windows或linux系统下获取多网卡的ip地址

 在windows或者linux操作系统中，获取多网卡信息，可通过执行命令方式获取，具体如下：

 

public Vector<String> getServerIps()
   {
       Vector<String> address = new Vector<String>();
       String linuxKey = "inet";
       String window7Key = "IPv4";
       String windowKey = "IP Address";
       String os = System.getProperty("os.name");
       if (os != null)
       {
           if (os.startsWith("Windows"))
           {
               try
               {
                   ProcessBuilder pb = new ProcessBuilder("ipconfig", "/all");
                   Process p = pb.start();
                   BufferedReader br = new BufferedReader(
                       new InputStreamReader(p.getInputStream()));
                   String line;
                   while ((line = br.readLine()) != null)
                   {
                       if ((line.indexOf(window7Key) != -1)
                           || (line.indexOf(windowKey) != -1))
                       {
                           int index = line.indexOf(":");
                           int indexLast = line.indexOf("(");
                           String sbstr = null;
                           if (indexLast == -1)
                           {
                               sbstr = line.substring(index + 1).trim();

                           }

                           {
                               sbstr = line.substring(index + 1, indexLast).trim();

                           }
                           if (!sbstr.equals("127.0.0.1"))
                           {
                               address.add(sbstr);
                           }
                       }
                   }
