用淘宝接口：(源码：java 根据IP地址获取地理位置)

e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {

connection.disconnect();
}
}

}
}
测试：
@Test
public void getAddressByIp() throws Exception {
// 参数ip
String ip = "219.136.134.157";
// json_result用于接收返回的json数据
String json_result = null;
try {
json_result = AddressUtils.getAddresses("ip=" + ip, "utf-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
JSONObject json = JSONObject.fromObject(json_result);
System.out.println("json数据： " + json);
String country = JSONObject.fromObject(json.get("data")).get("country").toString();
String region = JSONObject.fromObject(json.get("data")).get("region").toString();
String city = JSONObject.fromObject(json.get("data")).get("city").toString();
String county = JSONObject.fromObject(json.get("data")).get("county").toString();
String isp = JSONObject.fromObject(json.get("data")).get("isp").toString();
String area = JSONObject.fromObject(json.get("data")).get("area").toString();
System.out.println("国家： " + country);
System.out.println("地区： " + area);
System.out.println("省份: " + region);
System.out.println("城市： " + city);
System.out.println("区/县： " + county);
System.out.println("互联网服务提供商： " + isp);
String address = country + "/";
address += region + "/";
address += city + "/";
address += county;
System.out.println(address);
结果：
{"code":0,"data":{"country":"中国","country_id":"CN","area":"华南","area_id":"800000","region":"广东省","region_id":"440000","city":"广州市","city_id":"440100","county":"越秀区","county_id":"440104","isp":"电信","isp_id":"100017","ip":"219.136.134.157"}}
国家： 中国
地区： 华南
省份: 广东省
城市： 广州市
区/县： 越秀区
互联网服务提供商： 电信
中国/广东省/广州市/越秀区
但用淘宝的API时，真的很慢，少量数据还可以，一旦数据上万，那就结束不了了，等了好久都运行不完。
没办法，开始尝试其他方法。
用【GeoLite2 City】库（源自：Java 通过Request请求获取IP地址对应省份、城市）
pom.xml:
<dependency>
<groupId>com.maxmind.geoip2</groupId>
<artifactId>geoip2</artifactId>
<version>2.8.1</version>
</dependency>
测试：
public static void main(String[] args) throws IOException{
// 创建 GeoLite2 数据库
File database = new File("/Users/admin/GeoLite2-City.mmdb");
// 读取数据库内容
DatabaseReader reader = new DatabaseReader.Builder(database).build();
InetAddress ipAddress = InetAddress.getByName("171.108.233.157");
// 获取查询结果
CityResponse response = null;
try {
response = reader.city(ipAddress);
// 获取国家信息
Country country = response.getCountry();
System.out.println(country.getIsoCode()); // ‘CN‘
System.out.println(country.getName()); // ‘China‘
System.out.println(country.getNames().get("zh-CN")); // ‘中国‘
// 获取省份
Subdivision subdivision = response.getMostSpecificSubdivision();
System.out.println(subdivision.getName()); // ‘Guangxi Zhuangzu Zizhiqu‘
System.out.println(subdivision.getIsoCode()); // ‘45‘
System.out.println(subdivision.getNames().get("zh-CN")); // ‘广西壮族自治区‘
// 获取城市
City city = response.getCity();
System.out.println(city.getName()); // ‘Nanning‘
Postal postal = response.getPostal();
System.out.println(postal.getCode()); // ‘null‘
System.out.println(city.getNames().get("zh-CN")); // ‘南宁‘
Location location = response.getLocation();
System.out.println(location.getLatitude()); // 22.8167
System.out.println(location.getLongitude()); // 108.3167
} catch (GeoIp2Exception e) {
e.printStackTrace();
}
}
这个就很快了，不过只能获取到城市。
