java - 在 Spring MVC 中使用 BeanNameUrlHandlerMapping 时找不到映射

Question

我正在尝试在Spring 4.0.3中使用BeanNameUrlHandlerMapping。我运行网络应用程序，一切正常。控制台日志中没有错误。

但我收到此警告消息:

Apr 22, 2014 9:47:48 AM org.springframework.web.servlet.PageNotFound noHandlerFound WARNING: No mapping found for HTTP request with URI [/springmvc_beanurlhandler/beanurhandlermapping.html] in DispatcherServlet with name 'dispatcher'

当我点击链接时，出现 404 错误页面。

这是我的代码:

Controller

public class BeanNameUrlHandlerMappingController extends AbstractController {

    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest request,
            HttpServletResponse response) throws Exception {
        // TODO Auto-generated method stub
        String message = "BeanNameUrlHandlerMapping invoked!";
        System.out.println(message);

        ModelAndView modelAndView = new ModelAndView("success");
        modelAndView.addObject("message", message);

        return modelAndView;
    }

}

  </servlet>

  <servlet-mapping>

    <url-pattern>*.html</url-pattern>
  </servlet-mapping>

</web-app>

以上是我的项目结构。

请帮忙，谢谢。

在dispatcher-servlet.xml中，您将 Controller 映射为:

    <bean name="/beanurlhandlermapping.html" class="com.fanjavaid.controller.BeanNameUrlHandlerMappingController" />

在index.jsp中将其更改为:

    <a href="beanurlhandlermapping.html">Click to test BeanURLHandlerMapping</a>
