Java-java的nio服务器，在chrome内核访问时出现seletionkey重复

Question

while (true) {
    selector.select();
    Set<SelectionKey> selectedKeys = selector.selectedKeys();
    Iterator<SelectionKey> iterator = selectedKeys.iterator();
    while (iterator.hasNext()) {
        SelectionKey selectionKey = iterator.next();
        iterator.remove();
        if (selectionKey.isAcceptable()) {
            System.out.println("Accept!" + selectionKey);
            SocketChannel socketChannel = ((ServerSocketChannel)
                selectionKey.channel()).accept();
            if (null != socketChannel) {
                socketChannel.configureBlocking(false);
                socketChannel.register(selector, SelectionKey.OP_READ);
            }
        }
        else if (selectionKey.isReadable()) {
            System.out.println("Read!" + selectionKey);
            SocketChannel socketChannel = (SocketChannel) selectionKey.channel();
            if (socketChannel != null) {
                socketChannel.configureBlocking(false);
                ByteBuffer input = ByteBuffer.allocate(1024);
                input.clear();
                socketChannel.read(input);
                CoreController.getInstance().dispatch(
                    new RequestEvent(socketChannel, selectionKey, input));
            }
            selectionKey.interestOps(selectionKey.interestOps()
                & ~SelectionKey.OP_READ);
        }
    }
    selectedKeys.clear();
}

看你的前台代码怎么写的了，真的要用NIO给浏览器做socket 建议用websocket+NIO框架。只是学习的话，debug一下你的demo代码。多找几个demo看看～
