阿尔伯特，我认为您担心的是您的代码无法正常工作。在这里，下面的代码非常适合我。我认为您缺少URIUtil.encodeQuery将字符串转换为 URI。
我正在使用 gson 库，下载它并将其添加到您的路径中。
要获取用于 gson 解析的类，您需要转到jsonschema2pojo。只需在浏览器上触发http://maps.googleapis.com/maps/api/geocode/json?address=Sayaji+Hotel+Near+balewadi+stadium+pune&sensor=true ，获取结果并将其粘贴到此站点上。它会为你生成你的 pojo。您可能还需要添加一个 annotation.jar。
相信我，工作很容易。不要沮丧。
try {
URL url = new URL(
"http://maps.googleapis.com/maps/api/geocode/json?address="
+ URIUtil.encodeQuery("Sayaji Hotel, Near balewadi stadium, pune") + "&sensor=true");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Accept", "application/json");
if (conn.getResponseCode() != 200) {
throw new RuntimeException("Failed : HTTP error code : " + conn.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader((conn.getInputStream())));
String output = "", full = "";
while ((output = br.readLine()) != null) {
System.out.println(output);
full += output;
}
PincodeVerify gson = new Gson().fromJson(full, PincodeVerify.class);
response = new IsPincodeSupportedResponse(new PincodeVerifyConcrete(
gson.getResults().get(0).getFormatted_address(),
gson.getResults().get(0).getGeometry().getLocation().getLat(),
gson.getResults().get(0).getGeometry().getLocation().getLng())) ;
try {
String address = response.getAddress();
Double latitude = response.getLatitude(), longitude = response.getLongitude();
if (address == null || address.length() <= 0) {
log.error("Address is null");
}
} catch (NullPointerException e) {
log.error("Address, latitude on longitude is null");
}
conn.disconnect();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Geocode http 有效，我刚刚解雇了它，结果如下

关于“答案不包含足够的细节”
从所有研究中，您期望谷歌地图可以参考位置、区域、城市的每一种组合。但事实仍然是谷歌地图在其自身的上下文中包含地理和反向地理。你不能指望它有一个像Sayaji Hotel, Near balewadi stadium, pune. Web google maps 会为您找到它，因为它使用更广泛的Search丰富的 google 后端。google api 的唯一反向地理地址是从他们自己的 api 接收的。对我来说，这似乎是一种合理的工作方式，考虑到我们的印度地址系统有多复杂，第二个十字路口可能离第一个十字路口很远:)
