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

我不确定这是你问题的根源，但是你的代码至少有两个错误。

你需要指定“豆”字头在你的servlet-context.xml的bean的条目。

<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变量没有“key”和“value”属性，因为它的类型是String。

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

希望这会有所帮助。

的List.jsp嘿感谢提mistakes.but IM仍然得到同样的error.is它DAT IM做一些错误，而重新运行project.i转到list.jsp页面 - >右键单击 - >运行 - >在服务器上运行。这是wat我做的。 – user1274646 2013-05-02 16:28:28

基于要共享的网址，你正在使用错误的URL，你必须使用

localhost:8080/myapp/tramps

不

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

调用控制器的方法，如果你在Spring MVC中的新请我YT channel

万一他的应用程序响应localhost：8080;） – 2013-05-02 18:20:21

@Bobo Zohdy如何设置此网址？ – user1274646 2013-05-03 12:07:14

你正在使用@RequestMapping（value =“/ tramps”，method = RequestMethod.GET）这是映射“/ tramps”到这个控制器的方法，如果你是新的春天MVC检查我的YT频道这里http://www.youtube .COM /播放列表？列表= PL7350712B99EFC5DD – 2013-05-03 13:02:39
