Aio Socket通信报错，且无法正确获取数据

[孙海峰VIP]

代码如下：

public class AioServer {
	private AsynchronousServerSocketChannel server;
	private ByteBuffer send = ByteBuffer.allocate(2048);
	private ByteBuffer recive = ByteBuffer.allocate(2048);

	public AioServer(int port) throws IOException {
		server = AsynchronousServerSocketChannel.open().bind(new InetSocketAddress(port));
	}

	public void startup() throws Exception {
		System.out.println("========服务已启动=========");
		AsynchronousChannelGroup group = AsynchronousChannelGroup.withThreadPool(Executors.newFixedThreadPool(4));

		// 监听客户端连接
		server.accept(null, new CompletionHandler<AsynchronousSocketChannel, Void>() {

			@Override
			public void completed(AsynchronousSocketChannel result, Void attachment) {
				recive.clear();
				result.read(recive); //接收客户端数据
				System.out.println("?????"+new String(recive.array()));
				send.clear();
				send.put(doSomething().getBytes());
				send.flip();
				result.write(send); //反馈结果
			}
			
			private String doSomething() {
				//此处应有业务逻辑
				return "处理成功";
			}

			@Override
			public void failed(Throwable exc, Void attachment) {
				
			}

		});
		
		group.awaitTermination(Long.MAX_VALUE, TimeUnit.SECONDS);
	}

	public static void main(String[] args) {
		try {
			new AioServer(9000).startup();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

public class AioClient {

	private int port;
	private ByteBuffer send = ByteBuffer.allocate(2048);
	private ByteBuffer recive = ByteBuffer.allocate(2048);

	public AioClient(int port) {
		this.port = port;
	}

	public Object send(String message) throws IOException {
		AsynchronousSocketChannel client = AsynchronousSocketChannel.open();
		for (;;) {
			client.connect(new InetSocketAddress(port), null, new CompletionHandler<Void, AsynchronousSocketChannel>() {

				@Override
				public void completed(Void result, AsynchronousSocketChannel attachment) {
					send.clear();
					send.put(message.getBytes());
					send.flip();
					attachment.write(send);
					recive.clear();
					attachment.read(recive);
					System.out.println("计算结果:" + new String(recive.array()));
					
				}

				@Override
				public void failed(Throwable exc, AsynchronousSocketChannel attachment) {
					
				}

			

			});
		}
	}

	public static void main(String[] args) {
		try {
			new AioClient(9000).send("hello aio");
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

运行上述代码客户端将会抛出如下异常

Exception in thread "main" java.nio.channels.ConnectionPendingException
	at sun.nio.ch.UnixAsynchronousSocketChannelImpl.implConnect(UnixAsynchronousSocketChannelImpl.java:314)
	at sun.nio.ch.AsynchronousSocketChannelImpl.connect(AsynchronousSocketChannelImpl.java:209)
	at com.threadtest.aio.AioClient.send(AioClient.java:30)
	at com.threadtest.aio.AioClient.main(AioClient.java:57)
Exception in thread "Thread-9" 

初次接触Aio对此不是很熟，求指点迷津。
