Could not start Spring MVC project

Question

I create a dynamic web project to develop a simple project, the first step I want to do is display the index page and show the title generate by controller. but it's always 404 status and no error or exception in log is there any problem?

APIController.java

@Controller
public class APIController {
@RequestMapping(value = "/index.web", method = RequestMethod.GET)
public String welcome(ModelMap model) {

    model.addAttribute("title", "AM Core Test");
    return "index";
    }
}

You have not implemented the interfaces for your controller as you added @Controller annotation, But you have failed to add its suppert in the Dispatcher-servlet

try adding ,

<mvc:annotation-driven />

in your dispatcher-servlet. Also it is enough to give the url pattern in the controller without extension as below

@Controller
public class APIController {
@RequestMapping(value = "/index", method = RequestMethod.GET)
public String welcome(ModelMap model) {

    model.addAttribute("title", "AM Core Test");
    return "index";
    }
}

Now try the URL as , http:\\\\ project_name\\index.web in your browser
