Means you are using spring boot first time and yet you did not mapped your route with your controller, So dont worry it is expected
Lets go to controller package and create controller
package com.manoj.techbrushup.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class ParentController {
@GetMapping("/")
public String index() {
return "index";
}
@GetMapping("signin")
public String signin() {
return "signin";
}
@GetMapping("signup")
public String signup() {
return "signup";
}
@GetMapping("profile")
public String profile() {
return "profile";
}
@GetMapping("home")
public String home() {
return "home";
}
}
