根据地名获取经纬度

pom.xml   --->添加-maven 依赖包《必须要》

直接上代码，可用

public  String loadJSON(String url) {

    StringBuilder json = new StringBuilder();
    try {
        LOGGER.info("11-2");
        URL oracle = new URL(url);
        URLConnection yc = oracle.openConnection();
        BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream(), "UTF-8"));
        String inputLine = null;
        while ((inputLine = in.readLine()) != null) {
            json.append(inputLine);
        }
        in.close();
    } catch (MalformedURLException e) {} catch (IOException e) {}
    return json.toString();
}


//返回值
@GetMapping("/getCoordinate")
public BaseResponse  getCoordinate(String address) {
    BaseResponse response = new BaseResponse();
    LOGGER.info("1");
    try{
        LOGGER.info("2");
        if (address != null && !"".equals(address)) {
            LOGGER.info("3");
            address = address.replaceAll("\s*", "").replace("#", "栋");
            String url = "http://api.map.baidu.com/geocoder/v2/?address=" + address + "&output=json&ak=F454f8a5efe5e577997931cc01de3974";
            String json = loadJSON(url);
            if (json != null && !"".equals(json)) {
                JSONObject obj = JSONObject.parseObject(json);
                if ("0".equals(obj.getString("status"))) {
                    double lng = obj.getJSONObject("result").getJSONObject("location").getDouble("lng"); // 经度
                    double lat = obj.getJSONObject("result").getJSONObject("location").getDouble("lat"); // 纬度
                    DecimalFormat df = new DecimalFormat("#.######");
                    String lng1 = df.format(lng);
                    String lat1 = df.format(lat);
                    response.setData("经度："+lng1+"纬度："+lat1);
                    response.setSuccess(true);
                    return response;
                }
            }
        }

    }catch (Exception e){
        response.setErrorMsg(ErrorCode.SYSTEM_ERROR.getDesc());
    }
    return response;
}
