#### 1.获取计算机地址 ####

public String getAddress() {
        
            try {
        
                InetAddress address = InetAddress.getLocalHost();
                return address.getHostAddress();
            } catch (UnknownHostException e) {
        
                // 异常或无权访问设置为 127.0.0.1
                e.printStackTrace();
                return "127.0.0.1";
            }
        }

#### 2.获取计算机名称 ####

public String getHostName() {
        
            try {
        
                InetAddress address = InetAddress.getLocalHost();
                return address.getHostName();
            } catch (UnknownHostException e) {
        
                // 异常或无权访问设置为 localhost
                e.printStackTrace();
                return "localhost";
            }
        }

#### 3.获取计算机MAC地址 ####

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