Question

这是适配器配置代码..

private static final String THREAD_NAME_PREFIX = "PlainAdapterTaskScheduler";
private static final int PROCESS_SIZE = 200;
private static final int BACKLOG = 2 * 1024;
private static final long FIXED_RATE = 500;

@Value("${tcp.plain.inbound.port}")
private String inboundPort;

@Autowired
private EchoSerializer echoSerializer;

@Bean
public TcpReceivingChannelAdapter plainAdapter() {
    TcpReceivingChannelAdapter adapter = new TcpReceivingChannelAdapter();
    adapter.setConnectionFactory(plainServerFactory());
    adapter.setOutputChannel(inputWithPlain());

    return adapter;
}

@Bean
public TcpSendingMessageHandler plainHandler() {
    TcpSendingMessageHandler handler = new TcpSendingMessageHandler();
    handler.setConnectionFactory(plainServerFactory());

    return handler;
}

@Bean
public AbstractConnectionFactory plainServerFactory() {
    int port = Integer.parseInt(inboundPort);
    TcpNioServerConnectionFactory factory = new TcpNioServerConnectionFactory(port);
    factory.setBacklog(BACKLOG);
    factory.setTaskExecutor(taskSchedulerWithPlain());
    factory.setLookupHost(false);

    factory.setSerializer(echoSerializer);
    factory.setDeserializer(echoSerializer);

    // Nagle's algorithm disabled
    factory.setSoTcpNoDelay(true);

    return factory;
}

@Bean
public Executor taskSchedulerWithPlain() {
    ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
    scheduler.setPoolSize(PROCESS_SIZE);
    scheduler.setThreadFactory(plainAffinityThreadFactory());
    scheduler.setWaitForTasksToCompleteOnShutdown(true);

    return scheduler;
}

private AffinityThreadFactory plainAffinityThreadFactory() {
    return new AffinityThreadFactory(THREAD_NAME_PREFIX, SAME_CORE, DIFFERENT_SOCKET, ANY);
}

@Bean
public MessageChannel inputWithPlain() {
    return MessageChannels.queue(PROCESS_SIZE).get();
}

@Bean(name = PollerMetadata.DEFAULT_POLLER)
public PollerMetadata poller() {
    return Pollers.fixedRate(FIXED_RATE).get();
}

经营服务，和如果测试得到以下消息。

有什么警告信息？
为什么会显示此消息？

[PlainAdapterTaskScheduler-2] net.openhft.affinity.LockInventory       : No reservable CPU for Thread[PlainAdapterTaskScheduler-2,5,main]

windows和linux这些消息正常运行但是，hpux不能正常运行。

有没有人经历过同样的事情？谢谢。

该消息是OpenHFT的Java-Thread-Affinity类。并且有一个封闭的问题似乎相同：https://github.com/OpenHFT/Java-Thread-Affinity/issues/3

Peter Lawrey的回答是：

由于你只有两个cpus并且你的操作系统必须在某个地方运行（该库假定cpu 0用于操作系统），所以你只有一个cpu 1可以用来绑定。正如您所看到的，它保留了第一个线程到cpu 1以及它留下的任何其他线程，因为只剩下一个cpu。如果cpus被隔离并且你拥有的cpus比关键线程更多，那么亲和力效果最好。

Spring集成中的AffinityThreadFactory错误消息是什么？
