    public class Distance {
         public static void main(String[] args) {
            //1、通过java api从高德地图获取经纬度
            String url = "http://restapi.amap.com/v3/geocode/geo?address=上海市东方明珠&output=JSON&key=xxxxxxxxx";
    
            AsyncHttpClientConfig.Builder builder = new AsyncHttpClientConfig.Builder();
            builder.setCompressionEnabled(true).setAllowPoolingConnection(true);
            builder.setRequestTimeoutInMs((int) TimeUnit.MINUTES.toMillis(1));

            AsyncHttpClient client = new AsyncHttpClient(builder.build());
            try {
                ListenableFuture<Response> future = client.prepareGet(url).execute();
                String result = future.get().getResponseBody();

                    System.out.println(listSource);
                    for(String location : listSource.textValue().split(",")){
                        //得到这个位置的经纬度
                        System.out.println(location);
                        //System.out.println(Double.valueOf(location));
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                if(client != null){
                    client.close();
                }
            }
        }
