为什么Netty不断吐出这个错误？

Question

我有一个游戏，已经在其中编码了一个联网系统。 我有小包之类的.. 但是我的服务器和客户端会不断吐出错误吗？ 我想知道如何解决此问题。

我的客户不断吐痰：

我的服务器不断吐痰：

我的服务器说错误来自此方法的最后一行：

  public static Object encode(final byte[] data) throws IOException, ClassNotFoundException {
        return new ObjectInputStream(new ByteArrayInputStream(data)).readObject();
  }

这是我对数据包进行解码和编码的方式：

 public static byte[] decode(Packet packet) throws IOException {
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        ObjectOutputStream oos = new ObjectOutputStream(bos);
        oos.writeObject(packet);
        oos.flush();
        return bos.toByteArray();
    }

    public static Object encode(final byte[] data) throws IOException, ClassNotFoundException {
        return new ObjectInputStream(new ByteArrayInputStream(data)).readObject();
    }

    public static ByteBuf asByteBuf(Packet packet) throws IOException {
        byte[] arr = decode(packet);
        return Unpooled.copiedBuffer(arr);
    }

我在客户端和服务器端都这样做。 服务器和客户端都在Java版本8上运行！

请有人能解释为什么这个问题发生了，我可能做错了什么吗？

这是我的服务器端channelRead函数：

  @Override
    public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
        final ByteBuf buf = (ByteBuf) msg;
        final int len = buf.readableBytes();
        final byte[] bytes;
        final int offset;
        if (buf.hasArray()) {
            bytes = buf.array();
            offset = buf.arrayOffset();
        } else {
            bytes = new byte[len];
            buf.getBytes(buf.readerIndex(), bytes);
            offset = 0;
        }
        final Packet packet;
        try {
            packet = (Packet) Packet.encode(bytes);
        } catch (Exception ex) {
            ex.printStackTrace();
            return;
        }
        handlePackets(ctx, packet, buf);
    }
