1.在会话中获得远程IP和端口

@Override

public void messageReceived(IoSession session, Object message) throws Exception {
   InetSocketAddress remoteAddress = (InetSocketAddress) session.getRemoteAddress();
   System.out.println(remoteAddress.getAddress().getHostAddress()+" "+ remoteAddress.getPort());

}

2.在会话中获得本地IP和端口

@Override

public void messageReceived(IoSession session, Object message) throws Exception {
   InetSocketAddress localAddress = (InetSocketAddress) session.getLocalAddress();
   System.out.println(localAddress.getAddress().getHostAddress()+" "+ localAddress.getPort());

}
