服务器IP：

String addr = InetAddress.getLocalHost().getHostAddress();

说明：很明显上面是没考虑到服务器有多个iP的情况。

客户顿啊IP：

　　/**
     * 获取IP
     *
     * @param request HttpServletRequest
     * @return IP字符串
     */
    public static String getRemoteHost(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 "0:0:0:0:0:0:0:1".equals(ip) ? "127.0.0.1" : ip;
    }
