What do you mean link it to a database? You mean you want to store the info in say a MySQL db?

If you're a beginner, you'd better start with the basics of java and then move on to web development. I'll assume you're already using Spring, so you need:

• Create table in your db like 'users'
• Create User entity with @Entity annotation and declare all columns of 'users' table
• [Optional] Create UserCreateDto/UserReadDto, if you worrying about security.
• Create controllers layer to handling requests

• Also, don't forget to declar the dependency to your DB in build.gradle/xml

After that, I recommend using Thymeleaf to link controller and your login page

login.html:

<form th:action="@{/login}" method="post">
//code-code-code...
    </form>

UserController:

@Controller
@RequiredArgsConstructor
public class UserCreateController {
    @GetMapping("/login")
    public String loginPage() {
        return "user/login";
    }
}
