WebController.java

@Controller
public class indexController {
    String errorMessage = "Invalid credentials";

    @GetMapping("/login")
    public String login() {
        return "index.jsp";
    }

    /*********** Login using form ************/
    @RequestMapping(value = "/login", method = RequestMethod.POST)
    public String login(@RequestParam("firstname") String firstName,
            @RequestParam("lastname") String lastName) {
        System.out.println("inside login form");
        Customer object = repository.findByFirstNameAndLastName(firstName,
                lastName);
        if (object != null) {
            return "home.jsp";
        }
        return "index.jsp";
    }
}

index.jsp

<h3>Do Login Here</h3>
<form method="POST" action="/login">

        <tr>
            <td><input type="submit" value="Login" /></td>

    </table>
</form>

home.jsp
