netty 发送 超过 1024 数据

开源代码：

https://github.com/anglesun/netty-LengthFieldBasedFrameDecoder

下面的客户端和服务器端是可以的：

客户端：

https://github.com/smartbooks/netty-example/blob/db2a2af757c20707adc60e7500a3d905202e4c58/src/main/java/com/ljja/client/ClientApp.java

服务器端：

https://github.com/smartbooks/netty-example/blob/db2a2af757c20707adc60e7500a3d905202e4c58/src/main/java/com/ljja/server/ServerApp.java

自定义 decode 采用 LengthFieldBasedFrameDecoder

但是和c#通信报错了：

                AbstractUnpooledSlicedByteBuffer buf = (AbstractUnpooledSlicedByteBuffer)message;

               byte  type = buf.ReadByte();
              byte  flag = buf.ReadByte();
              int  length = buf.ReadInt();

c#代码：

https://github.com/jinyuttt/dotnetty/blob/e01dfc50fa1f384a67e726ce9b1dfea737eca796/DotNetty.Buffers/UnpooledSlicedByteBuffer.cs

客户端

Bootstrap b = new Bootstrap();
            b.group(bossGroup)
                    .channel(NioSocketChannel.class)
                    .handler(new LoggingHandler(LogLevel.INFO))
                    .handler(new ChannelInitializer<SocketChannel>() {
                        @Override
                        public void initChannel(SocketChannel ch) throws Exception {
                            ch.pipeline().addLast("ServerDecoder", new ClientDecoder());
                        }
                    })
                    .option(ChannelOption.SO_KEEPALIVE, true)
               .option(ChannelOption.RCVBUF_ALLOCATOR, new FixedRecvByteBufAllocator(65535));

          .option(ChannelOption.RCVBUF_ALLOCATOR, new FixedRecvByteBufAllocator(65535)); ！！！ 这句话是 关键
