You have duplicate mappings for course and student, like:
@RequestMapping("/student")
And Index controller you have dublicate for /student:
@Controller
@RequestMapping("/")
public class IndexController {
@RequestMapping(value = "/index", method = RequestMethod.GET)
public String index() {
return "index";
}
**@RequestMapping(value = "/student"**, method = RequestMethod.GET)
public String aboutus() {
return "student";
}
RequestMapping(method = RequestMethod.GET) and @GetMapping are basicly same thing.
