Netty服务器在本地运行时未正确关闭

我在同一个jvm中运行Netty客户端和服务器并试图停止服务器时遇到问题。以下是我的代码来举例说明：

@BeforeMethod
public void setUp() {
    serverBootstrap = new ServerBootstrap(new DefaultLocalServerChannelFactory());
    serverBootstrap.getPipeline().addLast("my-server-handler", new ServerHandler());
    LocalAddress local = new LocalAddress("1");
    serverChannel = serverBootstrap.bind(local);

    clientBootstrap = new ClientBootstrap(new DefaultLocalClientChannelFactory());

    clientBootstrap.setPipelineFactory(new ChannelPipelineFactory() {
        @Override
        public ChannelPipeline getPipeline() throws Exception {
            ChannelPipeline pipeline = Channels.pipeline();
            pipeline.addLast("my-client-handler", new ClientHandler());
            return pipeline;
        }
    });

    ChannelFuture future = clientBootstrap.connect(local);
    if (future.isSuccess())
        System.out.println("Client connected");
    clientChannel = future.getChannel();
}

@AfterMethod
public void tearDown() {
    closeServer();
    clientChannel.close().awaitUninterruptibly();
    clientBootstrap.releaseExternalResources();
}

@Test
public void shoulClose() {        
    sendData();
    closeServer();
    sendData();       
}

private void closeServer() {
    serverChannel.close().awaitUninterruptibly();
    serverBootstrap.releaseExternalResources();
}

private void sendData() {
    clientChannel.write(new byte[] { 1, 2, 3 });
}

我已经用Netty 3.4.0.Final和3.4.4.Final测试过了，我不知道我做错了什么

为什么在服务器被关闭后，客户端仍然可以向服务器发送数据？

客户端可以发送数据，但不能发送clientChannel.write。。应该失败

您可以通过以下方式进行检查：

boolean success = clientChannel.write(new byte[] { 1, 2, 3 }).awaitUninteruptable().isSucess();

或者使用ChannelFutureListener以异步方式获取通知
