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：

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;
}

  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。
