在本地运行时,Netty服务器未正确关闭

在同一个jvm中运行Netty客户端和服务器并尝试停止服务器时遇到问题。这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 });
}

我用Netty 3.4.0.Final和3.4.4.Final进行了测试,我无法弄清楚我做错了什么。

为什么客户端在服务器关闭后仍然可以向服务器发送数据?

答案 0 :(得分:0)

客户端可以发送数据,但clientChannel.write(..)的ChannelFuture应该失败。

您可以查看:

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

或者使用ChannelFutureListener以异步方式进行通知。
