我似乎突然面对这个问题，因为这几个星期起作用了。有人知道是什么原因导致的吗？

一个exceptionCaught()事件被触发，它到达管道的尾部。这通常意味着管道中的最后一个处理程序没有处理异常。在io.netty.channel.DefaultChannelPipeline.callHandlerAdded0(DefaultChannelPipeline.java:624) at io.netty.channel.DefaultChannelPipeline.access$100(DefaultChannelPipeline.java:46) at io.netty.channel.DefaultChannelPipeline$PendingHandlerAddedTask.execute(DefaultChannelPipeline.java:1463) at io.netty.channel.DefaultChannelPipeline.callHandlerAddedForAllHandlers(DefaultChannelPipeline.java:1115) at io.netty.channel.DefaultChannelPipeline.invokeHandlerAddedIfNeeded(DefaultChannelPipeline.java:650) at io.netty.channel.AbstractChannel$AbstractUnsafe.register0(AbstractChannel.java:502) at io.netty.channel.AbstractChannel$AbstractUnsafe.access$200(AbstractChannel.java:417) atio.netty.channel.AbstractChannel$AbstractUnsafe$1.run(AbstractChannel.java:474) at io.netty.util.concurrent.AbstractEventExecutor.safeExecute$$$capture(AbstractEventExecutor.java:164) at io.netty.util.concurrent.AbstractEventExecutor.safeExecute(AbstractEventExecutor.java) at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:472) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:500) at io.netty.util.concurrent.SingleThreadEventExecutor$4.run(SingleThreadEventExecutor.java:989) at io.netty.util.internal.ThreadExecutorMap$2.在io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) at java.base/java.lang.Thread.run(Thread.java:834) io.netty.channel.ChannelPipelineException上运行(ThreadExecutorMap.java:74)：reactor.netty.resources.PooledConnectionProvider$PooledConnectionAllocator$PooledConnectionInitializer.handlerAdded()引发了一个异常；移除。在io.netty.channel.DefaultChannelPipeline.callHandlerAdded0(DefaultChannelPipeline.java:624) at io.netty.channel.DefaultChannelPipeline.access$100(DefaultChannelPipeline.java:46) at io.netty.channel.DefaultChannelPipeline$PendingHandlerAddedTask.execute(DefaultChannelPipeline.java:1463) at io.netty.channel.DefaultChannelPipeline.callHandlerAddedForAllHandlers(DefaultChannelPipeline.java:1115) at io.netty.channel.DefaultChannelPipeline.invokeHandlerAddedIfNeeded(DefaultChannelPipeline.java:650) at io.netty.channel.AbstractChannel$AbstractUnsafe.register0(AbstractChannel.java:502) at io.netty.channel.AbstractChannel$AbstractUnsafe.access$200(AbstractChannel.java:417) atio.netty.channel.AbstractChannel$AbstractUnsafe$1.run(AbstractChannel.java:474) at io.netty.util.concurrent.AbstractEventExecutor.safeExecute$$$capture(AbstractEventExecutor.java:164) at io.netty.util.concurrent.AbstractEventExecutor.safeExecute(AbstractEventExecutor.java) at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:472) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:500) at io.netty.util.concurrent.SingleThreadEventExecutor$4.run(SingleThreadEventExecutor.java:989) at io.netty.util.internal.ThreadExecutorMap$2.在io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) at java.base/java.lang.Thread.run(Thread.java:834)运行(ThreadExecutorMap.java:74)，原因是: java.util.NoSuchElementException: reactor.netty.resources.PooledConnectionProvider$PooledConnectionAllocator$PooledConnectionInitializer at io.netty.channel.DefaultChannelPipeline.getContextOrDie(DefaultChannelPipeline.java:1082) at io.netty.channel.DefaultChannelPipeline.remove(DefaultChannelPipeline.java:417) at reactor.netty.resources.PooledConnectionProvider$PooledConnectionAllocator$PooledConnectionInitializer.handlerAdded(PooledConnectionProvider.java:284) at io.netty.channel。AbstractChannelHandlerContext.callHandlerAdded(AbstractChannelHandlerContext.java:938) at io.netty.channel.DefaultChannelPipeline.callHandlerAdded0(DefaultChannelPipeline.java:609) .省略了15个通用帧

谢谢你的指针。我只在下面的依赖树中看到了与网络相关的东西。

我不知道哪一种错配会引起这个问题。

我使用的SpringBoot2.7.1与相同版本的网络流量。我使用spring本机( 0.12.0 )。我在Windows机器(使用ubuntu )上使用packeto构建包创建了一个本机映像，该映像是在本地创建并成功运行的。然而，当我部署到ECS Fargate时，我会得到上面提到的错误。

我已经以类似的方式部署了spring本地映像，但是没有问题。我不知道为什么我会得到这个春季网络流量的错误。
