You have no mapping for controller. Now you have only /student as GET and /addStudent as POST. Even if you add @RequestMapping("/controller") to your controller class it will not work because there is still no mapping for /controller. As you can see mapping will be for /controller/student and /controller/addStudent. I recomend you to change requesting URL to just /student and /addStudent or if you need this /controller URL you should have additional method looks like below

@RequestMapping("controller")
public String anyMethodName(Model model) {
    //code goes here
    return "anythink";
}
