1、传入HttpServletRequest

通过IP获取准确地址，精确到县/区_java

2、通过HttpServletRequest获取IP

public static String getIpAddress(HttpServletRequest request) {
        if (request.getHeader("x-forwarded-for") == null) {
            return request.getRemoteAddr();
        }
        return request.getHeader("x-forwarded-for");
    }

3、通过IP获取具体位置

/**
     * 获取ip对应地址地址(比百度地图精准，还不用ak之类的秘钥)
     * @param ip ip
     * @return
     */
    public static String getAddressPlus(String ip){
        if(ip.contains("127.0.0.1") || ip.contains("0:0:0:0:0:0:0:1")){
            return "本地";
        }
        //更精确的地图API
        String url = "https://sp1.baidu.com/8aQDcjqpAAV3otqbppnN2DJv/api.php?query="+ ip +"&resource_id=5809";
        String body = postToBaidu(ip,url);
        JSONObject jsonObject = JSON.parseObject(body);
        JSONArray data1 = jsonObject.getJSONArray("data");
        JSONObject o = (JSONObject)data1.get(0);
        return o.getString("location");

    }

4、具体效果

通过IP获取准确地址，精确到县/区_tcp/ip_02
