在桌面应用程序中使用RestTemplate消费Rest Service时出现的问题

尝试改用数组：

String url = "http://localhost:8080/mgm/country";List<MediaType> mediaTypes = new ArrayList<MediaType>();mediaTypes.add(MediaType.APPLICATION_JSON);HttpHeaders headers = new HttpHeaders();headers.setAccept(mediaTypes);HttpEntity<Country> httpEntity = new HttpEntity<Country>(null, headers);try {    ResponseEntity<Country[]> responseEntity = restTemplate.exchange(url, HttpMethod.GET, httpEntity, Country[].class);    Country[] countries = responseEntity.getBody();    System.out.println(countries[0].getName());} catch (RestClientException exception) {    exception.printStackTrace();}
