JAVA服务器端获取客户端远程地址，根据IP获取远程地址，各IP地址查询接口比较

废话少说，先整代码：

一、根据远程请求，获取远程IP

代码整完了，问题也解决了……

说明一下，

我最开始获取客户端地址，用的是在前端页面引入“http://ip.ws.126.net/ipquery”接口，

但此接口只支持js，无法写到Java后台去，

项目从http转https后该接口边便失效，又找不到https协议的ip查询接口，

因此只能在后台获取远程ip（LSB的话记得ip转换），便开始在后台使用淘宝的ip地址查询接口，

可是高频率访问时淘宝ip地址查询接口总是SocketTimeout，经过各种Httpclient优化无效，后来发现加上时间戳去缓存可以改善连接超时，

就这样用了一段时间后，频繁访问时还是会报SocketTimeoutException,

因此又调研了这许多接口，最终确定了三个比较高效、精确、稳定的接口，做成了多线程的方式随机访问。
