public class HelloController  extends AbstractController{


    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest arg0,
            HttpServletResponse arg1) throws Exception {

        ModelAndView modelview= new ModelAndView("HelloPage");
        modelview.addObject("welcomeMessage","Hi there user this is my own written message");

        return modelview;
    }

}

here is my class path stack

i dont think there is a problem with the running of tomcat server because console log shows it as started.Still cant figure out why the resource can't be located..... Any help would be great

回答1:

The reasons for this may be-

  1. Make sure the path specified in spring-dispatcher.xml file for your views is correct (/WEB-INF/)

  2. While making the ModelAndView object in the HelloController, you are specifying the correct file name.



回答2:

Remove the following line from your spring-dispatcher.xml

<bean name="/welcome.html" class="com.rohit.hellocontroller.HelloController"/>

Update with the following in your HelloController:

@Controller
public class HelloController{
      @RequestMapping("/")
      public ModelAndView handleRequestInternal(HttpServletRequest arg0,
                    HttpServletResponse arg1) throws Exception {
               return new ModelAndView("HelloPage","welcomeMessage","Hi there user this is my own written message");

            }
    }
