Question

netty websocket 有没有粘包问题

Answer 1

客户端发送消息
String message = "netty is a nio server framework &"
+"which enables quick and easy development &"
+"of net applications such as protocol &"
+"servers and clients!";

服务端添加解码器：DelimiterBasedFrameDecoder
ByteBuf delimiter = Unpooled.copiedBuffer("&".getBytes());
ch.pipeline().addLast(new DelimiterBasedFrameDecoder(1024,delimiter));
//1024表示单条消息的最大长度，解码器在查找分隔符的时候，达到该长度还没找到的话会抛异常
ch.pipeline().addLast(new StringDecoder());
....
ch.pipeline().addLast(new StringEncoder());
