Question

我有一个bean来配置SimpleRabbitListenerContainerFactory但是当我使用factory.setTaskExecutor(taskScheduler);时，我得到了这个日志，这会延迟应用启动超过300秒。但如果我评论这个 TaskExecutor ，一切正常。

延迟应用启动超过300 +

由于您只显示2毫秒的日志，而且没有一个与容器启动有关，因此很难说。

使用外部任务执行程序不应该有任何区别，只要它可以提供足够的线程来满足容器的并发性（除了使用执行程序的其他任何东西）。

编辑您的问题以显示出现此行为的确切配置（包括容器和执行程序）。

正确配置SimpleRabbitListenerContainerFactory
