springboot netty tcp 黏包拆包消息不全

服务端接收消息解析老是出现消息不全的问题

解码编码器

@Component
public class SimpleChatChannelInitializer extends ChannelInitializer {
    @Override
    protected void initChannel(SocketChannel socketChannel) {
        ChannelPipeline pipeline = socketChannel.pipeline();
        ByteBuf bufAck = Unpooled.copiedBuffer("".getBytes());
        ByteBuf bufReply = Unpooled.copiedBuffer("".getBytes());
        pipeline.addLast(new DelimiterbasedframeDecoder(5 * 1024 * 1024,bufAck,bufReply));
        pipeline.addLast(new StringDecoder(StandardCharsets.UTF_8));
        pipeline.addLast("stringEncoder", new StringEncoder(CharsetUtil.UTF_8));
        pipeline.addLast(new SimpleChatServerHandler());
    }
}

pipeline.addLast(new DelimiterbasedframeDecoder(5 * 1024 * 1024,bufAck,bufReply));

参数5 * 1024 * 1024 缓存数据大小，bufAck，bufReply 以“”或“”结尾

结合字符串解码器pipeline.addLast(new StringDecoder(StandardCharsets.UTF_8));一起使用。

handler即可使用string处理

public class SimpleChatServerHandler extends SimpleChannelInboundHandler {}
