JavaConcurrencyInPractice-线程池的使用 1、摘要 线程池的使用使得任务的提交与执行解耦开来,但是,线程池可以执行所有任务吗? 答案是——不能,线程池中封装了任务的执行策略,提供了几种执行策略的实现, 但是,不是所有的任务都能由这些策略来执行的: 1、依赖性任务,任务的执行依赖其他任务。 2、使用线程封闭机制的...

JavaConcurrencyInPractice-任务执行 1、任务 什么是任务? 任务通常是一组抽象且离散的工作单元,通过把程序的功能分解到多个任务, 可以简化程序结构,优化错误处理,以及提供自然的并行工作结构。 找出任务的边界: 在理想的情况下,任务应该是相互独立的,任务的独立有助于实现并发。

首先明确一点,java中不能抢占式的停止一个任务,只能通过cooperative协调机制来停止任务。在第5章中提到过,一些阻塞库的方法支持interruption‘中断’,线程中断是一种协调机制:线程A可以通知线程B在它觉得合适的时候,如果它愿意停止自己的工作。 最简单的一种方式:通过设置一个flag变量(必须是volatile),定期的检查,如果...
