java获取请求的ip地址，并解析ip所属地区

每次看见QQ上面能够显示对方的ip和地址让人觉得舒服。。刚刚无聊就上网逛了下如何使用java实现获取对方ip和所属地址，找到了些资料，整理成一个工具包供大家使用： 首先是如何获取对方的ip地址，方法很简单，如下： Java代码 1. public String getIpAddr(HttpServletRequest request) { 2. String ip = request.getHeader("x-forwarded-for"); 3. if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 4. ip = request.getHeader("Proxy-Client-IP"); 5. } 6. if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 7. ip = request.getHeader("WL-Proxy-Client-IP"); 8. } 9. if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 10. ip = request.getRemoteAddr(); 11. } 12. return ip; 13. } public String getIpAddr(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; } 然后得到了ip是不是很想知道对方在哪里呢，嘿嘿，没问题。使用纯真ip库 下载地址，及使用方法我已经打包上传，里面包括纯真ip库文件，使用该库的工具包，和使用说明。 希望对你有帮助。
