java - org.springframework.web.servlet.PageNotFound noHandlerFound警告: No mapping found for HTTP request with URI

Question

这个问题已经有答案了:

Why does Spring MVC respond with a 404 and report "No mapping found for HTTP request with URI [...] in DispatcherServlet"? (13 个回答)

已关闭 6 年前。

我是 Spring MVC 框架的新手。我正在尝试在 Eclipse Juno 和 Tomcat(V 7.0.61) 中使用 Spring 4 设置示例代码库。我尝试了不同论坛中所述的不同选项，但没有一个有效。非常感谢任何解决此问题的帮助!

下面是代码:

Web.xml

   </servlet>

   <servlet-mapping>

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

   @RequestMapping(method = RequestMethod.GET )
   public String printHello(ModelMap model) {


      model.addAttribute("message", "Hello Spring MVC Framework!");

      return "hello";
   }
}

您需要将其添加到您的web.xml

<context-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>/WEB-INF/HelloWeb-servlet.xml</param-value>
</context-param>

<listener>
   <listener-class>
      org.springframework.web.context.ContextLoaderListener
   </listener-class>
</listener>
