Netty UDP DatagramPacket反序列化？

Question

在服务器中使用proto UDP发送POJO可序列化，但在客户端如何使用netty反序列化UDP DatagramPacket？

Answer 1

只需扩展此处理程序

abstract public class BaseChannelInboundHandler<D> extends SimpleChannelInboundHandler<DatagramPacket> {

@Override
protected void channelRead0(ChannelHandlerContext ctx, DatagramPacket datagramPacket) throws Exception {
    try {
        ByteBuf buf = datagramPacket.content();
        byte[] bytes = new byte[buf.readableBytes()];
        buf.readBytes(bytes);
        ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes);
        ObjectInputStream inputStream = new ObjectInputStream(byteArrayInputStream);
        Object obj = inputStream.readObject();
        @SuppressWarnings("unchecked")
        D d = (D) obj;
        messageReceived(ctx, d);
    } catch (Exception e) {
        FLog.e(e);
    }
}

abstract protected void messageReceived(ChannelHandlerContext ctx, D data);

}
