废话少说，先整代码：

一、根据远程请求，获取远程IP

/** * Copyright (c) 2016,sunnybs.  * All Rights Reserved. *  * Project Name:sunego-commerce-common * Package Name:com.sunego.commerce.common.http * File Name:IPUtils.java * Date:2016年4月28日 上午11:23:53 *  */package com.sunego.commerce.common.http;import javax.servlet.http.HttpServletRequest;/** * ClassName: IPUtils <br/> * Description: IP查询工具 <br/> * Date: 2016年4月28日 上午11:23:53 <br/> * <br/> *  * @author Administrator(邮箱) *  *         修改记录 * @version 产品版本信息 yyyy-mm-dd 姓名(邮箱) 修改信息<br/> *  */public class IPUtils {    public static Address address;    /**     *      * getRemoteIP:获取远程请求客户端的外网IP <br/>     *      * @param request     *            请求实体对象     * @return ip 外网ip<br/>     */    public static String getRemoteIP(HttpServletRequest request) {        String ip = request.getHeader("x-forwarded-for");        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getHeader("Proxy-Client-IP");        }        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getHeader("WL-Proxy-Client-IP");        }        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getRemoteAddr();        }        return ip;    }    /**     *      * getAddresses:根据外网ip，判断该ip所在的地理位置 <br/>     *      * @param ip     *            外网ip     * @return 该ip所在的地理位置 <br/>     */    public static String getAddresses(String ip) {        return Address.getSingleInstance().getAddresses(ip);    }}

二、根据远程IP，获取远程物理地址

   private static Address address;    /**     * 单例模式     */    public static Address getSingleInstance() {        if (null == address) {            // 懒加载            synchronized (Address.class) {                if (null == address) {                    address = new Address();                }            }        }        return address;    }    /**     * 根据远程ip，查询对应的物理地址<br/>     * 只返回所查询到的地址的最后一级，例如address="北京市海淀区西二旗"，则返回"西二旗"<br/>     * 使用太平洋、淘宝、百度三个ip地址查询接口，多进程异步查询<br/>     */    public String getAddresses(String ip) {        // 清除上次查询结果        ipAddressMap.remove(ip);

三、测试用例

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。
