这是我从地理编码器获得响应的代码：
public class Snippet {
private GeoCodeResponse getAddressFromLatLng(double lattitute,
double longtitute) throws ClientProtocolException, IOException {
String latitude = String.valueOf(lattitute);
String longitude = String.valueOf(longtitute);
String URL = "http://maps.google.com/maps/api/geocode/json?latlng="
+ latitude + "," + longitude + "&sensor=true";
RestTemplate restTemplate = new RestTemplate();
ObjectMapper mapper = new ObjectMapper();
String forObject = restTemplate.getForObject(URL, String.class);
GeoCodeResponse geoCodeResponse = mapper.readValue(forObject,
GeoCodeResponse.class);
System.out.println(forObject);
return geoCodeResponse;
}
public static void main(String[] args) throws ClientProtocolException,
IOException {
GeoCodeResponse geoCoderResponse = new TrackServiceImpl()
.getAddressFromLatLng(17.42560, 78.548339);
if (geoCoderResponse.getStatus().equals("OK")) {
List<Results> listOfResults = geoCoderResponse.getResults();
for (Results result : listOfResults) {
// get Results Object
Iterator<Results> results = listOfResults.iterator();
while (results.hasNext()) {
result = results.next();
System.out.println(result.getFormatted_address());
// get Address Object
Collection<AddressComponent> addresscomponents = result
.getAddress_components();
Iterator<AddressComponent> addresscomponentsIterator = addresscomponents
.iterator();
while (addresscomponentsIterator.hasNext()) {
AddressComponent addressComponent = addresscomponentsIterator
.next();
System.out.println(addressComponent.getLong_name());
System.out.println(addressComponent.getShort_name());
}
// get Geometry Object
Geometry geometry = result.getGeometry();
System.out.println(geometry.getLocation_type());
// get Location Object
Location location = geometry.getLocation();
System.out.println(location.getLat());
System.out.println(location.getLng());
}
break;
}
}
}
private GeoCodeResponse getAddressFromLatLng(double lattitute,
double longtitute) throws ClientProtocolException, IOException {
String latitude = String.valueOf(lattitute);
String longitude = String.valueOf(longtitute);
String URL = "http://maps.google.com/maps/api/geocode/json?latlng="
+ latitude + "," + longitude + "&sensor=true";
RestTemplate restTemplate = new RestTemplate();
ObjectMapper mapper = new ObjectMapper();
String forObject = restTemplate.getForObject(URL, String.class);

return geoCodeResponse;
}
}
这是地理编码器的响应：

我的问题是如何从下面的对象中获取这些？

请帮助我，我无法获得这个格式化的地址。提前致谢。
