Java后端利用百度地图全球逆地理编码，获取地址

声明：本人是在实习项目的时候遇到的问题

一.使用Api分为四步骤全球逆地理编码 rgc 反geo检索 | 百度地图API SDK

步骤1,2自行完成接下来去获取AK

二.申请AK

登录百度账号

点击创建应用，选择自己想用的服务，我只单选了逆地理编码，默认全选也是可以。

ip白名单自行设置，嫌麻烦可以设置为0.0.0.0/0，点击提交后拿到自己的AK

三.编写java代码

@Data
@Component
public class BaiduMapsUtils {

    private static final String API_KEY = "uCrrxBDB4bl76vh9B7F3vYfn3OVujUVd";
    private static final String REVERSE_GEOCODING_URL = "http://api.map.baidu.com/reverse_geocoding/v3/?ak=" + API_KEY + "&location=%s,%s&output=json";

    public static JsonNode reverseGeocode(Double  latitude, Double longitude) throws Exception {
        String urlString = String.format(REVERSE_GEOCODING_URL, latitude, longitude);
        URL url = new URL(urlString);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("GET");
        connection.setRequestProperty("Accept", "application/json");

        if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {
            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String inputLine;
            StringBuilder response = new StringBuilder();

            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();
            connection.disconnect();
            ObjectMapper objectMapper = new ObjectMapper();
            JsonNode jsonNode = objectMapper.readTree(response.toString());

            return jsonNode;
        } else {
             return null;
        }
    }
}

    @RequestMapping("/api/index/positioning")
    public R getPositioning(@RequestParam(value = "longitude") Double longitude,
                            @RequestParam(value = "latitude") Double latitude){
        JsonNode jsonNode = null;
        try{
             jsonNode = BaiduMapsUtils.reverseGeocode(longitude, latitude);
        }catch (Exception e){
            log.error("百度地图接口异常",e);
        }
        return R.data(jsonNode);
    }

简单编写了一段代码，代码不是唯一的，测试正常。
