一、问题描述

今天开发好的功能上到测试环境测试，服务启动后报错，开发环境启动正常，报错如下：

二、问题排查

首先根据报错可以知道是dynamic-tp动态线程池相关的报错，这次开发也确实用到了动态线程池，配置如下：

image-20241030103053642

再结合报错日志中ThreadPoolExecutor.java类的第1311行

image-20241030103523719

通过抛这个异常的if条件，可知大概率是满足了 maximumPoolSize < corePoolSize 这个条件，导致抛了异常，由于配置中未配置 maximumPoolSize，所以 maximumPoolSize 取的默认值

在dynamic-tp的配置类 TpExecutorProps 中可以找到如下代码

image-20241030103806777

再到常量类 DynamicTpConst 中找到如下代码：

image-20241030103939508

最后可以知道取值为 Runtime.getRuntime().availableProcessors()

image-20241030104032017

这是获取java虚拟机的可用处理器数，而开发机器这个值是16

image-20241030104617896

测试环境k8s只分配了1核，所以这个值是1

三、解决问题

所以原因就是 corePoolSize 配的太大了，超过了maximumPoolSize，把测试环境核心线程池大小 core-pool-size 改为1，可以正常启动了

四，后续

吐槽：为什么报错不直接告诉我原因是 corePoolSize 比 maximumPoolSize 大啊
