关于Netty发送数据的问题

[痴傻二呆萌]

先上代码:
服务端:

public class Server {

	static int port = 8787;

	public static void main(String[] args) throws Exception {
		EventLoopGroup bossGroup = new NioEventLoopGroup();
		EventLoopGroup workerGroup = new NioEventLoopGroup();
		try {
			ServerBootstrap b = new ServerBootstrap();
			b.group(bossGroup, workerGroup).channel(NioServerSocketChannel.class)
					.childHandler(new ChannelInitializer<SocketChannel>() {
						@Override
						public void initChannel(SocketChannel ch) throws Exception {
							ch.pipeline().addLast(new ProtobufVarint32FrameDecoder());
							ch.pipeline().addLast(new ProtobufDecoder(CallMessage.getDefaultInstance()));
							ch.pipeline().addLast(new ProtobufServerHandler());
						}
					}).option(ChannelOption.SO_BACKLOG, 128).childOption(ChannelOption.SO_KEEPALIVE, true);

			// 服务器绑定端口监听
			ChannelFuture f = b.bind(port).sync();
			// 监听服务器关闭监听
			f.channel().closeFuture().sync();
		} finally {
			bossGroup.shutdownGracefully();
			workerGroup.shutdownGracefully();
		}
	}
}


@Sharable
public class ProtobufServerHandler extends ChannelInboundHandlerAdapter {
	int i = 0;

	@Override
	public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
		if (msg instanceof CallMessage) {
			CallMessage message = (CallMessage) msg;
			System.out.println(message.getContent());
			i++;
		}
	}

	@Override
	public void channelUnregistered(ChannelHandlerContext ctx) throws Exception {
		ctx.fireChannelUnregistered();
		System.out.println("断开连接->" + i);
	}

}

客户端:

public class Client {
	static int port = 8787;
	static String host = "127.0.0.1";

	public static void main(String[] args) throws InterruptedException, IOException {
		EventLoopGroup group = new NioEventLoopGroup();
		try {
			Bootstrap b = new Bootstrap();
			b.group(group).channel(NioSocketChannel.class);
			b.option(ChannelOption.SO_KEEPALIVE, true);
			b.handler(new ChannelInitializer<SocketChannel>() {
				@Override
				public void initChannel(SocketChannel ch) throws Exception {
					// 编码
					ch.pipeline().addLast(new ObjectEncoder());
					ch.pipeline().addLast("frameEncoder", new ProtobufVarint32LengthFieldPrepender());
					ch.pipeline().addLast("protobufEncoder", new ProtobufEncoder());
				}
			});

			// 连接服务端
			Channel ch = b.connect(host, port).sync().channel();

			long start = System.currentTimeMillis();
			for (int i = 0; i < 100; i++) {
				Message m = Message.newBuilder().setContent("random" + RandomUtils.nextInt(1, 10000)).build();
				ch.writeAndFlush(m);
			}
			long end = System.currentTimeMillis();
			System.out.println(end - start + "ms");
		} finally {
			group.shutdownGracefully();
		}
	}
}

现在是从Client向Server发送数据时,打印出来就接收到64条数据.
如果在发送时停一下,加个Thread.sleep(1); 就能全部接收到了.
不明白这是为什么,如果不加sleep想要接收全部数据 应该怎么做.
谢谢各位

如果发送包大，加 sleep延时，数据能全部接收到这也正常吧

[晚起的笨鸟]

是不是粘包了，不可能只有64条，你打印点固定的内容比如“abc“这样的就知道了

sleep 3000 延迟处理？
