java - Spring MVC 找不到处理程序

Question

我是 spring mvc 的新手，正在尝试开发一个非常基本的登录 Web 应用程序。运行项目时出现以下错误。自过去两周以来，我几乎尝试了所有方法，但无法修复此错误。请有人帮助我。

May 21, 2013 2:37:12 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/SpringWeb/WEB-INF/jsp/loginnn.jsp] in DispatcherServlet with name 'spring'

我的 jsp 页面位于 WEB-INF/jsp 下。我的 Controller 中的登录页面方法正在被调用，但 View 名称没有被渲染和解析。非常感谢您的帮助。

<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />

</beans>

Controller 类

@Controller

public class Firstcontrol {

@RequestMapping(value="/")
public ModelAndView invokeme(Model m)
{

ModelAndView mav=new ModelAndView();
mav.setViewName("result");
System.out.println("In method");
return mav;
}

@RequestMapping(value="/submit" ,method=RequestMethod.GET)
public String submit(Model m)
{
System.out.println("In submitmethod");
return "submit";
}
}

由于您将 DispatcherServlet 映射到“/”，请尝试添加 <mvc:default-servlet-handler/>给您spring-servlet.xml
