public class ByteArrayDecoder extends MessageToMessageDecoder<ByteBuf>
ByteBuf解码为字节数组。
TCP / IP的典型设置是：
ChannelPipeline pipeline = ...;
// Decoders
pipeline.addLast("frameDecoder",
new LengthFieldBasedFrameDecoder(1048576, 0, 4, 0, 4));
pipeline.addLast("bytesDecoder",
new ByteArrayDecoder());
// Encoder
pipeline.addLast("frameEncoder", new LengthFieldPrepender(4));
pipeline.addLast("bytesEncoder", new ByteArrayEncoder());
然后您可以使用一个字节数组而不是ByteBuf作为消息：
void channelRead(ChannelHandlerContext ctx, byte[] bytes) {
...
}

ctx - MessageToMessageDecoder属于的ChannelHandlerContext
msg - 解码到另一个的消息
out - 应该添加解码消息的
List
java.lang.Exception - 发生错误时抛出
