NIO的陷阱(一)SocketChannel.open(new InetSocketAddress(hostIp, hostListenningPort))与SocketChannel.o
NIO的陷阱(一)
SocketChannel.open(new InetSocketAddress(hostIp, hostListenningPort))与SocketChannel.open(),socketChannel.connect(new InetSocketAddress(hostIp, hostListenningPort))的比较
相同点:这两种写法实现的功能一样,都是打开通道并连上服务端
不同点:前一种不能监听到socketChannel.register(selector,SelectionKey.OP_CONNECT)事件
