    @RequestMapping(value="/hello",method=RequestMethod.GET)
    public String helloWorld(ModelMap model){
        model.addAttribute("message", "hello world");
        return "hello";

    }

The Handlermapping is missing in the context file, too. So add annotation-driven bean on top of what Kamlesh suggested.

<mvc:annotation-driven />

You are adding wrong servlet class in web.xml.

<servlet-class>com.Spring.Hello</servlet-class>

It should be :

 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
