public static String getPhysicalAddress() {
    Process p = null;

    try {
        // 执行ipconfig /all命令
        p = new ProcessBuilder("ipconfig", "/all").start();
    } catch (IOException e) {
        return "";
    }
    byte[] b = new byte[1024];
    int readbytes = -1;
    StringBuffer sb = new StringBuffer();
    // 读取进程输出值
    InputStream in = p.getInputStream();
    try {
        while ((readbytes = in.read(b)) != -1) {
            sb.append(new String(b, 0, readbytes));
        }

    } catch (IOException e1) {
    } finally {
        try {
            in.close();
