Question

Netty怎样增大缓冲区

Answer 1

有现成的方法，你说的那种限制还根本没涉及到粘包解码的问题，而是netty底层限制了接收字节缓存区大小为1024，下面这样就行了
bootstrap.group(bossGroup, workerGroup)
.channel(NioServerSocketChannel.class)
.childOption(ChannelOption.RCVBUF_ALLOCATOR, new AdaptiveRecvByteBufAllocator(64, 1024, 65536))
.childHandler(new ChannelInitializer<SocketChannel>() {
@Override
public void initChannel(SocketChannel ch) throws Exception {
ch.pipeline().addLast(new IdleStateHandler(10, 10, 0));
ch.pipeline().addLast(new HeartBeat());
ch.pipeline().addLast(new ByteStreamDecoder());
ch.pipeline().addLast(new ByteStreamEncoder());
ch.pipeline().addLast(new ServerStreamHandler());
}
});
