1.获取计算机地址

  1. public String getAddress() {
  3.         try {
  5.             InetAddress address = InetAddress.getLocalHost();
  6.             return address.getHostAddress();
  7.         } catch (UnknownHostException e) {
  9.             // 异常或无权访问设置为 127.0.0.1
  10.             e.printStackTrace();
  11.             return "127.0.0.1";
  12.         }
  13.     }

2.获取计算机名称

  1. public String getHostName() {
  3.         try {
  5.             InetAddress address = InetAddress.getLocalHost();
  6.             return address.getHostName();
  7.         } catch (UnknownHostException e) {
  9.             // 异常或无权访问设置为 localhost
  10.             e.printStackTrace();
  11.             return "localhost";
  12.         }
  13.     }

3.获取计算机MAC地址

  1. public static String getMac() {
  3.         try {
  5.             InetAddress inetAddress = InetAddress.getLocalHost();
  6.             byte[] mac = NetworkInterface.getByInetAddress(inetAddress).getHardwareAddress();
  7.             StringBuilder sb = new StringBuilder();
  8.             for (int i = 0; i < mac.length; i ++) {
  10.                 sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : "\n"));
  11.             }
  12.             return sb.toString();
  13.         } catch (UnknownHostException | SocketException e) {
  15.             // 异常或无权访问设置为 localhost
  16.             e.printStackTrace();
  17.             return "00-00-00-00-00-00";
