ThreadPoolExecutor初始化一个ThreadPoolExecutor从初始化到执行需要经历如下几个环节。ThreadPoolExecutor.executeThreadPoolExecutor.addWorkernew Worker(firstTask)getThreadFactory().newThread(this)new Thread(ThreadGro

上一篇主要从代码角度介绍了线程池关闭相关的方法，包括各个方法之间的逻辑关系，调用关系和产生的效果。这一篇更多从逻辑角度上来说一下线程池在shutdown之后，原来正常的处理流程有哪些变化，既是总结也是扩展。shutdown操作之后，首先最重要的一点变化就是线程池状态变成了SHUTDOWN。该状态是开始关闭线程池之后，从RUNNING改变状态经过的第一个状态(还有一种情况是直接进STOP，调

补充了和Thread的interrupt操作相关的知识，回头再来看ThreadPoolExecutor中interrupt，关闭线程池等相关操作。1.interruptIdleWorkers/** * Interrupts threads that might be waiting for tasks (as * indicated by not being locke
