netty发送udp广播时报错java.net.SocketException：Permission denied 

1 Bootstrap b = new Bootstrap();
2             EventLoopGroup group = new NioEventLoopGroup();
3             b.group(group)
4                     .channel(NioDatagramChannel.class)
5                     .option(ChannelOption.SO_BROADCAST, true)

只需要在后面加入.option(ChannelOption.SO_BROADCAST, true)这行代码就行
