bootstrap.group(group).channel(NioSocketChannel.class)//设置channel类型
.option(ChannelOption.TCP_NODELAY, true)//在TCP/IP协议中，无论发送多少数据，总是要在数据前面加上协议头，同时，对方接收到数据，也需要发送ACK表示确认。为了尽可能的利用网络带宽，TCP总是希望尽可能的发送足够大的数据。这里就涉及到一个名为Nagle的算法，该算法的目的就是为了尽可能发送大块数据，避免网络中充斥着许多小数据块。 TCP_NODELAY就是用于启用或关于Nagle算法。如果要求高实时性，有数据发送时就马上发送，就将该选项设置为true关闭Nagle算法；如果要减少发送次数减少网络交互，就设置为false等累积一定大小后再发送。默认为false。
.option(ChannelOption.SO_KEEPALIVE, true)//是否启用心跳保活机制。在双方TCP套接字建立连接后（即都进入ESTABLISHED状态）并且在两个小时左右上层没有任何数据传输的情况下，这套机制才会被激活。
.option(ChannelOption.SO_REUSEADDR, true)//这个套接字选项通知内核，如果端口忙，但TCP状态位于 TIME_WAIT ，可以重用端口。如果端口忙，而TCP状态位于其他状态，重用端口时依旧得到一个错误信息，指明"地址已经使用中"。如果你的服务程序停止后想立即重启，而新套接字依旧使用同一端口，此时 SO_REUSEADDR 选项非常有用。必须意识到，此时任何非期望数据到达，都可能导致服务程序反应混乱，不过这只是一种可能，事实上很不可能
.option(EpollChannelOption.SO_REUSEPORT, true)//SO_REUSEPORT支持多个进程或者线程绑定到同一端口，提高服务器程序的性能
