springboot获取ip地址

Java获取调用接口的ip地址

public static String getIpAddr(HttpServletRequest request) {
     
        String ipAddress = null;
        try {
     
            ipAddress = request.getHeader("x-forwarded-for");
            if (ipAddress == null || ipAddress.length() == 0
                    || "unknown".equalsIgnoreCase(ipAddress)) {
     
                ipAddress = request.getHeader("Proxy-Client-IP");
            }
            if (ipAddress == null || ipAddress.length() == 0
                    || "unknown".equalsIgnoreCase(ipAddress)) {
     
                ipAddress = request.getHeader("WL-Proxy-Client-IP");
            }
            if (ipAddress == null || ipAddress.length() == 0
                    || "unknown".equalsIgnoreCase(ipAddress)) {
     
                ipAddress = request.getRemoteAddr();
                if (ipAddress.equals("127.0.0.1")) {
     
                    // 根据网卡取本机配置的IP
                    InetAddress inet = null;
                    try {
     
                        inet = InetAddress.getLocalHost();
                    } catch (UnknownHostException e) {
     
                        e.printStackTrace();
                    }
                    ipAddress = inet.getHostAddress();
                }
            }
            // 对于通过多个代理的情况，第一个IP为客户端真实IP,多个IP按照','分割
            if (ipAddress != null && ipAddress.length() > 15) {
      // "***.***.***.***".length()
                                                                // = 15
                if (ipAddress.indexOf(",") > 0) {
     
                    ipAddress = ipAddress.substring(0, ipAddress.indexOf(","));
                }
            }
        } catch (Exception e) {
     
            ipAddress = "";
        }
        // ipAddress = this.getRequest().getRemoteAddr();

        return ipAddress;
    }
