【Java.NIO】NIO就绪处理之OP_ACCEPT

转自： http://blog.csdn.net/zhouhl_cn/article/details/6582420

OP_ACCEPT的处理与OP_CONNECT基本一样，服务端监听，并注册OP_ACCEPT事件后，就已准备好接受客户端的连接了

 ServerSocketChannel ssc = ServerSocketChannel.open();
 ssc.configureBlocking(false);
 ssc.socket().bind(new InetSocketAddress(port));
 channel.register(selector, SelectionKey.OP_ACCEPT);

当一个客户端连接到来时，OP_ACCEPT事件就绪。

 if (key.isValid() && key.isAcceptable()) {
     ServerSocketChannel ssc = (ServerSocketChannel) key.channel();
     SocketChannel ch = ssc.accept();
     if (ch != null) {
         ch.configureBlocking(false);
         SelectionKey sk = ch.register(selector, SelectionKey.OP_READ);
     }
 }
