根据IP获取具体城市名称及经纬度坐标

用到两款工具， geoip-api 这个可以根据IP获取城市以及经纬度 但是获取的城市是拼音不是汉字 导致山西和陕西的拼音相同 无法分辨，所以引入第二款工具ip2region 可以根据ip获取到具体的省市IP供应商名称 格式如：中国|0|上海|上海市|联通

1.pom依赖和所需要的数据文件GeoLiteCity-2013-01-18.dat【下载地址 https://dev.maxmind.com/geoip/geoip2/geolite2/】 与 ip2region.db【下载地址https://gitee.com/lionsoul/ip2region/tree/v1.6.1-release】 放到/resources目录下就行了

        
            com.maxmind.geoip
            geoip-api
            1.3.1
        
        
            eu.bitwalker
            UserAgentUtils
            1.21
        
        
        
            org.lionsoul
            ip2region
            1.7
        

2.工具类配置 放下util报下就行  IPUtil.java  GEOIpAndAgentUtils.java

    }


    public static void main(String[] args) throws Exception {
        System.err.println(getCityInfo("220.248.12.158"));
    }
}

package com.****.utils;

    static {
        File file = new File("src/main/resources/GeoLiteCity-2013-01-18.dat");
        System.out.println(file.getAbsolutePath());
        try {
            lookupService = new LookupService(file, LookupService.GEOIP_MEMORY_CACHE);
        } catch (IOException e) {

    }

    public static Map parseLocaltion(String ip) {
        Location location = lookupService.getLocation(ip);
       /* String city = location.city;*/
        HashMap locationMap = new HashMap<>();
        String cityInfo = IPUtil.getCityInfo(ip);
        String[] split = cityInfo.split("\\|");

        locationMap.put("city", split[2]);//只需要获取当前省或者直辖市
        locationMap.put("point", new Float[]{location.longitude, location.latitude});
        return locationMap;
    }

    public static String parseAgentInfo(String agentInfo) {
        UserAgent agent = UserAgent.parseUserAgentString(agentInfo);
        Browser browser = agent.getBrowser();
        return browser.getName() + "|"
                + browser.getBrowserType().getName() + "|"
                + agent.getBrowserVersion().getVersion() + "|"
                + agent.getOperatingSystem().getManufacturer() + "|"
                + agent.getOperatingSystem().getName();
    }
}

3.用法举例：

Map location=GEOIpAndAgentUtils.parseLocaltion（"1.198.72.174"）

String s=new ObjectMapper().writeValueAsString(location)
//s中包含了地理位置的所有信息
