今天在代码中遇到了Java获取本机IP的需求，网上搜了好多，决定记录下来，方便以后使用。

/** * 获取本机IP 方法一 * 传递request 对象进来 * @param request * @return */public static String getRemortIP(HttpServletRequest request) {   if (request.getHeader("x-forwarded-for") == null) {    return request.getRemoteAddr();   }   return request.getHeader("x-forwarded-for");  }

<pre name="code" class="java">/** * 获取本机IP 方法二 * 传递request 对象进来 * @param request * @return */public static String getRemortIP(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;    }
