我制作了一个使用第三方 API 的程序：我有一个名为：NewsService 的服务

@Service
public class NewsService {
    @Autowired
    private NewsRepository newsRepository;
    public List<News> getTopStories() throws Exception{
        RestTemplate restTemplate = new RestTemplate();
        JSONObject news = new JSONObject();
        NewsStories newsentity = new NewsStories();
        List<News> stories = new ArrayList<News>();
        ObjectMapper mapper = new ObjectMapper();
        String getUrl = "https://api.nytimes.com/svc/topstories/v2/home.json?api-key=84e19f8ee1c7489a97481d2ed85af15c";
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        HttpEntity<Map> entity = new HttpEntity<Map>(headers);
        ResponseEntity<Map> newsList = restTemplate.exchange(getUrl, HttpMethod.GET, entity, Map.class);
        if (newsList.getStatusCode() == HttpStatus.OK) {
            news = new JSONObject(newsList.getBody());
            newsentity = mapper.readValue(news.toString(),NewsStories.class);
            newsentity.getStories().forEach(stories::add);
        }
        return …
