Spring servlet mapping not working

When I try to load http://localhost:8080/people I receive a 404 page not found error.

This is my servlet mapping iwthin web.xml : 

<servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/people/*</url-pattern>
</servlet-mapping>

Here is how I understand it works :

A url request to http://localhost:8080/people will be intercepted by the servlet "spring" and will invoke the class org.springframework.web.servlet.DispatcherServlet Is this correct ?

Do I need some additional configuration in order for this class to be loaded correctly ?

Update :

Here is the controller : 

@Controller
public class PersonController {

    @Autowired
    private PersonService personService;

    @RequestMapping("/")
    public String listPeople(Map<String, Object> map) {

        map.put("person", new Person());
        map.put("peopleList", personService.listPeople());

        return "people";
    }

    @RequestMapping(value = "/add", method = RequestMethod.POST)
    public String addPerson(@ModelAttribute("person") Person person, BindingResult result) {

        personService.addPerson(person);

        return "redirect:/people/";
    }

    @RequestMapping("/delete/{personId}")
    public String deletePerson(@PathVariable("personId") Integer personId) {

        personService.removePerson(personId);

        return "redirect:/people/";
    }
}

Do you have controller backing to support your GET response?

Something like this

@Controller
@RequestMapping(value = "/people")
public class LoginController {

    @RequestMapping(value = "/i_am_here", method = RequestMethod.GET)
    public String firstForm() {
        return "SHOW_ME_THE_JSP_PAGE";
    }
}

Based on above example, this will make your get URL request like -> /people/i_am_here

Method will be invoked and the response could be sent back in JSP.

Checkout this example under Github
