Question

I am developing a Java application with Spring Boot, however, Controller is not able to find HTML, apparently...

Page not being found

Previsão do tempo

Login controller that directs the page

package br.usjt.previsao.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.servlet.ModelAndView;
import br.usjt.previsao.model.Usuario;
import br.usjt.previsao.service.UsuarioService;

@Controller
public class LoginController {
@Autowired
private UsuarioService loginService;

@GetMapping(value = { "/login", "/" })
public ModelAndView login() {
    ModelAndView mv = new ModelAndView("login");
    mv.addObject(new Usuario());
    return mv;
}

@PostMapping("/fazerLogin")
public String fazerLogin(HttpServletRequest request, Usuario usuario) {
    if (loginService.logar(usuario)) {
        request.getSession().setAttribute("usuarioLogado", usuario);
        return "redirect:index";
    } else {
        return "login";
    }
}
}

Controller of the main application

package br.usjt.previsao.controller;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.servlet.ModelAndView;
import br.usjt.previsao.model.PrevTempo;
import br.usjt.previsao.service.PrevService;

public class PrevController {
@Autowired
private PrevService prevservice;

@GetMapping ("/previsao")
public ModelAndView listarPrev() {
    ModelAndView mv = new ModelAndView("index");
    mv.addObject(new PrevTempo());
    List<PrevTempo> prev = prevservice.listardias();
    mv.addObject("previsao", prev);
    mv.addObject(new PrevTempo());
    return mv;
}
 // MÉTODO PARA RETORNAR A PÁGINA INICIAL UTILIZANDO POST
@PostMapping
public String salvar(PrevTempo previsao) {
    prevservice.salvar(previsao);
    return "redirect:/index";
}
}
