警告：未找到与URI Spring框架的HTTP请求映射

我得到错误：HTTP Status 404
用的警告：以下警告：未找到与URI Spring框架的HTTP请求映射

WARNING: No mapping found for HTTP request with URI [/p2/] in DispatcherServlet with name 'HelloWeb'

是我的文件：

HelloController.java

package pack1; 

import org.springframework.stereotype.Controller; 
import org.springframework.ui.ModelMap; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 

@Controller 
@RequestMapping("/") 
public class HelloController{ 

    @RequestMapping(method = RequestMethod.GET) 
    public String printHello(ModelMap model) { 
     //model.addAttribute("message", "Hello Spring MVC Framework!"); 
     return "hello"; 
    } 

}

HelloWeb-servlet.xml

     <property name="suffix" value=".jsp" /> 
    </bean> 

</beans>

的web.xml

<web-app id="WebApp_ID" version="2.4"

你需要添加方法 “你好” 到您的HelloController –

你如何打电话给你的控制器？ – Jens

添加@RequestMapping("/p2")的控制器，如下图所示：

@Controller 
@RequestMapping("/p2") 
public class HelloController{ 

    @RequestMapping(method = RequestMethod.GET) 
    public String printHello(ModelMap model) { 
     //model.addAttribute("message", "Hello Spring MVC Framework!"); 
     return "hello"; 
    } 
}

我改为@RequestMapping（“/ p2”），但仍然给出相同的错误 –
