java - 如何将字节 [] 写入 IoSession

Question

如下所示，我可以在没有协议解码器的情况下读取从 IoSession 发送的 byte[]。

IoBuffer in = (IoBuffer) message;
byte[] inBytes = in.array();
int length = inBytes[0];
inBytes = Arrays.copyOfRange(inBytes, 1, length + 1);
ByteString incomingMessage = ByteString.copyFrom(inBytes);

但是当我尝试这样做时：

someIoSession.write(incomingMessage.toByteArray());

我收到以下错误。

Don't know how to handle message of type XXXX. Are you missing a protocol encoder?

我怎样才能将字节写入 IoSession？

Answer 1

someIoSession.write(IoBuffer.wrap(incomingMessage.toByteArray()));
