Question

我正在尝试将netty版本3.2.5升级到3.6.6。我的一个测试在版本3.5.9中失败并且与3.5.8一起使用。它的测试输出如下。由于某种原因，未收到服务器的响应。

消息发送由空闲处理程序的超时触发。服务器日志（下面）看起来总是一样的。我在github中找不到任何问题。我错过了什么吗？谢谢！若埃尔

ChannelPipelineFactory

public ChannelPipeline getPipeline() throws Exception {
            ChannelPipeline pipeline = Channels.pipeline();
            // logging handler
            pipeline.addLast("LOGGER", new LoggingHandler());
            // responsible for observing idle timeout - Netty
            pipeline.addLast("idleTimeout", new NettyIdleHandler(this.context, this.timer, 0, 0, this.context.getIdleTimeoutSeconds()));
            // responsible for reading until SCMP frame is complete
            pipeline.addLast("framer", new NettySCMPFrameDecoder());
            // executer to run NettyTcpRequesterResponseHandler in own thread
            pipeline.addLast("executor", new ExecutionHandler(AppContext.getSCWorkerThreadPool()));
            // responsible for handle response - Stabilit
            pipeline.addLast("requesterResponseHandler", new NettyTcpRequesterResponseHandler());
            return pipeline;
}

Answer 1

发现问题。阻止线程是一个坏主意：/。在新线程中运行空闲过程可以解决问题。猜猜它是因为IdleStateEvent现在由工作线程处理，因为它已在3.5.9中根据以下内容进行了更改： https://github.com/netty/netty/issues/641 https://issues.jboss.org/browse/NETTY-362

为什么idleStateEvent没有移交给管道中指定的我自己的工作线程作为执行器“ExecutionHandler”？或者我的错误？ THX！
