的「Hello world」

我下面this tutorial跑進以下錯誤教程錯誤：的「Hello world」

> Jul 19, 2013 2:18:14 PM 
> org.springframework.web.servlet.DispatcherServlet noHandlerFound 
> WARNING: No mapping found for HTTP request with URI 
> [/Spring3MVC/hello.html] in DispatcherServlet with name 'spring'

我可以打開第一jsp文件（index.jsp），但是當我點擊「打招呼」就說明404給我。我嘗試了本教程評論中提出的方法，但他們沒有奏效。

我偏離教程的唯一地方是我使用的是Tomcat 7而不是6.其他所有的東西看起來都是使用Eclipse的。我的代碼與教程中的代碼相同，因此現在無需將其粘貼到此處。 :)

的hello.jsp中的文件路徑爲：

Spring3MVC\WebContent\WEB-INF\jsp\hello.jsp

的web.xml是：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
    id="WebApp_ID" version="2.5"> 
    <display-name>Spring3MVC</display-name> 
    <welcome-file-list> 
     <welcome-file>index.jsp</welcome-file> 
    </welcome-file-list> 

    <servlet> 
     <servlet-name>spring</servlet-name> 
     <servlet-class> 
      org.springframework.web.servlet.DispatcherServlet 
     </servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>spring</servlet-name> 
     <url-pattern>*.html</url-pattern> 
    </servlet-mapping> 
</web-app>

彈簧servlet.xml文件：

<?xml version="1.0" encoding="UTF-8"?>

Controller.java

package net.viralpatel.spring3.controller; 

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

@Controller 
public class HelloWorldController { 

    @RequestMapping("/hello.html") 
    public ModelAndView helloWorld() { 

     String message = "Hello World, Spring 3.0!"; 
     return new ModelAndView("hello", "message", message); 
    } 
}

變化吧'@RequestMapping（「/ hello「）'到'@RequestMapping（」/ hello.html「）'contoller。 –

沒有任何改變 –

你可以發佈你的代碼嗎？ –

您的文件被命名爲sprint-servlet.xml？也許這就是問題所在。

由於Sotirios Delimanolis指出，它應該以標籤命名，默認情況下。

該文件的名稱應該是spring-servlet.xml。

彈簧應用程序的一個示例是here。

正式的春季教程是here。

默認情況下，它應該以''標籤命名。 –

@SotiriosDelimanolis看看這個問題。提問者寫了「sprint-servlet.xml文件：」 –

對，告訴他如何解決它。我沒有糾正你。 –
