Why my view is not displayed. Spring boot - spring-boot

Question

I am creating a learning project, I can't figure out why my view is not showing on localhost.
I am saving those html files in main\resource\template
but still the html file is not rendered instead a string is showing up on the screen.
My Controllers
package com.blog.test.controllers;
import com.blog.test.entities.Users;
import com.blog.test.repository.UsersRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;
import java.util.List;
#RestController
public class Home {
#Autowired
UsersRepository usersRepository;
#GetMapping("index")
public String showHome(Model model) {
return "index";
}
#GetMapping("registration")
public String showRegistrationForm(Model model) {
Users users = new Users();
model.addAttribute("users", users);
return "registration";
}
}
my entities
package com.blog.test.entities;
import javax.persistence.*;
import java.time.LocalDateTime;
#Table(name = "POSTS")
#Entity
public class Posts {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int post_id;
#ManyToOne
private Users users;
private LocalDateTime created;
private String Title;
public Posts(){}
public Posts(int post_id, Users users, LocalDateTime created) {
this.post_id = post_id;
this.users = users;
this.created = created;
}
}
and
package com.blog.test.entities;
import lombok.Getter;
import lombok.Setter;
import javax.persistence.*;
import java.time.LocalDateTime;

public Users(){}
public Users(int userid, LoginInfo loginInfo, String name, LocalDateTime created) {
this.userid= userid;
this.loginInfo = loginInfo;
this.name = name;
this.created = created;
}
}

BUT nothing is coming up when I hit the localhost:8082\index
where do I get wrong.enter image description here

Answer 1

RestController annotation will return the json response not HTML or JSP.
#RestController = #Controller + #ResponseBody.
#RestController is used to create RESTful web services. For returning html or jsp, annotate the controller class with #Controller annotation.

Answer 2

Use #Controller instead of #RestController
#Controller
public class Home {
#Autowired
UsersRepository usersRepository;
#GetMapping("index")
public String showHome(Model model) {
return "index";
}
#GetMapping("registration")
public String showRegistrationForm(Model model) {
Users users = new Users();
model.addAttribute("users", users);
return "registration";
}
}
Difference between #Controller and #RestController is where we use when we need JSON_RESPONSE which we use in REST API.
and #Controller will return HTML and JS e.g View
