在微服务中使用领域事件   稍微回想一下计算机硬件的工作原理我们便不难发现,整个计算机的工作过程其实就是一个对事件的处理过程.当你点击鼠标.敲击键盘或者插上U盘时,计算机便以中断的形式处理各种外部事件.在软件开发领域,事件驱动架构(Event Driven Architecture,EDA)早已被开发者用于各种实践,典型的应用场景比如浏览器对用户输入的处理.消息机制以及SOA.最近几年重新进入开发者视野的响应式编程(Reactive Programming)更是将事件作为该编程模型中的一等公民.…

假如面试回答js的运行机制时,你可能说出这么一段话:"Javascript的事件分同步任务和异步任务,遇到同步任务就放在执行栈中执行,而碰到异步任务就放到任务队列之中,等到执行栈执行完毕之后再去执行任务队列之中的事件."但你能说出背后的原因吗? 先理解相关概念 线程与进程 进程:是系统资源分配和调度的单元.一个运行着的程序就对应了一个进程.一个进程包括了运行中的程序和程序所使用到的内存和系统资源. 线程:线程是进程下的执行者,一个进程至少会开启一个线程(主线程),也可以开启多个线程.…
