컨트롤러 수정

컨트롤러에서 HTML 페이지 반환하게끔 수정

src/main/java/com/example/demo/controller

[추가할 메소드 부분]

package com.example.demo.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import java.util.List;
import com.example.demo.entity.TouristSpot;
import com.example.demo.service.TouristSpotService;

@Controller
public class TouristSpotController {

    @Autowired
    private TouristSpotService touristSpotService;

    @GetMapping("/touristspots")
    public String getAllTouristSpots(Model model) {
        List<TouristSpot> touristSpots = touristSpotService.findAll();
        model.addAttribute("touristSpots", touristSpots);
        return "index"; // index.html 템플릿을 반환
    }
}

새로운 컨트롤러 (TouristSpotHtmlController):

• 새로운 컨트롤러를 추가하여 HTML 템플릿을 제공
• @Controller와 /touristspots 경로를 사용하여 HTML 페이지를 제공
• getAllTouristSpots 메서드는 Model 객체를 사용하여 touristSpots 데이터를 HTML 템플릿에 전달

 

[기존 메소드]

@Autowired
private TouristSpotService touristSpotService;

@GetMapping
public List<TouristSpot> getAllTouristSpots() {
    return touristSpotService.findAll();
}

@GetMapping("/{id}")
public TouristSpot getTouristSpotById(@PathVariable Long id) {
    return touristSpotService.findById(id);
}

@PostMapping
public TouristSpot createTouristSpot(@RequestBody TouristSpot touristSpot) {
    return touristSpotService.save(touristSpot);
}

@PutMapping("/{id}")
public TouristSpot updateTouristSpot(@PathVariable Long id, @RequestBody TouristSpot touristSpot) {
    TouristSpot existingSpot = touristSpotService.findById(id);
    if (existingSpot != null) {
        existingSpot.setName(touristSpot.getName());
        existingSpot.setDescription(touristSpot.getDescription());
        return touristSpotService.save(existingSpot);
    } else {
        return null;
    }
}

@DeleteMapping("/{id}")
public void deleteTouristSpot(@PathVariable Long id) {
    touristSpotService.deleteById(id);
}

기존 컨트롤러 (TouristSpotController):

• 기존의 RESTful API 엔드포인트를 유지
• @RestController와 /api/touristspots 경로를 사용하여 JSON 데이터를 제공
