 request.getHeader("User-Agent");    //就是取得客户端的系统版本     

  request.getRemoteAddr();    //取得客户端的IP     

  request.getRemoteHost();    //取得客户端的主机名     

  request.getRemotePort();    //取得客户端的端口     

  request.getRemoteUser();    //取得客户端的用户     

  request.getLocalAddr();    //取得本地IP     

  request.getLocalPort();    //取得本地端口

InetAddress inet = InetAddress.getLocalHost();

  System.out.println("本机的ip=" + inet.getHostAddress());
