1.引入Maven
<dependency>
<groupId>org.lionsoul</groupId>
<artifactId>ip2region</artifactId>
<version>2.7.0</version>
</dependency>2.下载ip2region文件
csdn下载: (1条消息) 【免费】ip2region.xdb解压获得资源-CSDN文库
官网下载:ip2region/data at master · lionsoul2014/ip2region · GitHub
3.放入项目
4.IpUtils工具类

* 获取用户真实IP地址，不使用request.getRemoteAddr();的原因是有可能用户使用了代理软件方式避免真实IP地址,
* 参考文章： http://developer.51cto.com/art/201111/305181.htm
* <p>
* 可是，如果通过了多级反向代理的话，X-Forwarded-For的值并不止一个，而是一串IP值，究竟哪个才是真正的用户端的真实IP呢？
* 答案是取X-Forwarded-For中第一个非unknown的有效IP字符串。
* <p>
* 如：X-Forwarded-For：192.168.1.110, 192.168.1.120, 192.168.1.130,
* 192.168.1.100
