java - 使用 java API 进行地理编码

Question

我正在使用Nominatim java api for nomitim 来获取给定地址的经度和纬度属性:https://github.com/AtlisInc/Nominatim-API 。对于每个不同的输入，经度和纬度输出都是相同的。纬度 = 51.3258094，经度 = 11.3400106。我究竟做错了什么？这是代码:

public class Geocoding(){
private volatile NominatimAPI nominatimAPI;//Use Volatile
public NominatimAPI getNominatimAPI(){
NominatimAPI result=nominatimAPI;
if(result==null){
    synchronized (this){//Synchronize for thread safety
        result=nominatimAPI;
        if (result==null){
            result=new NominatimAPI();
            nominatimAPI=result;
        }
    }
}
return result;
}

private static void mymethod2() {
    List<String> cities = Arrays.asList("Los Angeles","Berlin");
    String endpointUrl = "https://nominatim.openstreetmap.org/";
    MapPoint mapPoint;
    Geocoding test=new Geocoding();
    for (String city : cities) {
        NominatimAPI nominatim = test.getNominatimAPI();
        Address address = new Address();
        address.setCity(city);
        nominatim.initNominatimAPI(endpointUrl);
        mapPoint = nominatim.getMapPointFromAddress(address, 18);
       System.out.println(mapPoint.getLatitude()+","+mapPoint.getLongitude());
}
}
}

Answer 1

我没有使用address.setCity(city);，而是使用address.setCountry(city)。对于每个引用地址的输入，您可以与setCountry一起使用。它返回真实的经度和纬度值。我不明白为什么只有setCountry有效，但它确实有效。
