭在你的servlet-context.xml的bean的條目。

<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
    <beans:property name="prefix" value="/WEB-INF/views/" /> 
    <beans:property name="suffix" value=".jsp" /> 
</beans:bean>

您的list.jsp中的tramp變量沒有「key」和「value」屬性，因爲它的類型是String。

<c:forEach var="tramp" items="${tramps}"> 
    <tr> 
     <td>${tramp}</td> 
    </tr> 
</c:forEach>

希望這會有所幫助。

的List.jsp嘿感謝提mistakes.but IM仍然得到同樣的error.is它DAT IM做一些錯誤，而重新運行project.i轉到list.jsp頁面 - >右鍵單擊 - >運行 - >在服務器上運行。這是wat我做的。 – user1274646 2013-05-02 16:28:28

基於要共享的網址，你正在使用錯誤的URL，你必須使用

localhost:8080/myapp/tramps

不

localhost:8080/myapp/WEB-INF/views/tramps/list.jsp

調用控制器的方法，如果你在Spring MVC中的新請我YT channel

萬一他的應用程序響應localhost：8080;） – 2013-05-02 18:20:21

@Bobo Zohdy如何設置此網址？ – user1274646 2013-05-03 12:07:14

你正在使用@RequestMapping（value =「/ tramps」，method = RequestMethod.GET）這是映射「/ tramps」到這個控制器的方法，如果你是新的春天MVC檢查我的YT頻道這裏http://www.youtube .COM /播放列表？列表= PL7350712B99EFC5DD – 2013-05-03 13:02:39
