先 看下面一道面试题: func main() { runtime.GOMAXPROCS(1) wg := sync.WaitGroup{} wg.Add(20) for i := 0; i < 10; i++ { go func() { fmt.Println("go routine 1 i: ", i) wg.Done() }() } for i := 0; i < 10; i++ { go func(i int) { fmt.Println("go rout…

Go 语言的线程是并发机制,不是并行机制. 那么,什么是并发,什么是并行? 并发是不同的代码块交替执行,也就是交替可以做不同的事情. 并行是不同的代码块同时执行,也就是同时可以做不同的事情. 举个生活化场景的例子: 你正在家看书,忽然电话来了,然后你接电话,通话完成后继续看书,这就是并发,看书和接电话交替做. 如果电话来了,你一边看书一遍接电话,这就是并行,看书和接电话一起做. 先看实例 package main import ( "fmt" "runtime" &…

Go语言在2016年再次拿下TIBOE年度编程语言称号,这充分证明了Go语言这几年在全世界范围内的受欢迎程度.如果要对世界范围内的gopher发起一次“你究竟喜欢Go的哪一点”的调查,我相信很多Gopher会提到:goroutine. Goroutine是Go语言原生支持并发的具体实现,你的Go代码都无一例外地跑在goroutine中.你可以启动许多甚至成千上万的goroutine,Go的runtime负责对goroutine进行管理.所谓的管理就是“调度”,粗糙地说调度就是决定何时哪个goro…
