How to create udp protocol? I read the default is tcp

Your question

该如何创建udp 协议呢？我看了下默认是tcp的?

如果我要创建udp相关的服务端 我需要手动去扩展这部分代码吗
` this.bootstrap = new ServerBootstrap();
this.bootstrap
.group(bossGroup, workerGroup)
.channel(NettyEventLoopUtil.getServerSocketChannelClass())
.option(ChannelOption.SO_BACKLOG, ConfigManager.tcp_so_backlog())
.option(ChannelOption.SO_REUSEADDR, ConfigManager.tcp_so_reuseaddr())
.childOption(ChannelOption.TCP_NODELAY, ConfigManager.tcp_nodelay())
.childOption(ChannelOption.SO_KEEPALIVE, ConfigManager.tcp_so_keepalive())
.childOption(ChannelOption.SO_SNDBUF,
tcpSoSndBuf != null ? tcpSoSndBuf : ConfigManager.tcp_so_sndbuf())
.childOption(ChannelOption.SO_RCVBUF,
tcpSoRcvBuf != null ? tcpSoRcvBuf : ConfigManager.tcp_so_rcvbuf());

    // set write buffer water mark
    initWriteBufferWaterMark();`

    // set write buffer water mark
    initWriteBufferWaterMark();```

I don’t think it’s supported UDP yet，but you can Try like this:

BootStrap bootstrap = new BootStrap()
b.group(bossGroup)
.channel(NioDatagramChannel.class)
.option(ChannelOption.SO_BROADCAST, true)

当前都是基于TCP协议的版本，没有验证过UDP。
建议对照Netty的UDP使用来尝试是否可以拓展，如果有没法拓展的接口请联系我。欢迎提PR来共建！
